[Modes for carrying out the invention]

[0025] The ultrasound diagnostic apparatus of the present invention comprises an ultrasound probe that is brought into contact with a subject to transmit and receive ultrasound waves, an operation unit having multiple input elements for inputting at least ultrasound-related information, a patient's bed for which the subject is placed, and a display unit that displays an ultrasound image generated by processing the ultrasound signal received by the ultrasound probe, as well as measurement results and the like.

[0026] The ultrasound diagnostic apparatus of the present invention includes a support section that supports each component of the ultrasound diagnostic apparatus. The support section supports the operating section and the patient section so that they can move up and down, and also supports the display section and the patient section so that they can move up and down. Furthermore, the ultrasound diagnostic apparatus of the present invention includes a storage section for housing a plurality of ultrasound probes. The support section supports the storage section.

[0027] The ultrasound diagnostic device of the present invention can also be described as an ultrasound diagnostic device with a patient table, an ultrasound diagnostic system, an ultrasound imaging system, and so on.

[0028] Preferred embodiments of the present invention will be described below with reference to the attached drawings.

[0029] Figures 1 to 3 show the configuration of the ultrasound diagnostic apparatus of the present invention. Figures 1 and 3 are perspective views of the ultrasound diagnostic apparatus. Figure 2 is a top view of the ultrasound diagnostic apparatus.

[0030] The ultrasound diagnostic device is equipped with a base portion 102 that supports it against the floor. The base portion 102 is a component that comes into contact with the floor. The base portion 102 is fixed to the floor using screws or the like. If the base portion 102 is released from its fixation to the floor, the operator can move the ultrasound diagnostic device. Here, a configuration in which the base portion 102 is installed on the floor is shown, but it is also possible to fix another base portion (not shown) to the ceiling and suspend the ultrasound diagnostic device from the ceiling.

[0031] The ultrasound diagnostic device is erected on the floor or ceiling and includes a support section 104 that supports each component of the ultrasound diagnostic device. The support section 104 is integrated with the base section 102. The support section 104 is a member that extends in the vertical direction and can also be described as a support column. The support section 104 installs and supports each component of the ultrasound diagnostic device in the vertical direction.

[0032] The ultrasound diagnostic device includes a patient bed 106 on which the patient is placed. The patient is placed on the upper surface of the patient bed 106. The support 104 supports the patient bed 106 so that its upper surface is horizontal. The patient bed 106 is supported by the support 104 via a sliding part 108 installed on the support 104. The sliding part 108 has a groove 110 formed in the horizontal direction. A patient bed support member 114 installed on the lower surface of the patient bed 106 is fitted into the groove 110 of the sliding part 108. By moving the patient bed support member 114 of the patient bed 106 horizontally relative to the groove 110 of the sliding part 108, the patient bed 106 can slide horizontally (direction A) via the sliding part 108. The horizontal direction (direction A) is the longitudinal direction of the patient bed 106.

[0033] Furthermore, the bed section 106 is supported by the support section 104 via a connecting section 112 installed on the support section 104. Since the connecting section 112 is supported so as to be movable in the vertical direction relative to the support section 104, the bed section 106 can be moved in the vertical direction (direction B). In other words, the support section 104 supports the bed section 106 so as to be movable in the vertical direction. In order to support the bed section 106 and the patient under load, the support section 104 located below the bed section 106 has a longer circumference and is thicker than the support section 104 located above the bed section 106. By changing the circumference of the support section 104 in this way, the rigidity of the ultrasound diagnostic device is maintained.

[0034] The ultrasound diagnostic device includes a panel unit 120 comprising multiple components. The panel unit 120 has a display unit 122 that displays ultrasound images generated by processing ultrasound signals and measurement results. The display unit 122 is rotatably mounted on the panel unit 120. The operator can set the display unit 122 to a landscape or portrait orientation by rotating it. The display unit 122 shown in Figure 1 is in the landscape orientation. The operator can set the display unit 122 to a portrait orientation by rotating it 90 degrees. The display unit 122 can also change the arrangement of ultrasound images and measurement results according to the rotation angle of the display unit 122.

[0035] The panel unit 120 has an operating section 124 for operation by the operator. The panel unit 120 also includes an ultrasonic transducer holder 126 for mounting an ultrasonic transducer, a bottle storage section 128 for storing an ultrasonic gel bottle, and a tissue paper box 130 for removing ultrasonic gel that has adhered to the subject. The operating section 124 is installed at one end (left side) of the panel unit 120. The ultrasonic transducer holder 126, the bottle storage section 128, and the tissue paper box 130 are installed at the other end (right side) of the panel unit 120. The panel unit 120 is configured such that a display section 122 is installed between the operating section 124, the ultrasonic transducer holder 126, the bottle storage section 128, and the tissue paper box 130.

[0036] The ultrasonic transducer holder 126 is a holding part for temporarily placing the ultrasonic transducer 144 used for ultrasonic imaging. The lower surface of the ultrasonic transducer holder 126 protrudes from the panel unit 120. The lower surface of the ultrasonic transducer holder 126 is a curved surface. The ultrasonic transducer holder 126 can hold the ultrasonic transmitting and receiving surface (head part) of the ultrasonic transducer 144 at the lower surface of the ultrasonic transducer holder 126.

[0037] The bottle storage section 128 has a function to warm the ultrasonic gel bottle (gel warmer function). The bottle storage section 128 can keep the ultrasonic gel bottle warm at a predetermined temperature (for example, 35-40°C).

[0038] In this way, the panel unit 120 can hold the items necessary when using the ultrasound diagnostic device. Therefore, the operator can operate the control panel of the ultrasound diagnostic device and obtain the necessary items without changing their posture.

[0039] The panel unit 120 is connected to the bed section 106 via a connecting section 112. The connecting section 112 is installed along the longitudinal direction of the support section 104. The longitudinal direction of the connecting section 112 is parallel to the longitudinal direction of the support section 104. The support section 104 has, for example, a groove or rail (not shown) formed along its longitudinal direction. A part of the connecting section 112 is fitted into the groove or rail of the support section 104, and the connecting section 112 is installed on the support section 104. Therefore, even if a load such as the bed section 106 is applied to the connecting section 112, it can maintain the configuration shown in Figure 1.

[0040] Furthermore, the connecting portion 112 is installed on the support portion 104 so as to be movable in the vertical direction. Since the connecting portion 112 can move vertically relative to the support portion 104, the panel unit 120 can be moved vertically (direction C). The display portion 122 and the operation portion 124 installed on the panel unit 120 can move vertically via the connecting portion 112.

[0041] The operating unit 124 is installed on the panel unit 120 via an arm 132. The arm 132 has a structure in which multiple long cylindrical sections are interlocked. In other words, the arm 132 has a nesting structure and can extend and retract in the longitudinal direction (direction D). The position of the operating unit 124 can be changed by extending or retracting the arm 132. The arm 132 is also installed on the panel unit 120 via a hinge section, which will be described later. The hinge section serves as the pivot axis of the arm 132, allowing the arm 132 to rotate in a predetermined rotational direction (direction E). Therefore, the operator can fold the arm 132 via the hinge section. By folding the arm 132, the operator can store the operating unit 124 in the panel unit 120.

[0042] In this example, the display unit 122 and the operation unit 124 are shown to be supported by the support unit 104 via the panel unit 120. However, the display unit 122 and the operation unit 124 may be directly supported by the support unit 104. In that case, the display unit 122 and the operation unit 124 can move independently in the vertical direction.

[0043] The ultrasound diagnostic device includes a frame section 140. The support section 104 supports the frame section 140. The frame section 140 is supported at the top of the support section 104. The frame section 140 is a rectangular annular member. To reduce the feeling of pressure on the patient placed on the examination table section 106, the central part of the frame section 140 is hollow. Multiple ultrasound probes 142 and 144 are installed in the frame section 140. The frame section 140 can also be described as a housing for the ultrasound probes.

[0044] Furthermore, the ultrasonic transducer housing is installed in the frame 140 so that the ultrasonic transducer 144 and the operating unit 124 do not interfere with (contact with) each other when the ultrasonic transducer 144 used for imaging is pulled out (lowered) from the ultrasonic transducer cable housing. Here, we will describe the ultrasonic transducer 144 as the ultrasonic transducer used for imaging, but the same applies to other ultrasonic transducers 142. Specifically, the ultrasonic transducer housing is installed in the frame 140 on the right side when viewed from the front of the ultrasound diagnostic device. The ultrasonic transducer 144 used for imaging descends from the frame 140 to the right side of the panel unit 120 (near the ultrasonic transducer holder 126 and the bottle housing 128). In this way, the ultrasonic transducer housing is installed directly above the ultrasonic transducer holder 126 and the bottle housing 128. Therefore, since the ultrasonic probe 144 descends from the frame 140 near the ultrasonic probe holder 126, the ultrasonic probe 144 can be temporarily placed on the ultrasonic probe holder 126.

[0045] On the other hand, the control unit 124 is located on the left side when viewed from the front of the ultrasound diagnostic device. Specifically, the control unit 124 is located to the left of the panel unit 120. In this way, the housing for the ultrasound probe is not installed on the frame unit 140 directly above the control unit 124. Therefore, even if the ultrasound probe 144 used for imaging descends from the frame unit 140, the ultrasound probe 144 will not interfere with (contact) the control unit 124.

[0046] As described above, the support section 104 is erected on the floor or ceiling and supports each component. Here, the support section 104 supports the bed section 106, the operating section 124, and the frame section 140 (storage section for the ultrasonic probe) spaced apart in the vertical direction. The support section 104 also supports the bed section 106, the display section 122, and the frame section 140 (storage section for the ultrasonic probe) spaced apart in the vertical direction. The support section 104 is divided into three areas: upper, middle, and lower, and supports each component spaced apart in the vertical direction.

[0047] The support section 104 supports each component such that each component protrudes in one direction (the direction towards the viewer in Figure 1: a direction perpendicular to directions A and B). The support section 104 is a so-called cantilever structure, and supports each component without any external support other than the support section 104. The bed section 106, the operating section 124, the display section 122, and the frame section 140 (storage section for the ultrasonic probe) are installed so that they protrude in one direction relative to the support section 104. When the bed section 106, the operating section 124 or the display section 122, and the frame section 140 (storage section for the ultrasonic probe) are installed spaced apart from the support section 104, each component forms a layered structure.

[0048] Specifically, the bed section 106 is supported at the bottom of the support section 104. The display section 122 and the operation section 124 are supported in the middle of the support section 104. The frame section 140 (storage section for the ultrasonic probe) is supported at the top of the support section 104. The display section 122 is installed above the bed section 106, and the operation section 124 is installed above the bed section 106. In other words, the display section 122 is installed at a higher position than the bed section 106. Also, the operation section 124 is installed at a higher position than the bed section 106.

[0049] The frame section 140 is installed above the display section 122, and the frame section 140 is installed above the operation section 124. In other words, the frame section 140 is installed at a higher position than the display section 122. Also, the frame section 140 is installed at a higher position than the operation section 124.

[0050] Furthermore, a frame section 140 (storage section for ultrasonic probes) is installed directly above the bed section 106. Therefore, when multiple ultrasonic probes 142 and 144 are lowered from the frame section 140, the ultrasonic probes will be positioned on the bed section 106.

[0051] Since the display unit 122 is installed above the patient bed 106, the operator can check the condition of the patient placed on the patient bed 106, the contact points of the ultrasonic probe 144 used for imaging the patient, and observe the ultrasonic image and measurement results displayed on the display unit 122. Furthermore, since the control unit 124 is installed above the patient bed 106, the operator can check the condition of the patient, the installation location of the ultrasonic probe 144 used for imaging, and operate the control unit 124. In the ultrasonic diagnostic apparatus of the present invention, it is assumed that the operator stands and operates the apparatus near the center of the longitudinal direction of the patient bed 106. Therefore, the display unit 122, control unit 124, ultrasonic probe 144, and patient bed 106 can be installed in front of the operator. As a result, the operator can perform imaging in a natural posture without twisting their body.

[0052] The support section 104 supports each component by having each component protrude in one direction (the direction towards the viewer in Figure 1: a direction perpendicular to directions A and B). Therefore, the back surface of the support section 104 (the opposite direction to the viewer in Figure 1) does not have any protruding components. As a result, the operator can bring the back surface of the support section 104 close to the wall of the examination room, and the ultrasound diagnostic device can be installed near the wall of the examination room. Because the ultrasound diagnostic device can be installed on the wall side of the examination room, space in the examination room can be secured.

[0053] Figure 2 is a top view of the ultrasound diagnostic apparatus. Details of the patient table 106 and the control unit 124 of the ultrasound diagnostic apparatus will be explained using Figure 2.

[0054] The bed section 106 is composed of three main frames. Specifically, the bed section 106 consists of a first frame 450 that supports the patient's waist, a second frame 452 that supports the patient's upper body, and a third frame 454 that supports the patient's lower body.

[0055] The first frame 450 has gripping parts 400 and 402 for the subject or operator to grasp. When the subject gets onto the bed 106, the subject grasps at least one of the gripping parts 400 and 402. The subject can support their body with the gripping parts 400 and 402. The subject moves while grasping the gripping parts 400 and 402 so that their waist is positioned on the first frame 450. The subject is placed near the center of the bed 106. The subject may also grasp the gripping parts 400 and 402 with both hands. When the subject gets onto or off the bed 106, the operating unit 124 is stored in the panel unit 120.

[0056] Furthermore, if the operator wants to slide the bed section 106 horizontally (direction A), the operator grasps the gripping section 400 and pulls the bed section 106 in the desired direction. The operator can then slide the bed section 106 horizontally. The presence of the gripping section 400 and gripping section 402 on the bed section 106 improves its operability.

[0057] The first frame 450 is fixed to the bed support member 114 shown in Figure 1. The bed support member 114 supports the first frame 450 so that it remains horizontal. The first frame 450 and the second frame 452 are separated by a dividing groove 420. A tilt axis is installed in the dividing groove 420. The ends of the first frame 450 and the second frame 452 are connected to the tilt axis. The first frame 450 and the second frame 452 are structured to bend around the tilt axis installed in the dividing groove 420. The second frame 452 tilts around the tilt axis so that the angle between the first frame 450 and the second frame 452 becomes a smaller angle (an angle less than 180 degrees). At this time, the first frame 450 remains horizontal without rotating around the tilt axis. By tilting the second frame 452, the bed section 106 can be reclined.

[0058] Similarly, the first frame 450 and the third frame 454 are separated by a dividing groove 422. A tilt axis is installed in the dividing groove 422. The ends of the first frame 450 and the third frame 454 are connected to the tilt axis. The first frame 450 and the third frame 454 are structured to bend around the tilt axis installed in the dividing groove 422. The third frame 454 can be tilted around the tilt axis so that the angle between the first frame 450 and the third frame 454 becomes a superior angle (an angle greater than 180 degrees). At this time, the first frame 450 remains horizontal without rotating around the tilt axis. By tilting the third frame 454, the bed section 106 can be reclined.

[0059] The bed section 106 has multiple grooves (grooves 404, 406, and 408) formed in the first frame 450, the second frame 452, and the third frame 454, respectively. The bed section 106 can be separated by these multiple grooves. Groove 404 allows for the separation of a member of the first frame 450 where the gripping part 400 is located. By separating the member of the first frame 450 where the gripping part 400 is located, the bed section 106 can be made into a U-shape. Similarly, for the second frame 452 and the third frame 454, parts of the members of the second frame 452 and the third frame 454 can be separated by grooves 406 and 408, respectively.

[0060] The operating unit 124 is installed on the panel unit 120 via an arm 132. The arm 132 is installed on the panel unit 120 via a hinge 134 (first hinge). The hinge 134 is, for example, a torque hinge. The torque hinge is a hinge that can stop the arm 132 at any position while it is opening or closing. The torque hinge has rotational torque that can withstand the weight of the arm 132 and the operating unit 124. The rotational torque of the torque hinge can be adjusted by an adjustment screw (not shown). In this way, the hinge 134 allows the arm 132 to be rotated to a predetermined angle. Therefore, as shown in Figure 2, the operating unit 124 can be extended and installed above (directly above) the bed section 106.

[0061] Even when a patient is placed on the bed section 124, the arm 132 can be rotated to a predetermined angle so that the operating section 124 does not come into contact with the patient, thereby extending the operating section 124. For example, the predetermined angle can be set to 120 degrees. The arm 120 can be rotated so that the angle between the panel unit 120 and the arm 132 ranges from 0 degrees to 120 degrees.

[0062] Figure 3 is a perspective view of the ultrasound diagnostic device. The housing configuration of the operating unit 124 of the ultrasound diagnostic device will be explained using Figure 3.

[0063] As shown in Figures 1 and 2, the arm 132 supporting the operating unit 124 can be folded by rotating the arm 132. Specifically, as described above, a hinge 134 is installed between the panel unit 120 and the arm 132. A hinge (second hinge: not shown) is also installed between the operating unit 124 and the arm 132. The operating unit 124 is installed on the arm 132 via the hinge. Specifically, a hinge is installed on the back of the operating unit 124. The function of this hinge (second hinge) is the same as that of hinge 134 (first hinge), so its explanation is omitted.

[0064] As shown above, the arm 132 is attached to the panel unit 120 via a hinge portion 134 (first hinge portion). The operating unit 124 is attached to the arm 132 via a hinge portion (second hinge portion). The arm 132 can be folded via the two hinge portions located at both ends of the arm, as shown in Figure 3. At this time, the arm 132 is sandwiched between the panel unit 120 and the operating unit 124. In this way, the operating unit 124 can be stored in the panel unit 120. When the operating unit 124 is stored in the panel unit 120, the operating surface of the operating unit 124 faces forward. Because the operating surface of the operating unit 124 faces forward, as shown in Figure 3, even when the operating unit 124 is stored, the operator can operate the operating unit 124 and perform ultrasound diagnostic imaging.

[0065] Here, the internal configuration of the ultrasound diagnostic device will be explained using Figure 4. Figure 4 shows the main body 10 of the ultrasound diagnostic device. The main body 10 is installed, for example, inside the support section 104 or inside the panel unit 120. The main body 10 may be installed anywhere in the ultrasound diagnostic device.

[0066] The main unit 10 of the device comprises a transmitting and receiving unit 12 that transmits and receives ultrasonic waves to and from ultrasonic probes 142 and 144, a signal processing unit 14 that performs various signal processing using ultrasonic signals based on reflected wave signals received by the transmitting and receiving unit 12, an ultrasonic image generation unit 16 that generates an ultrasonic image using the signal processing data processed by the signal processing unit 14, and a control unit 18 that controls various components. The control unit 18 controls a drive unit 150 for moving the plurality of ultrasonic probes 142 and 144 in the vertical direction, and a drive unit 200 for moving the panel unit 120 (display unit 122 and operation unit 124) and the patient bed unit 106 in the vertical direction, which will be described later.

[0067] Here, the ultrasonic transducer 144 is used for imaging. The transmitting / receiving unit 12 controls the transmission and reception of ultrasonic waves performed by the ultrasonic transducer 144. The transmitting / receiving unit 12 includes a transmitting unit, a transmission delay circuit, etc., and supplies a drive signal to the ultrasonic transducer 144. The transmitting unit repeatedly generates rate pulses at a predetermined repetition frequency (PRF). The transmission delay circuit also provides a delay time to the rate pulses generated by the transmitting unit to focus the ultrasonic waves generated from the ultrasonic transducer 144 and determine the transmission directivity. By changing the delay time provided to the rate pulses, the transmission delay circuit can control the transmission direction of the ultrasonic waves transmitted from the transducer.

[0068] The transmitting / receiving unit 12 also includes an amplifier, an A / D converter, a receiving delay circuit, an adder, etc. It generates an ultrasonic signal by performing various processes on the reflected wave signal received by the ultrasonic probe 144. The amplifier amplifies the reflected wave signal for each channel and performs gain correction processing. The A / D converter performs A / D conversion on the gain-corrected reflected wave signal. The receiving delay circuit imparts a delay time to the digital data to determine the receiving directivity. The adder performs summing processing on the reflected wave signal to which the delay time has been applied by the receiving delay circuit. Through the summing processing of the adder, the reflected component from the direction corresponding to the receiving directivity of the reflected wave signal is emphasized.

[0069] When scanning a subject in two dimensions, the transmitting / receiving unit 12 causes the ultrasonic transducer 144 to transmit two-dimensional ultrasound waves. The transmitting / receiving unit 12 then generates a two-dimensional ultrasound signal from the two-dimensional reflected wave signal received by the ultrasonic transducer 144. When scanning a subject in three dimensions, the transmitting / receiving unit 12 causes the ultrasonic transducer 144 to transmit three-dimensional ultrasound waves. The transmitting / receiving unit 12 then generates a three-dimensional ultrasound signal from the three-dimensional reflected wave signal received by the ultrasonic transducer 144.

[0070] The signal processing unit 14 performs various signal processing operations on the ultrasonic signal output from the transmitting / receiving unit 12. Specifically, the signal processing unit 14 performs signal processing operations such as detection and logarithmic compression on the ultrasonic signal. The signal processing unit 14 visualizes the amplitude information of the ultrasonic signal and generates signal processing data (raster data). It performs bandpass filtering on the ultrasonic signal output from the transmitting / receiving unit 12, and then detects the envelope of the output signal. Then, it compresses the detected data by logarithmic transformation. The signal processing unit 14 outputs the processed signal data to the ultrasonic image generation unit 16.

[0071] The ultrasound image generation unit 16 generates an ultrasound image using the signal processing data processed by the signal processing unit 14. The ultrasound image generation unit 16 has a digital scan converter and converts the signal processing data into data represented in orthogonal coordinates. Here, the ultrasound image generation unit 16 orthogonally transforms the signal processing data (raster data) to the coordinate system (X,Y) of the image data for display. Then, the ultrasound image generation unit 16 generates an ultrasound image (B-mode image data) in which the signal intensity is represented by the brightness of the luminance. In this way, the ultrasound image generation unit 16 generates an ultrasound image. As for the ultrasound image generation algorithm, not only phase addition processing but also any algorithm can be applied to perform image reconstruction.

[0072] Furthermore, the ultrasound image generation unit 16 can generate blood flow image data using a color Doppler method called color flow mapping (CFM). In the color Doppler method, ultrasound waves are transmitted multiple times in the same direction, and frequency analysis based on the Doppler effect is performed on the received reflected wave signals to extract information about the motion of blood flow. The ultrasound image generation unit 16 generates blood flow information such as average velocity, variance, and power as blood flow image data using the color Doppler method. The ultrasound image generation unit 16 may also generate blood flow image data using the power Doppler method.

[0073] The control unit 124 has multiple input elements and receives at least information related to ultrasound. This ultrasound-related information includes, for example, information regarding ultrasound transmission, ultrasound stopping, ultrasound depth, ultrasound repetition frequency, and ultrasound measurement. The multiple input elements include a keyboard, trackball, and various buttons. The control unit 124 receives various instructions from the operator and transmits these instructions to the control unit 18 of the main unit 10. For example, the measuring caliper moves on the ultrasound image according to the movement of the trackball or other element on the control unit 104. The operator aligns the measuring caliper to the measurement range of the measurement site. Then, by pressing the confirmation button, the operator can obtain the size of the measurement range (e.g., distance, perimeter, or area).

[0074] The display unit 122 displays a GUI for the operator to input various instructions using the control unit 124, and also displays ultrasound images, blood flow image data, measurement results, etc., generated by the main unit 10 of the device.

[0075] Multiple ultrasonic probes 142 and 144 are connected to the main body 10 of the device. Each of the multiple ultrasonic probes 142 and 144 has multiple transducers, and by driving the multiple transducers, ultrasonic waves can be generated. The multiple ultrasonic probes 142 and 144 receive reflected waves from the subject and convert them into electrical signals. The converted electrical signals are transmitted to the main body 10 of the device.

[0076] Furthermore, each of the multiple ultrasonic probes 142 and 144 is provided on the front side (subject side) of the multiple transducers and includes an acoustic matching layer that matches the acoustic impedance of the multiple transducers and the subject, and a backing material provided on the back side of the multiple transducers that prevents the propagation of ultrasonic waves from the multiple transducers to the back side.

[0077] Multiple ultrasonic probes 142 and 144 are detachably connected to the frame 140 (storage section for ultrasonic probes). Types of ultrasonic probes include linear, sector, convex, radial, and 3D scanning types, and the operator can select the appropriate type of ultrasonic probe according to the imaging purpose. Furthermore, the type of sensor applied to the ultrasonic probe is not limited to conventional bulk PZT-based probes. Capacitive probes of the CMUT type, which utilize microfabrication technology, and probes of the PMUT type, which combine piezoelectric thin-film technology, can also be used.

[0078] Figures 5-7B show the vertical drive of the components in the ultrasonic diagnostic apparatus of the present invention.

[0079] Figure 5 shows a configuration in which the operator 200 photographs a subject while standing. It is assumed that the operator 200 stands and operates the device near the center of the longitudinal direction of the bed section 106. The operator uses the ultrasonic probe 144, which descends from the frame section 140 (storage section for the ultrasonic probe), and the control unit 124 to photograph the subject (not shown) placed on the bed section 106. The ultrasonic probe 144 can transmit and receive ultrasonic waves based on electrical signals sent from the cable 146. At this time, the operator 200's right hand 202 grasps the ultrasonic probe 144, and the operator 200's left hand 204 operates the control unit 124.

[0080] In this way, the display unit 122, the control unit 124, the ultrasound probe 144, and the patient table 106 can be installed directly in front of the operator 200. Therefore, the operator 200 can perform imaging in a natural posture, facing the ultrasound diagnostic device and the patient directly.

[0081] The operator 200 can position the display unit 122 at any desired location. Since the connecting unit 112 can move vertically relative to the support unit 104, the operator 200 can move the panel unit 120 vertically. The display unit 122 installed on the panel unit 120 can move vertically (direction C). Therefore, the display unit 122 can be positioned at the same height as the operator's eyes.

[0082] The control unit 18 of the ultrasound diagnostic device can also automatically control the height of the display unit 122 and the control unit 124 according to the body shape information of the operator 200. The ultrasound diagnostic device is equipped with a sensor (not shown) that reads the body shape information (height, etc.) of the operator 200. The body shape information of the operator 200 output from the sensor is transmitted to the control unit 18. Based on the operator's body shape information, the control unit 18 controls the drive unit 200 (up and down drive unit), which will be described later, to adjust the height of the display unit 122 and the control unit 124. Specifically, the control unit 18 adjusts the height of the display unit 122 and the control unit 124 so that the upper end of the display unit 122 is at a height that matches the height of the operator 200, or so that the position of the control unit 124 is at a height that matches the waist of the operator 200. This can alleviate the bending posture of the operator 200 at the waist.

[0083] Furthermore, the control unit 18 of the ultrasound diagnostic device can automatically control the height of the display unit 122 and the operation unit 124 according to the body shape information of the operator 200 that has been stored in advance. The storage unit 20 can store the body shape information of the operator 200, and the operator 200 can store this body shape information in the storage unit 20 in advance. For example, the operator 200 can store their height, line of sight position, etc., in the storage unit 20.

[0084] When operator 200 operates the ultrasound diagnostic device, the operator 200's body shape information is transmitted from the storage unit 20 to the control unit 18. Based on the operator 200's body shape information, the control unit 18 controls the drive unit 200 (up / down drive unit) to adjust the height of the display unit 122 and the operation unit 124. Specifically, the control unit 18 adjusts the height of the display unit 122 and the operation unit 124 so that the upper edge of the display unit 122 is at a height that matches the operator 200's height. The control unit 18 can also adjust the height of the display unit 122 and the operation unit 124 so that the screen of the display unit 122 is at a height that matches the operator 200's line of sight (for example, so that the line of sight is horizontal).

[0085] Furthermore, the control unit 18 of the ultrasound diagnostic device can also automatically control the height of the display unit 122 and the operation unit 124 based on setting information set for each operator. The storage unit 20 can store setting information (for example, the height of the display unit 122 and the operation unit 124) set by multiple operators, and stores each operator's setting information in the storage unit 20. When operator 200 operates the ultrasound diagnostic device, the fact that operator 200 is operating the operation unit 124 is obtained from the ultrasound diagnostic device's login information and transmitted to the control unit 18. Based on operator 200's login information, operator 200's setting information is transmitted from the storage unit 20 to the control unit 18. Based on operator 200's setting information, the control unit 18 controls the drive unit 200 (up / down drive unit) to adjust the height of the display unit 122 and the operation unit 124. When another operator operates the device, the control unit 18 controls the drive unit 200 (up / down drive unit) to adjust the height of the display unit 122 and the operation unit 124 based on the other operator's setting information.

[0086] Furthermore, the operator 200 can set the bed section 106 to any position. Since the connecting section 112 can move vertically relative to the support section 104, the bed section 106 can be moved vertically (direction B).

[0087] The panel unit 120 is connected to the bed section 106 via a connecting section 112, and the distance between the panel unit 120 and the bed section 106 is kept constant. However, the distance between the panel unit 120 and the bed section 106 can be arbitrarily adjusted according to the operator's height and intended use. For example, the operator can adjust the distance between the panel unit 120 and the bed section 106 between 50 cm and 100 cm.

[0088] When the operator moves the display unit 122 installed on the panel unit 120 in the vertical direction, the bed unit 106 moves vertically in accordance with the movement of the display unit 122. Similarly, when the operator moves the control unit 124 installed on the panel unit 120 in the vertical direction, the bed unit 106 also moves vertically in accordance with the movement of the control unit 124.

[0089] In other words, the display unit 122 and the bed unit 106 are supported by the support unit 104 so as to be linked to each other in the vertical direction. The display unit 122 and the bed unit 106 move in conjunction while maintaining a constant distance between them. Similarly, the operation unit 124 and the bed unit 106 are supported by the support unit 104 so as to be linked to each other in the vertical direction. The operation unit 124 and the bed unit 106 move in conjunction while maintaining a constant distance between them.

[0090] In other words, the support unit 104 is installed on the floor or ceiling and supports the operating unit 124 and the bed unit 106 so that they can move up and down. The support unit 104 supports the display unit 122 and the bed unit 106 so that they can move up and down. Note that the display unit 122 and the bed unit 106 do not move in conjunction with each other in the horizontal direction. Similarly, the operating unit 124 and the bed unit 106 do not move in conjunction with each other in the horizontal direction.

[0091] Figure 6 shows a configuration in which the operator 200 photographs the subject while seated. It is assumed that the operator 200 is seated on a chair 210 and operating the device near the center of the longitudinal direction of the bed section 106.

[0092] By moving the connecting section 112 downward from the configuration of the ultrasound diagnostic apparatus shown in Figure 5, and moving the panel unit 120 (display section 122 and operation section 124) and the patient bed section 106 downward, the ultrasound diagnostic apparatus becomes as shown in Figure 6. In the configuration of the ultrasound diagnostic apparatus shown in Figure 6, the distance between the patient bed section 106 and the floor surface is closer, and the distance between the patient bed section 106 and the frame section 140 is greater, compared to the configuration of the ultrasound diagnostic apparatus shown in Figure 5.

[0093] The operator 200 uses the ultrasonic transducer 144, which has descended from the frame section 140 (storage section for the ultrasonic transducer), and the control unit 124 to image the subject (not shown) placed on the bed section 106. The operator can place their knees under the bed section 106, thus eliminating the twisting posture of the waist.

[0094] In this way, even when the operator 200 is seated in the chair 210, the display unit 122, the control unit 124, the ultrasonic probe 144, and the patient bed 106 can be installed in front of the operator. Therefore, the operator 200 can perform imaging in a natural posture facing the subject.

[0095] The vertical drive of the components of the ultrasound diagnostic device will be explained using Figures 7A and 7B. Figures 7A and 7B are cross-sectional views of the ultrasound diagnostic device. The cross-sectional view of the ultrasound diagnostic device is a cross-sectional view taken along the center line (dotted line) extending in the vertical direction in Figure 2.

[0096] Figure 7A shows the configuration of the vertical drive unit (belt type) that moves components such as the bed section 106 and the panel unit 120 (display section 122, operation section 124) in the vertical direction.

[0097] The inside of the support section 104 is hollow. Inside the support section 104 are pulleys 202, 204 (multiple pulleys), and a belt 206. Pulleys 202 and 204 are rotating bodies. Pulleys 202 and 204 are spaced apart in the longitudinal direction of the support section 104. The tilt axis of pulley 202 and the rotation axis of pulley 204 are installed on the inner wall of the support section 104, respectively, and support pulleys 202 and 204 so that they can rotate. The rotation axes of pulley 202 and 204 are parallel to the horizontal plane. The belt 206 is wound around pulleys 202 and 204 (multiple pulleys) under tension. The belt 206 should preferably be made of a material that is resistant to slippage, such as a gear belt. Pulleys 202 and 204 have the function of transmitting power to belt 206.

[0098] When either pulley 202 or pulley 204 is rotated, belt 206 slides vertically (in the G direction).

[0099] Belt fixing parts 208 and 210 are installed on the surface of belt 206. Belt fixing parts 208 and 210 are fixed to belt 206 and connecting part 112. Belt fixing parts 208 and 210 and connecting part 112 are integrated. As a result, belt 206 and connecting part 112 become one unit.

[0100] Furthermore, the connecting section 112 is integrated with the bed section 106 via the sliding section 108. The connecting section 112 is integrated with the panel unit 120 (display section 122, operation section 124). Therefore, the belt 206 is integrated with the bed section 106 and the panel unit 120 (display section 122, operation section 124).

[0101] The motor drive of the drive unit 200 in the vertical drive unit rotates either the pulley 202 or the pulley 204, applying force to the belt 206. This causes the belt 206 to slide in the vertical direction (G direction), allowing the connecting unit 112 to move vertically. By moving the connecting unit 112 vertically, components such as the bed unit 106 and the panel unit 120 (display unit 122, operation unit 124) can be moved vertically (B direction, C direction).

[0102] Specifically, the motor drive of the drive unit 200 rotates the pulley 204 counterclockwise, and when the belt 206 in contact with the pulley 204 rotates counterclockwise, the belt fixing parts 208 and 210 move upward. When the belt fixing parts 208 and 210 move upward, the connecting part 112 can be moved upward, and components such as the bed section 106 and the panel unit 120 (display section 122, operation section 124) can be moved upward.

[0103] The motor drive of the drive unit 200 rotates the pulley 204 clockwise, and when the belt 206 in contact with the pulley 204 rotates clockwise, the belt fixing parts 208 and 210 move downward. When the belt fixing parts 208 and 210 move downward, the connecting part 112 can be moved downward, and components such as the bed section 106 and the panel unit 120 (display section 122, operation section 124) can be moved downward.

[0104] The distance between pulley 202 and pulley 204 is longer than the vertical stroke width of components such as the bed section 106 and the panel unit 120 (display section 122, operation section 124). The sliding width of the belt 206 is equal to the vertical stroke width of components such as the bed section 106 and the panel unit 120 (display section 122, operation section 124). If the belt 206 attempts to slide beyond its sliding width, the control unit 18 locks the sliding of the sliding section 206.

[0105] Thus, the support section 104 is equipped with an up-and-down drive unit (belt type) that moves the connecting section 112 in the vertical direction. As the connecting section 112 moves in the vertical direction, components such as the bed section 106 and the panel unit 120 (display section 122, operation section 124) can be moved in the vertical direction.

[0106] Figure 7B shows the configuration (rack and pinion system) of the vertical drive unit that moves components such as the bed section 106 and the panel unit 120 (display section 122, operation section 124) up and down. The inside of the support section 104 is hollow. Inside the support section 104 are a circular gear 220 and a gear support section 222 that rotatably supports the circular gear 220. The gear support section 222 is fixed to the connecting section 112, and the gear support section 222 and the connecting section 112 are integrated.

[0107] Furthermore, the connecting section 112 is integrated with the bed section 106 via the sliding section 108. The connecting section 112 is integrated with the panel unit 120 (display section 122, operation section 124). Therefore, the circular gear 220 and the gear support section 222 are integrated with the bed section 106 and the panel unit 120 (display section 122, operation section 124).

[0108] The gear support section 222 supports the circular gear 220 so that its axis of rotation is parallel to the horizontal plane. The circular gear 220 can be rotated by motor drive. Inside the support section 104 is a drive unit 200 that rotates the circular gear 220 by motor drive.

[0109] Furthermore, a flat rod member 226 and a rod member support part 224 that supports the rod member 226 are installed inside the support part 104. The rod member support part 224 is inscribed within the support part 104 and is fixed to the support part 104. The flat rod member 226 is installed along the longitudinal direction (vertical direction) of the support part 104. The longitudinal direction of the support part 104 is perpendicular to the horizontal plane.

[0110] The surface of the rod member 226 has an uneven surface that matches the gear shape of the circular gear 220.

[0111] The circular gear 220 and the rod member 226 mesh with each other. When the drive unit 200 applies rotational force to the circular gear 220, the circular gear 220 rolls on the surface of the rod member 226, causing the connecting part 112 to move vertically (direction H). In other words, the drive unit 200 can move the circular gear 220 vertically. By moving the connecting part 112 vertically, components such as the bed section 106 and the panel unit 120 (display section 122, operation section 124) can be moved vertically (direction B, direction C).

[0112] Specifically, when the drive unit 200 in the vertical drive unit rotates the circular gear 220 clockwise, the circular gear 220 rolls along the longitudinal direction of the rod member 226 and moves downward. When the circular gear 220 moves downward, the connecting unit 112 can be moved downward, and components such as the bed unit 106 and the panel unit 120 (display unit 122, operation unit 124) can be moved downward.

[0113] On the other hand, when the drive unit 200 rotates the circular gear 220 counterclockwise, the circular gear 220 rolls along the longitudinal direction of the rod member 226 and moves upward. When the circular gear 220 moves upward, the connecting part 112 can be moved upward, and components such as the bed section 106 and the panel unit 120 (display section 122, operation section 124) can be moved upward.

[0114] While the vertical drive system of the present invention has shown examples such as a belt system and a rack and pinion system as described above, other forms such as a gear system and a combination of a cam follower and a guide rail may also be used.

[0115] Figures 8 and 9 show the configuration of the frame portion 140 in the ultrasound diagnostic apparatus of the present invention.

[0116] As shown in Figure 8, the support section 104 supports the frame section 140 at its uppermost position. The frame section 140 does not move vertically. The frame section 140 houses the ultrasonic probes 142 and 144. In addition to housing the ultrasonic probes, the frame section 140 also has an emergency stop button 300, projection sections 302 and 304, cameras 306 and 308, and a sensor 310.

[0117] The emergency stop button 300 is a button that stops the operation of the components of the ultrasound diagnostic device. When components such as the patient bed 106 and the panel unit 120 (display unit 122, operation unit 124) are moving vertically using the drive unit 200, there is a risk that the patient placed on the patient bed 106 may come into contact with the components of the ultrasound diagnostic device (for example, the display unit 122 and the operation unit 124).

[0118] At this time, the operator can stop the operation of the components of the ultrasound diagnostic device by pressing the emergency stop button 300. Specifically, the emergency stop button 300 is connected to the control unit 18. When the emergency stop button 300 is pressed, the fact that the emergency stop button 300 has been pressed (stop signal) is transmitted to the control unit 18. The control unit 18 stops the motor drive of the drive unit 200 and stops the vertical movement of the coupling unit 112. As a result, the movement of components such as the patient bed 106 and the panel unit 120 (display unit 122, operation unit 124) is stopped.

[0119] In this way, the emergency stop button 300 makes it possible to avoid the risk of the patient coming into contact with the components of the ultrasound diagnostic device.

[0120] Although the control of the drive unit 200 was described as an example of stopping the operation of the components of the ultrasound diagnostic device, the control unit 18 may also stop the transmission and reception of ultrasound in the ultrasound probe 144 by pressing the emergency stop button 300.

[0121] The frame section 140 has cameras 306 and 308, which mainly photograph the subject placed on the bed section 106. The control unit 18 can display the images captured by cameras 306 and 308 on the display unit 122. Cameras 306 and 308 may be depth cameras that acquire depth information (vertical direction) of the subject placed on the bed section 106.

[0122] Cameras 306 and 308 are arranged in parallel. The control unit 18 processes the images acquired from the two cameras to measure the depth information of the subject. For example, in the stereo camera system, the depth information of the subject is measured from the parallax information of each camera 306 and camera 308. In the ToF (Time of Flight) camera system, near-infrared light is emitted from either camera 306 or camera 308 towards the subject, and the depth information of the subject is measured by measuring the time it takes for the reflected wave to arrive. The control unit 18 can acquire three-dimensional information, including the depth information of the subject, using cameras 306 and 308. By understanding the depth information of the subject, the control unit 18 can set the amount (length) of cable 146 of the ultrasonic probe 144 used for imaging to be pulled out.

[0123] Furthermore, the control unit 18 can acquire various information about the subject using camera recognition technology. For example, the control unit 18 can acquire the subject's physique, the location of the organs in contact with the ultrasound probe 144 (imaging area), and so on. The control unit 18 can also associate the ultrasound image generated by the ultrasound image generation unit 16 with the subject's depth information, the subject's physique, and the imaging area. The storage unit 20 can store the ultrasound image in association with the subject's depth information, the subject's physique, and the imaging area.

[0124] The projection units 302 and 304 project images onto the bed unit 106, or onto the subject placed on the bed unit 106.

[0125] Projection units 302 and 304 each have, for example, a light source lamp and a lens. Projection units 302 and 304 decompose the light source lamp into the three primary colors of light: red, green, and blue. Then, projection units 302 and 304 generate images of each color using a transmissive panel and project them through the lens.

[0126] The images projected from projection units 302 and 304 may include the position information of the ultrasonic transducer 144 from the previous image capture. Specifically, cameras 306 and 308 are connected to the control unit 18. Cameras 306 and 308 capture images of the ultrasonic transducer 144 in contact with the patient, and the control unit 18 analyzes the images acquired from cameras 306 and 308. The control unit 18 acquires the position information of the ultrasonic transducer 144 from the analyzed images. The storage unit 20 stores the position information of the ultrasonic transducer 144. Projection units 302 and 304 acquire the position information of the ultrasonic transducer 144 stored in the storage unit 20 and project the position information of the ultrasonic transducer 144 onto the patient placed on the examination table 106. By confirming the position information of the ultrasonic transducer 144 from the previously captured image in the projected image, the operator can bring the ultrasonic transducer 144 into contact with the same position and take an image. Therefore, the operator can check the changes over time from the previous and current ultrasound image data.

[0127] Two projection units, a projection unit 302 and a projection unit 304, are installed in the frame unit 140. By combining the images projected from projection unit 302 and projection unit 304, the image projected onto the examination bed unit 106, or onto the subject placed on the examination bed unit 106, can be displayed in a larger size.

[0128] Furthermore, the content projected from projection unit 302 and projection unit 304 can be different. For example, an image can be projected from one projection unit, while explanatory text can be projected from the other.

[0129] Furthermore, projection units 302 and 304 can also function as lighting units to illuminate the examination table 106. Examination rooms where ultrasound diagnostic equipment is installed are dark, and it can be difficult for patients to recognize the ultrasound diagnostic equipment. By illuminating the examination table 106 with projection units 302 and 304, patients can easily recognize the ultrasound diagnostic equipment. In addition, by illuminating the examination table 106 with projection units 302 and 304, the floor surface near the ultrasound diagnostic equipment becomes brighter, which can help prevent tripping by operators or patients.

[0130] The illumination light can also be set by combining red, green, and blue light from the light sources of projection units 302 and 304. Furthermore, projection units 302 and 304 can be equipped with a function to narrow the illumination field so that the illumination light does not enter the subject's face.

[0131] Sensor 310 is, for example, a human presence sensor that can detect the presence or absence of an operator near the ultrasound diagnostic device and the presence or absence of a patient placed on the bed 106. Sensor 310 and the control unit 18 are connected, and information on the presence or absence of an operator or patient is transmitted to the control unit 18. The control unit 18 can perform various controls depending on the presence or absence of an operator or patient. For example, if an operator approaches the ultrasound diagnostic device patient, the control unit 18 activates projection units 302 and 304 as illumination units. Also, if a patient is placed on the bed 106, the control unit 18 restricts the vertical movement of the vertical drive unit described above.

[0132] As shown in Figure 8, the frame 140 is equipped with a storage section for housing multiple ultrasonic probes 142 and 144. The storage section for the ultrasonic probes in the frame 140 is located above the bed 106. In other words, the storage section for the ultrasonic probes is located at a higher position than where the bed 106 is installed. Furthermore, the storage section for the ultrasonic probes is located above the operation unit 124 or the display unit 122. In other words, the storage section for the ultrasonic probes is located at a higher position than where the operation unit 124 or the display unit 122 is installed.

[0133] Multiple ultrasonic probes 142 and 144 are installed and housed side by side in the frame 140. The multiple ultrasonic probes 142 and 144 are installed and housed side by side in a direction parallel to the shorter side of the patient bed 106. The multiple ultrasonic probes 142 and 144 are housed at equal intervals so as not to come into contact with each other. Since the multiple ultrasonic probes 142 and 144 are installed side by side in the frame 140, even if the ultrasonic probe 144 used for imaging is lowered from the frame 140, the cables of each ultrasonic probe will not become entangled. Also, since the ultrasonic probe 144 is suspended from the frame 140, the cable 146 of the ultrasonic probe 144 is installed above the ultrasonic probe 144. In other words, the cable 146 is installed at a higher position than where the ultrasonic probe 144 is installed. Although the ultrasonic probe 144 comes into contact with the subject, if the cable 146, which is installed above the ultrasonic probe 144, is not flexed, the cable 146 will not come into contact with the subject. Therefore, the cable 146 can be kept in a hygienic condition.

[0134] Figure 9 is a cross-sectional view of the frame portion 140, showing the configuration of the ultrasonic probe housing. Here, the housing configuration for ultrasonic probe 144 is shown, but the other ultrasonic probes 142 have a similar housing configuration.

[0135] As shown in Figure 9, a hole 152 is formed on the lower surface of the frame portion 140. The cable 146 of the ultrasonic probe 144 is placed in the hole 152. The frame portion 140 has a winding section 148 for winding the cable 146 of the ultrasonic probe 144 and a drive section 150 for driving the winding section 148.

[0136] The cable 146 is wound around the winding section 148. The rotation axis of the winding section 148 is installed on the inner wall of the frame section 140, and supports the winding section 148 so that it can rotate. The rotation axis of the winding section 148 is parallel to the horizontal plane.

[0137] The motor drive of the drive unit 150 rotates the winding unit 148, allowing the cable 146 to move vertically (in the F direction). As a result, the ultrasonic probe 144 can be moved vertically.

[0138] When the drive unit 150 rotates the winding unit 148 clockwise, the cable 146 is pulled out, and the ultrasonic probe 144 can be lowered downwards. The operator can then take images with the ultrasonic probe 144 that has been lowered downwards.

[0139] The amount of rotation (clockwise) of the winding unit 148 corresponds to the length of the cable 146 to be pulled out. The amount of rotation of the winding unit 148 may be preset in the drive unit 150. The control unit 18 can preset the amount of rotation (clockwise) of the winding unit 148 to the drive unit 150 so that the length of the cable 146 from the frame unit 140 is a predetermined length (for example, 100 cm).

[0140] When the drive unit 150 rotates the winding unit 148 counterclockwise, the cable 146 is pulled back, and the ultrasonic probe 144 is moved upward. The amount of rotation of the winding unit 148 when pulled back (counterclockwise) is equivalent to the amount of rotation of the winding unit 148 when pulled out (clockwise).

[0141] In this way, the operator can store the ultrasonic probe 144.

[0142] The operator can select the ultrasonic probe to be used for imaging from among the multiple ultrasonic probes 142 housed in the frame 140 (storage section for ultrasonic probes). Once the operator has selected the ultrasonic probe to be used for imaging, the control unit 18 controls the drive unit 150 to rotate the winding section 148 corresponding to the selected ultrasonic probe 144 clockwise. The selected ultrasonic probe 144 then descends from the frame 140.

[0143] The control unit 18 can also be set to select an ultrasonic probe 144 that matches the examination area or imaging conditions of the subject and to descend from the frame 140. When imaging a desired area (first area) of the subject, the control unit 18 controls the drive unit 150 that moves the ultrasonic probe up and down to image the desired area (first area). When imaging a desired area (second area) of the subject, the control unit 18 controls the drive unit 150 that moves the ultrasonic probe up and down to image the desired area (second area). Furthermore, when imaging the subject under desired imaging conditions (first imaging conditions), the control unit 18 controls the drive unit 150 that moves the ultrasonic probe up and down to image the subject under desired imaging conditions (first imaging conditions). Furthermore, when imaging the subject under desired imaging conditions (second imaging conditions), the control unit 18 controls the drive unit 150 that moves the ultrasonic probe up and down to image the subject under desired imaging conditions (second imaging conditions).

[0144] For example, when imaging the carotid artery of a subject, the control unit 18 controls the winding unit 148 to rotate clockwise in relation to the drive unit 150, which moves the linear ultrasonic probe up and down. In this way, the cable of the linear ultrasonic probe is pulled out, and the linear ultrasonic probe descends from the frame unit 140. At this time, the illumination unit (LED) installed inside the linear ultrasonic probe can be lit to inform the operator that the linear ultrasonic probe has been selected.

[0145] When imaging the patient's abdomen, the control unit 18 controls the drive unit 150, which moves the convex-type ultrasonic probe up and down, to rotate the winding unit 148 clockwise. In this way, the cable of the convex-type ultrasonic probe is pulled out, and the convex-type ultrasonic probe descends from the frame unit 140. At this time, the illumination unit (LED) installed inside the convex-type ultrasonic probe can be illuminated to inform the operator that the convex-type ultrasonic probe has been selected.

[0146] When imaging the patient's heart, the control unit 18 controls the drive unit 150, which moves the sector-type ultrasound probe up and down, to rotate the winding unit 148 clockwise. In this way, the cable of the sector-type ultrasound probe is pulled out, and the sector-type ultrasound probe descends from the frame unit 140. At this time, the illumination unit (LED) installed inside the sector-type ultrasound probe can be illuminated to inform the operator that the sector-type ultrasound probe has been selected.

[0147] The ultrasonic transducer 144 that has descended from the frame 140 may be performing ultrasonic transmission and reception so that the subject can be photographed immediately. The operator can use the ultrasonic transducer 144 that has descended from the frame 140 to photograph the subject placed on the examination table 106.

[0148] The winding unit 148 may utilize a spring (not shown) installed inside the winding unit 148. When the cable 146 is pulled out, the drum rotates and the spring is wound up. The ultrasonic probe 144 and the cable 146 are then pulled out from the frame unit 140.

[0149] The spring has the property of returning to its original state. The cable 146 returns to the hole 152 and is wound onto the winding section 148, but a brake (not shown) suppresses the rotation of the drum and prevents the cable 146 from returning. With the ultrasonic probe 144 and cable 146 pulled out from the frame section 140, the operator uses the ultrasonic probe 144 to take images of the subject.

[0150] After photographing the subject, the operator releases the brake. When the brake is released, the spring returns to its original state, causing the drum to rotate and the cable 146 to be wound up. In this way, the ultrasonic probe 144 and the cable 146 are housed in the frame 140.

[0151] Furthermore, if the desired ultrasonic probe is not among the multiple ultrasonic probes 142 housed in the frame section 140 (storage section for ultrasonic probes), the ultrasonic probe can be replaced. Specifically, a connector section (not shown) is installed at the end of the cable 146, and the ultrasonic probe 144 and the cable 146 can be separated.

[0152] The connector is a component for connecting the ultrasonic probe 144 to the ultrasonic diagnostic device. The connector has terminals that engage with the ultrasonic probe 144. By connecting the ultrasonic probe 144 and the cable 146 via the connector, the ultrasonic probe 144 can be connected to the transmitting / receiving unit 12 in the device body 10. Furthermore, by connecting the cable 146 to another ultrasonic probe via the connector, other ultrasonic probes can be connected to the transmitting / receiving unit 12 in the device body 10.

[0153] Here, we have described the ultrasonic probe 144 and cable 146, but other ultrasonic probes and cables have a similar configuration. In this way, by changing the ultrasonic probe, it is possible to install various ultrasonic probes, such as radial probes and endoscopic probes, which are not shown in Figure 8.

[0154] Although each of the ultrasonic probes 142 and 144 had a cable, they may also be wireless ultrasonic probes. A wireless ultrasonic probe has a wireless transmitter, a wireless receiver, a battery, etc. Wireless communication between the wireless ultrasonic probe and the main unit 10 can be performed by the wireless transmitter and wireless receiver.

[0155] Furthermore, the wireless ultrasonic probe can be fitted into the hole 152 of the frame 140.

[0156] Furthermore, the frame portion 140 has a function for charging the battery of the wireless ultrasonic probe.

[0157] Furthermore, the frame 140 may be fitted with a display unit 312 for displaying ultrasound images. The display unit 312 is detachable from the frame 140. The display unit 312 is connected to the main body 10 of the device. The display unit 312 can display ultrasound images generated by the ultrasound image generation unit 16. The display surface of the display unit 312 faces downwards and towards the patient who is placed on the bed 106. The patient can view the display unit 312 while lying on their back. In other words, the patient can view the display unit 312 in a natural position without changing their posture. The patient can check their medical condition and the condition of the fetus from the ultrasound image data. The operator can explain the medical condition and the condition of the fetus while the patient is placed on the bed 106.

[0158] Figure 10 shows the configuration of the operating unit 124 in the ultrasound diagnostic apparatus of the present invention.

[0159] The control unit 124 has a freeze button 502 for freezing the ultrasound image displayed on the display unit 122. The freeze button 502 on the control unit 124 is a button used to freeze (stop) the ultrasound image displayed in real time when saving it. When the operator presses the freeze button 502 while the ultrasound probe 144 is not moving, the ultrasound image displayed in real time on the display unit 122 can be frozen. The data of the frozen ultrasound image can be stored in the storage unit 20.

[0160] The control unit 124 has a trackball 504. By operating the trackball 504, the operator can move the measuring caliper or move various commands.

[0161] The control unit 124 has a trackball 504 at its center, with switch groups 506-510 arranged in an arc. Switch groups 506-510 consist of a B-mode switch for selecting B-mode as the ultrasound imaging method, a CFM-mode switch for selecting CFM-mode, a Doppler-mode switch for selecting Doppler-mode, and an M-mode switch for selecting M-mode. When a button in switch group 506-510 is selected, it is illuminated by an LED or the like. The operator can then be aware that a button has been selected.

[0162] The operating unit 124 has a handle 520 for the operator to grip. The operator can move the operating unit 124 by gripping the handle 520. For example, as shown in Figure 1, the operating unit 124 can be pulled out from the panel unit 120, or as shown in Figure 3, it can be stored in the panel unit 120.

[0163] The handle 520 has an upward slope relative to the upper surface of the control unit 124 and also functions as a palm rest. The user can operate the freeze button 502, trackball 504, and switch groups 506-510 while resting their palms on the handle 520.

[0164] The control unit 124 has a screen 530. The screen 530 displays the selected mode, patient information, etc., via the switch groups 506 to 510.

[0165] Figures 11 and 12 show modified examples of the patient bed 106 in the ultrasound diagnostic apparatus of the present invention.

[0166] As shown in Figure 11, the bed section 106 consists of a first frame 450 that supports the subject's waist, a second frame 452 that supports the subject's upper body, and a third frame 454 that supports the subject's lower body.

[0167] A tilt axis is installed between the first frame 450 and the second frame 452. In other words, a tilt axis is installed in the dividing groove 420. The tilt axis between the first frame 450 and the second frame 452 is parallel to the horizontal plane and parallel to the short side of the bed section 106.

[0168] A drive unit is installed inside the bed section 106 (dividing groove 420). The motor drive of the drive unit allows the second frame 452 to rotate in a predetermined rotational direction (direction I) around the tilt axis. The operator can rotate the second frame 452 and tilt it upward. By tilting the second frame 452 upward, the upper body of the patient can be raised.

[0169] A tilt axis is installed between the first frame 450 and the third frame 454. In other words, a tilt axis is installed in the dividing groove 422. The tilt axis between the first frame 450 and the third frame 454 is parallel to the horizontal plane and parallel to the short side of the bed section 106.

[0170] A drive unit is installed inside the bed section 106 (dividing groove 422). The motor drive of the drive unit allows the third frame 454 to rotate in a predetermined rotational direction (J direction) around the tilt axis. The operator can rotate the third frame 454 around the tilt axis and tilt the third frame 454 downward. By tilting the third frame 454 downward, the lower body of the patient can be lowered.

[0171] As shown in Figure 11, the bed section 106 can recline and take on a chair-like shape. The operator can use an ultrasound probe to image the patient while the bed section 106 is reclined.

[0172] Furthermore, as shown in Figure 11, the patient can lie on the bed 106 when it is reclined (with a backrest). The ultrasound diagnostic device can also be changed from the state shown in Figure 11 to the state shown in Figure 1, and the bed 106 can be made horizontal. Specifically, the operator rotates the second frame 452 to make it horizontal, and rotates the third frame 454 to make it horizontal. In this way, the bed 106 can be made horizontal, and the operator can take images of the patient with the bed 106 in a horizontal position. In addition, as described above, the operator can move the bed 106, the panel unit 120 (display unit 122, operation unit 124), and other components in the vertical direction (direction B, direction C) by moving the connecting unit 112 in the vertical direction.

[0173] When the subject gets off the bed 106, the operator reclines the bed 106 (with the backrest up), as shown in Figure 11. This makes it easier for the subject to get on and off the bed 106.

[0174] Figure 12 shows a configuration in which the reclining direction of the bed section 106 shown in Figure 11 is different.

[0175] In the configuration of the bed section 106 shown in Figure 11, the second frame 452 supported the upper body of the subject, but in the configuration of the bed section 106 shown in Figure 12, the second frame 452 supports the lower body of the subject. Also, in the configuration of the bed section 106 shown in Figure 11, the third frame 454 supported the lower body of the subject, but in the configuration of the bed section 106 shown in Figure 12, the third frame 454 supports the upper body of the subject.

[0176] The motor drive unit allows the second frame 452 to rotate in a predetermined rotational direction (direction I). As shown in Figure 12, the operator can rotate the second frame 452 and tilt it downwards. By tilting the second frame 452 downwards, the lower body of the subject can be lowered.

[0177] Furthermore, the motor drive of the drive unit allows the third frame 454 to be rotated in a predetermined rotational direction (direction J). As shown in Figure 12, the operator can rotate the third frame 454 and tilt it upward. By tilting the third frame 454 upward, the upper body of the subject can be raised.

[0178] Furthermore, in the configuration of the panel unit 120 shown in Figure 11, the operating section 124 for the operator was located on the left side, while the probe holder 126, the bottle storage section 128, and the tissue paper box 130 were located on the right side.

[0179] The control unit 124 is detachable from the panel unit 120. As shown in Figure 12, the control unit 124 can also be installed on the right side of the panel unit 120. Similarly, the probe holder 126, bottle storage unit 128, and tissue paper box 130 are detachable from the panel unit 120. As shown in Figure 12, the probe holder 126, bottle storage unit 128, and tissue paper box 130 can also be installed on the left side of the panel unit 120.

[0180] Furthermore, in the configuration of the frame 140 shown in Figure 11, multiple ultrasonic probes 142 were housed on the right side. The ultrasonic probe housing is detachable from the frame 140.

[0181] As shown in Figure 12, the ultrasonic probe housing can also be installed on the left side of the frame 140.

[0182] As described above, the ultrasound diagnostic apparatus of the present invention comprises an operating unit 124 having multiple input elements and inputting at least ultrasound-related information, a patient bed 106 on which a patient is placed, and a support unit 104 that supports the operating unit 124 and the patient bed 106 so that the operating unit 124 is positioned above the patient bed 106. The operating unit 124 is positioned higher than the position on which the patient bed 106 is installed.

[0183] Since the control unit 124 is installed above the bed section 106, the operator can perform the imaging in a natural posture facing the subject placed on the bed section 106, while also operating the control unit 124.

[0184] Furthermore, the ultrasound diagnostic apparatus of the present invention includes a display unit 122 that displays an ultrasound image based on ultrasound transmitted and received using an ultrasound transducer that transmits and receives ultrasound to and from a patient, and the support unit 104 supports the display unit 122 and the patient bed 106 so that the display unit 122 is positioned above the patient bed 106.

[0185] In the ultrasound diagnostic apparatus of the present invention, the support unit 104 supports the operation unit 124 and the patient bed unit 106 so that they can move up and down, and also supports the display unit 122 and the patient bed unit 106 so that they can move up and down.

[0186] The ultrasound diagnostic apparatus of the present invention includes a storage section (frame section 140) for housing a plurality of ultrasound probes. The support section 104 supports the storage section (frame section 140).

[0187] A computer program that implements the control functions (including various drives) of the ultrasound diagnostic apparatus of the present invention can be supplied to the computer (control unit 18) of the ultrasound diagnostic apparatus via a network or storage medium (not shown), and the computer program can be executed.

[0188] The computer program is a program that enables the computer (control unit 18) to implement the functions of the ultrasound diagnostic device. The storage medium stores this computer program.

[0189] The present invention is not limited to the embodiments described above, and various modifications and variations are possible without departing from the spirit and scope of the invention. Accordingly, the following claims are attached to make the scope of the invention public.

[0190] This application claims priority based on Japanese Patent Application No. 2021-157066, filed on September 27, 2021, and all of its contents are incorporated herein by reference.
