DETAILED DESCRIPTION OF THE INVENTION

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The present invention will be described in detail below with reference to the accompanying drawings. Note that the present invention is not limited to the present embodiment. Fig. 1 is a diagram showing a medical bed mat according to this embodiment.

[0023] The medical bed mat 10 according to this embodiment is provided on a bed of a medical imaging inspection device such as CT (Computed Tomography), MRI (Magnetic Resonance Imaging), an X-ray inspection device, or PET (Positron Emission Tomography).

[0024] The medical bed mat 10 is placed on a bed 12 of a medical imaging examination apparatus and includes a holder 18 for positioning and fixing the top plate 14 of the bed 12 and the subject 16 relative to the medical imaging examination apparatus and for ensuring the safety of the subject 16. A pair of holders 18 are provided to abut on both sides of the subject 16. The subject 16 can be held by moving the holders 18 in the direction of arrow X in FIG. 1 and fixing the holders 18 with a fixing belt 20 or the like relative to the subject 16 placed on the medical bed mat 10. The holders 18 may be mesh-like for comfort. The holders 18 may be made of a sweat-absorbent material (e.g., cotton, linen, or a combination of cotton and linen), or may be made of a sweat-resistant, quick-drying material (e.g., polyester) to prevent staining. The color of the holders is preferably a color that is easily distinguishable from the subject 16 (e.g., black, blue, etc.).

[0025] 1, the holder 18 may be a sheet-like member, and may hold the subject 16 together with its arms to immobilize the subject. If the subject 16's arms are wrapped in the holder 18, it may be difficult to check the state of the subject 16, and it may be difficult to check whether the subject is being held and immobilized appropriately.

[0026] Therefore, the medical bed mat 10 according to this embodiment has an optically transparent or translucent portion 18A in at least a portion of at least one of the pair of holding portions 18. The transparent or translucent portion 18A of the holding portion 18 may be colored. For example, it may be transparent and colored in a color that is easily recognized by a camera (e.g., a light color such as light blue or yellow).

[0027] Note that optically transparent or translucent means that the body of the subject 16 held by the holding portion 18 of the medical bed mat 10 and the state in which the body is held are transparent enough to be visible to an operator such as a technician. For example, the total light transmittance measured in accordance with "ISO 13468-1" may be 50% or more. Furthermore, the total light transmittance is more preferably 70% or more, and even more preferably 85% or more. The higher the total light transmittance, the more the visibility of the body of the subject 16 can be improved. The method for measuring total light transmittance is not limited to "ISO 13468-1" (corresponding to JIS K 7361-1), and other measurement methods such as "JIS K 7375" can also be used.

[0028] In this embodiment, the holding unit 18 is provided with a marking 22 as an example of a mark. By checking the marking 22, it is possible to check the holding state by the holding unit 18. The marking 22 may be provided on the transparent or semi-transparent portion 18A of the holding unit 18, or the transparent or semi-transparent portion 18A and the marking 22 may be located in different positions. The marking 22 may also be used as a reference for alignment in scanography or the like.

[0029] FIG. 2 is a diagram showing an example of the marking 22 provided on the holding portion 18 of the medical bed mat 10 according to this embodiment.

[0030] The markings 22 are provided at multiple positions on the holder 18, as shown in FIG. 2, and may have various shapes. For example, the markings 22 may be in the form of a circle, triangle, square, or other shape, or may be a combination of multiple circles, triangles, squares, or other shapes. Alternatively, the markings 22 may be numbers or letters. Alternatively, the markings 22 may be rectangular shapes whose short sides are aligned with the body axis direction of the subject 16 (the horizontal direction in FIG. 2), or triangular shapes whose long sides are aligned with the direction perpendicular to the body axis direction of the subject 16 (the vertical direction in FIG. 2) or with the body axis direction of the subject 16 (the horizontal direction in FIG. 2). The shapes may be filled in with a predetermined color or may be hatched. The markings 22 may also be one-dimensional or two-dimensional barcodes.

[0031] The position of the marking 22 may be changeable relative to the holding portion 18. For example, the marking 22 may be movable on a fastener-like rail, or may be detachable using Velcro (registered trademark), buttons, or the like.

[0032] Next, a medical image inspection system according to this embodiment will be described. Fig. 3 is a block diagram showing the schematic configuration of the medical image inspection system according to this embodiment.

[0033] As shown in FIG. 3, a medical image inspection system 30 according to this embodiment includes a medical image inspection device 32 and a console .

[0034] The medical imaging inspection device 32 may be any of various medical imaging inspection devices, and captures images of the inside of the body of the subject 16. For example, a CT, an MRI, an X-ray detection device, a PET, etc. may be used. For example, in the case of a CT or an X-ray detection device, radiation is irradiated onto the subject 16 to obtain a radiological image, and in the case of an MRI, a magnet and electromagnetic waves are used on the subject 16 to obtain a magnetic resonance image.

[0035] The console 34 has a function of controlling the medical imaging inspection device 32 using imaging orders and various information acquired from a RIS (Radiology Information System) 36 or the like via a wireless communication LAN (Local Area Network) or the like, and instructions given by a user via an operation unit 32C (see FIG. 4) or the like. The console 34 is also connected to an image storage system 38 via wireless communication or wired communication, and has a function of transmitting various images acquired by the medical imaging inspection device 32 to the image storage system 38 such as a PACS (Picture Archiving and Communication Systems) for storage.

[0036] 4 shows a block diagram illustrating an example of the configuration of the main parts of the medical image inspection device 32 and the console 34. Note that the main parts of the medical image inspection device 32 and the console 34 have a general computer configuration, so the medical image inspection device 32 will be described as a representative example.

[0037] As shown in FIG. 4, the medical image inspection device 32 includes a control unit 32A, a display unit 32B, an operation unit 32C, a detection unit 32D, and a communication I / F (interface) unit 32E.

[0038] The control unit 32A controls the overall operation of the medical image inspection device 32. The control unit 32A includes a CPU 32F, a ROM 32G, and a RAM 32I. The ROM 32G stores in advance various programs 32H executed by the CPU 32F, such as an imaging processing program and a display processing program executed when controlling imaging. The RAM 32I temporarily stores various data.

[0039] The display unit 32B displays a screen for operating the medical image inspection device 32, the detection results of the detection unit 32D, captured radiological images, magnetic resonance images, etc. A direct-view electronic display, for example, is used as the display unit 32B.

[0040] The operation unit 32C is used by the user to input instructions related to photography, various information, etc. The operation unit 32C is not particularly limited, and examples thereof include various switches, a touch panel, a touch pen, and a mouse.

[0041] The detector 32D detects the marking 22 provided on the holder 18 of the medical bed mat 10. The detector 32D may be, for example, an optical imaging device such as a camera or an infrared camera, a photosensor such as a reflective photointerrupter, or a barcode sensor. Multiple detectors 32D may be provided, for example, on the ceiling or wall of the examination room, or on the housing of the medical imaging inspection device 32. Alternatively, the detectors 32D may be mounted on a mobile cart, a portable tripod, or a table so that they can be moved to an appropriate position around the bed. By providing multiple detectors on the ceiling, it becomes easier to detect whether the positional relationship between the subject 16 and the bed mat is appropriate from the top of the bed. By providing multiple detectors around the bed, such as on the left and right sides of the bed, it becomes easier to detect whether the positional relationship between the subject 16 and the medical bed mat 10 is appropriate at multiple locations on the left and right sides of the body axis or in the body axis direction. Furthermore, by installing it on a mobile cart, portable tripod, or table and making it movable, it becomes easier to determine whether the positional relationship between the subject and the bed mat is appropriate, taking into account the size of the subject and avoiding obstacles.

[0042] The communication I / F unit 32E communicates captured images (for example, radiographic images, magnetic resonance images, etc.) and various information with an external device such as the console 34 via wireless or wired communication.

[0043] In this embodiment, the control unit 32A detects the markings 22 on the medical bed mat 10 and notifies the detection result of the markings 22. For example, the control unit 32A determines whether the state of the detected markings 22 is a predetermined state and notifies the determination result as the detection result of the markings 22. When an optical imaging device such as a camera is used as the detection unit 32D, the control unit 32A may detect the markings 22 and the subject 16 using the captured image and determine whether the positional relationship between the markings 22 and the subject 16 is within a predetermined range, thereby determining whether the predetermined state is met. Specifically, the control unit 32A detects the positional relationship between the markings 22 and the subject 16 based on the detection result of the markings 22 by the detection unit 32D, thereby determining whether the medical bed mat 10 is set to properly support the subject 16. For example, the control unit 32A determines whether the state of the markings 22 detected by the detection unit 32D is a predetermined state and notifies the determination result by, for example, displaying it on the display unit 32B.

[0044] Here, an example of a method for determining whether the medical bed mat 10 is set so as to properly hold the subject 16 when an optical imaging device or a sensor is used as the detection unit 32D will be described with reference to Fig. 5. Fig. 5 is a diagram for explaining an example of a method for determining whether the medical bed mat 10 is set so as to properly hold the subject 16 when an optical imaging device or a sensor is used as the detection unit 32D. The example of Fig. 5 shows an example in which an arrangement of three circles is arranged at multiple positions (five locations) as the markings 22.

[0045] The control unit 32A detects the markings 22 at multiple positions using the detection unit 32D and determines whether the state of the markings 22 is a predetermined state. For example, based on the number of detected circles on each marking 22, the control unit 32A determines whether the medical bed mat 10 is set to properly support the subject 16. The control unit 32A then notifies the user of the determination result by displaying it on the display unit 32B or the like.

[0046] 5, when all the circles of all the markings 22 at multiple positions are detected by the detection unit 32D, the control unit 32A determines that the medical bed mat 10 is adequately supporting the subject 16. Then, a message such as "The medical bed mat has been set up properly" is displayed on the display unit 32B or output as audio to notify the user.

[0047] 5, if one or two circles are detected on the markings 22 at all or some of the positions, i.e., if three circles are not detected at all positions, the control unit 32A determines that the subject is not being held sufficiently by the medical bed mat 10. Then, a message such as "The medical bed mat is not set up properly" is displayed on the display unit 32B or output as audio to notify the user.

[0048] 5, if there is a large variation in the number of circles on the markings 22 detected by the detection unit 32D at each position, the control unit 32A determines that there is a portion where the medical bed mat 10 is not sufficiently supporting the subject 16. Then, a message such as "The medical bed mat is not set up properly" is displayed on the display unit 32B or output as audio to notify the user.

[0049] Next, an example of a method for determining whether the medical bed mat 10 is set to properly hold the subject 16 when an optical imaging unit is used as the detection unit 32D will be described. Fig. 6 is a diagram for explaining an example of a method for determining whether the medical bed mat 10 is set to properly hold the subject 16 when an optical imaging unit is used as the detection unit 32D. The example in Fig. 6 shows an example in which rectangular markings 22, whose short sides are aligned in the body axis direction of the subject 16, are arranged in multiple positions (five locations).

[0050] The control unit 32A detects the positional relationship between the subject 16 and the medical bed mat 10 from the captured image taken by the optical imaging unit serving as the detection unit 32D, and determines whether the positional relationship is a predetermined one. The control unit 32A also detects the markings 22 from the captured image, and determines whether the medical bed mat 10 is set to properly support the subject 16 based on the detection result of the markings 22. The control unit 32A then notifies the user of the determination result by displaying it on the display unit 32B or the like.

[0051] Specifically, the control unit 32A extracts the subject 16 and the markings 22 from the captured image captured by the optical imaging unit serving as the detection unit 32D, reads the position and height of the subject 16, determines whether the positional relationship between the subject 16 and the markings 22 is within a predetermined range, and notifies the determination result.

[0052] 6, when all the markings 22 at multiple positions are properly detected by the detection unit 32D, the control unit 32A determines that the subject 16 is properly covered by the medical bed mat 10 and that the medical bed mat 10 is adequately supporting the subject 16. Then, a message such as "The medical bed mat has been properly set up" is displayed on the display unit 32B or output as audio to notify the user.

[0053] 6, if the number of detected markings 22 is extremely small (for example, the length of the markings 22 in the longitudinal direction is equal to or less than a predetermined value), the control unit 32A determines that a large portion is not covered by the medical bed mat 10 and that the medical bed mat 10 is not adequately supporting the subject.The control unit 32A then notifies the subject by displaying a message such as "The setting of the medical bed mat is insufficient overall from the shoulders to the legs" on the display unit 32B or by outputting it as voice.

[0054] 6, if there is a large variation in the detected markings 22 (for example, there is a large variation in the longitudinal length of the markings 22 at each position), the control unit 32A determines that there is a portion that is not covered by the medical bed mat 10, and that there is a portion where the subject 16 is not being sufficiently supported by the medical bed mat 10. Then, a message such as "The setting of the medical bed mat is insufficient in the upper arms and legs" is displayed on the display unit 32B or output as voice to notify the user.

[0055] Next, specific processing performed in the medical image inspection system 30 according to this embodiment configured as described above will be described. Fig. 7 is a flowchart showing an example of the flow of processing performed by the control unit 32A of the medical image inspection device or console 34 of the medical image inspection system 30 according to this embodiment. The processing in Fig. 7 starts, for example, when an operator commands the start of the processing, when an operation to move the bed 12 is performed, or when it is detected from the captured image that the technician is no longer present. Furthermore, although the processing will be described below as being performed by the control unit 32A of the medical image inspection device 32, it may also be performed by the control unit 34A of the console 34.

[0056] In step 100, the CPU 32F detects the marking 22 and proceeds to step 102. That is, the CPU 32F obtains the detection result of the detection unit 32D.

[0057] In step 102, the CPU 32F analyzes the detection result of the markings 22, and proceeds to step 104. For example, the CPU 32F determines the state of the detected markings (for example, the number and size of the markings).

[0058] In step 104, the CPU 32F determines whether the setting of the medical bed mat 10 is appropriate. This determination is made by the above-described method for determining whether the medical bed mat 10 is set so as to appropriately support the subject 16. If the determination is negative, the process proceeds to step 106, and if the determination is affirmative, the process proceeds to step 108.

[0059] In step 106, the CPU 32F notifies that the setting of the medical bed mat 10 is insufficient, and ends the series of processes. That is, the CPU 32F notifies that the holding state of the subject 16 by the holding unit 18 is insufficient by displaying a message on the display unit 32B or the like. For example, the CPU 32F notifies that the setting is insufficient by using at least one of sound, light, and display. Note that the CPU 32F may notify the position of the marking 22 that is determined to be insufficient based on the detection result of the marking 22 by the detection unit 32D as the defective part.

[0060] On the other hand, in step 108, the CPU 32F notifies that the setting of the medical bed mat 10 is appropriate, and ends the series of processes. That is, the CPU 32F notifies that the subject 16 is being held properly by the holder 18 by displaying a message on the display unit 32B or the like. For example, the CPU 32F notifies that the setting is appropriate by using at least one of sound, light, and display.

[0061] As described above, in the medical bed mat 10 according to this embodiment, the markings 22 are provided on the holding parts 18, so it is possible to check whether the subject 16 is properly fixed.

[0062] Furthermore, in the medical image inspection system 30 according to this embodiment, it is possible to check whether the subject 16 is properly set on the medical bed mat 10 before capturing a medical image.

[0063] In the above embodiment, the processing in FIG. 7 is described as being performed by the control unit 32A or the control unit 34A, but the processing may be performed by the control unit 32A and the control unit 34A in cooperation with each other, or may be performed in cooperation with another device.

[0064] Furthermore, the various processes performed by the CPU executing software (programs) in the above embodiments may be executed by a computer equipped with various processors other than a CPU. Examples of such processors include programmable logic devices (PLDs) whose circuit configuration can be changed after fabrication, such as field-programmable gate arrays (FPGAs), and dedicated electrical circuits, such as application-specific integrated circuits (ASICs), which are processors with circuit configurations specifically designed to execute specific processes. The various processes may be executed by one of these processors, or by a combination of two or more processors of the same or different types (e.g., multiple FPGAs, or a combination of a CPU and an FPGA). The hardware structure of these processors is, more specifically, an electrical circuit that combines circuit elements such as semiconductor devices.

[0065] In the above embodiment, the various programs are pre-stored (installed) in the ROM 20B, but the present invention is not limited to this. The various programs may be provided in a form recorded on a recording medium such as a CD-ROM (Compact Disk Read Only Memory), a DVD-ROM (Digital Versatile Disk Read Only Memory), or a USB (Universal Serial Bus) memory. The various programs may also be downloaded from an external information processing device or the like via a network.

[0066] Furthermore, the configuration, operation, etc. of the medical image inspection system 30 described in the above embodiment are merely examples, and it goes without saying that they can be modified according to the circumstances within the scope of the present disclosure.
