[0002] An ultrasonic device emits ultrasonic waves to biological tissues, receives the ultrasonic echoes returned by the biological tissues, and then generates ultrasonic images based on the ultrasonic echoes. This examination method is relatively safe for patients and is simple and easy to perform. With the improvement of ultrasonic examination technology and the increase of examination items, the application of ultrasonic devices is becoming more and more extensive.

[0058] The present application will be further described in detail below in conjunction with the accompanying drawings through specific implementation manners. Similar elements in different implementation manners are labeled with related similar element numbers. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification to avoid the core part of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0059] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean that they are the necessary sequences, unless it is stated that a certain sequence must be followed.

[0060] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The terms "connection" and "coupling" used in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0061] For general computer devices (such as desktop phones or laptops, etc.), their input keyboards are generally of a general style, that is, they are laid out with 26 letter keys, supplemented by arrow keys, numeric keys, and other function keys, etc. This is a design solution formed after fully considering the input usage scenarios of general computer devices; similarly, for ultrasonic devices, their usage scenarios generally involve an operator (such as an ultrasonic physician) controlling with one hand through an ultrasonic control panel, and holding an ultrasonic probe with the other hand to perform ultrasonic imaging on the relevant parts of the person being examined. They do not require a large amount of text input like general computer devices; for ultrasonic devices, their control panels need to enable the operator to conveniently and quickly control ultrasonic imaging, including adjusting important and commonly used imaging parameters, and controlling the execution of important and commonly used imaging functions (such as freezing images, thawing images, etc.). Therefore, in theory, although it is also possible to complete the above-mentioned many operations through a common general computer keyboard and the menu system of the display interface, in actual situations, such a design solution will not be adopted because it will greatly reduce the operation efficiency of the physician and bring great inconvenience to the physician.

[0062] Please refer to Figure 1 , a control panel of an ultrasonic device, whose design solution is: it is laid out centered on the frequently used trackball, and common function keys are set around the trackball; in addition, the gain compensation curve (TGC) often needs to be adjusted. When adjusting, it is necessary to adjust multiple depths of the TGC curve respectively. Therefore, in order to save the operation of the physician, TGC sliders corresponding to multiple depths are fixedly set (see the upper right area of the control panel shown in Figure 1 ) for the physician to operate; in addition, in some cases, the physician also needs to input information such as that of the patient. Therefore, an area is also provided on the control panel to set 26 letter keys for the user to input text.

[0063] The applicant analyzed the existing ultrasonic control panel and believed that: multiple TGC sliders increase the thickness of the control panel and greatly reduce the dust and water resistance of the control panel; similarly, the trackball and the surrounding knobs also increase the thickness of the control panel and reduce the dust and water resistance of the control panel; while the button-type function keys can better achieve a relatively thin and light design and are conducive to adding relevant structural designs for dust and water resistance. Therefore, the applicant proposed to improve the relevant function keys in the control panel that affect the thin and light design and increase the difficulty of protection design, so as to improve the thin and light, portable characteristics of the control panel and be conducive to the design of waterproof and dustproof.

[0064] Please refer to Figure 2, some embodiments provide a control panel 100 which is applied to an ultrasonic device; the control panel 100 is for an operator to operate to control the ultrasonic device. In some examples, the control panel 100 has opposite near side 01 and far side 02. The near side 01 is the side of the control panel closer to the operator when being operated by the operator, and the far side 02 is the side of the control panel 100 farther from the operator when being operated by the operator.

[0065] In some embodiments, the control panel 100 has one or more of a first operation area 101, a second operation area 102, and a third operation area 103. Figure 2 Shown is an example where the control panel 100 has a first operation area 101, a second operation area 102, and a third operation area 103.

[0066] The following describes the first operation area 101.

[0067] In some embodiments, a plurality of time gain compensation components 10 associated with a time gain compensation curve are arranged in the first operation area 101. The time gain compensation curve is used to characterize the relationship between depth and gain, and each time gain compensation component 10 corresponds to a depth of the time gain compensation curve.

[0068] First, a description is given to the time gain compensation curve.

[0069] Since ultrasonic waves cause energy losses such as emission and absorption when propagating in human tissues, the intensity of ultrasonic waves radiated into the body decreases with the increase of depth. Similarly, the intensity of the ultrasonic echo signal also attenuates according to the distance traveled. To compensate for this attenuation, different gains are applied to the ultrasonic echo signals collected from different parts of the detection object, such as time gain compensation (TGC, Time Gain Compensation).

[0070] The relationship between different imaging depths and gains is described by the time gain compensation curve. By adjusting the time gain compensation curve, the gains of ultrasonic echo signals at different depths can be set or adjusted, so that the echo signals of the entire ultrasonic field tend to be uniform.

[0071] As described above, each time gain compensation component 10 corresponds to a depth of the time gain compensation curve, and each time gain compensation component 10 can have 6, 7, 8, 9, or 10, etc.; the depths corresponding to these time gain compensation components 10 can be equally spaced. Figure 2 Shown is an example where 8 time gain compensation components 10 are arranged in the first operation area 101 of the control panel 100.

[0072] Figure 3It is a schematic diagram of a display interface A of an ultrasonic device; an ultrasonic image and a TGC curve are displayed in the display interface A, where there are 8 depths from shallow to deep on the TGC curve, namely D1 to D8 in the figure; each depth corresponds to Figure 2 one of the time gain compensation components 10 in Figure 2 Taking it as an example, a time gain compensation component 10 closest to the far side 02 corresponds to the depth D1, and a time gain compensation component 10 farthest from the far side 02 corresponds to the depth D8. These 8 time gain compensation components 10 arranged in the direction from the far side 02 to the near side 01 correspond to the depths D1 to D8 in sequence; for the convenience of subsequent description, these 8 time gain compensation components 10 distributed in the direction from the far side 02 to the near side 01 are named the 1st time gain compensation component 10 to the 8th time gain compensation component 10 in sequence.

[0073] Please refer to Figure 4 In some embodiments, the time gain compensation component 10 includes a first touch area 11 for the operator to perform touch operations; in some examples, the first touch area 11 is rectangular. In some examples, the first touch area 11 includes a plurality of first sub-touch areas 12 distributed along its long axis direction. Each first sub-touch area 12 corresponds to a gain. When any first sub-touch area 12 is touched by the operator, a time gain setting signal can be generated, and the time gain setting signal is used to set the gain corresponding to the depth of the time gain compensation component 10 where the first sub-touch area 12 is located on the time gain compensation curve to the gain corresponding to the first sub-touch area 12.

[0074] Figure 4 What is shown is a schematic diagram in which the first touch area 11 has 11 first sub-touch areas 12. Each first sub-touch area 12 corresponds to a gain. For example, for these 11 first sub-touch areas 12, from left to right in the figure, the corresponding gains increase in sequence and are G1 to G11 respectively; for the convenience of subsequent description, these 11 first sub-touch areas 12 distributed from left to right are named the 1st first sub-touch area 12 to the 11th first sub-touch area 12 in sequence. Therefore, when the 5th first sub-touch area 12 of the 2nd time gain compensation component 10 is touched, the corresponding gain at the D2 depth of the TGC curve is set to G5.

[0075] For the convenience of the operator's understanding and operation, in some embodiments, each first touch area 11 is arranged in the first operation area 101 in a direction parallel to the long axis direction thereof, and each first touch area 11 is arranged in sequence in a direction perpendicular to the long axis direction according to the size order of the corresponding depths of the respective time gain compensation components 10. In some embodiments, the long axis direction of the first touch area 11 is also parallel to the near side edge 01 or the far side edge 02 of the control panel 100, and the first touch area 11 with the smallest corresponding depth of the time gain compensation component 10 where it is located is arranged closest to the far side edge 02 of the control panel 100.

[0076] Please refer to Figure 5 , in some embodiments, the first sub-touch area 12 has a first electrode 12a, a second electrode 12b, and a sensing member 12c; the sensing member 12c is arranged on the surface of the first sub-touch area 12 for sensing the touch operation of the operator. The sensing member 12c receives a first detection signal from the first electrode 12a and outputs a first trigger signal through the second electrode 12b when sensing the touch operation of the operator, serving as a time gain setting signal. In some examples, the sensing member 12c can be a capacitor device.

[0077] Figure 5 A schematic diagram of the circuit connection of the sensing members 12c in the same time gain compensation component 10 shown. The first electrodes 12a of the sensing members 12c in the same time gain compensation component 10 can be connected together and receive the first detection signal, and the second electrodes 12b of the sensing members 12c in the same time gain compensation component 10 are independently output. When any one of the sensing members 12c is touched, a first trigger signal is output through its second electrode 12b.

[0078] Please refer to Figure 6 , in order to remind the operator of the currently set gain value, in some embodiments, the time gain compensation component 10 further includes a first light-emitting component 13 arranged below the first touch area 11. The first light-emitting component 13 includes a plurality of first light-emitting devices 14. The plurality of first light-emitting devices 14 are distributed along the long axis direction of the first touch area 11 such that each first sub-touch area 12 corresponds to at least one first light-emitting device 14. When any one of the first sub-touch areas 12 is touched by the operator, the corresponding first light-emitting device 14 will be turned on to emit light; wherein, the first sub-touch area 12 includes a light-transmitting area that can allow the light when the first light-emitting device 14 corresponding to the first sub-touch area 12 emits light to pass through; for example, the first sub-touch area 12 is made of a light-transmitting or semi-light-transmitting material, so that the entire first sub-touch area 12 is a light-transmitting area. In some examples, the first light-emitting device 14 is an LED. It should be noted that Figure 6 The black-slash-filled circle in

[0079] In some embodiments, the first light-emitting component 13 further includes a first driving signal generation circuit 15. The first driving signal generation circuit 15 is configured to generate a driving signal based on a first trigger signal output by the first sub-touch area 12 through its second electrode 12b and output the driving signal to the first light-emitting device 14 corresponding to the first sub-touch area 12 to drive the first light-emitting device 14 to emit light.

[0080] Therefore, the first trigger signal output by the first sub-touch area 12 through its second electrode 12b has two functions. One is as a time gain setting signal, and the other is to trigger the first driving signal generation circuit 15 to generate a driving signal to drive the first light-emitting device 14 to emit light.

[0081] By introducing the first light-emitting component 13, the operator can know the gain value situation corresponding to the corresponding depth by viewing the currently lit first sub-touch area 12 on the time gain compensation component 10, which is very convenient.

[0082] To facilitate the operator to quickly restore or set the gain at each depth, the first operation area 101 is also provided with a quick setting key 15. When the quick setting key 15 is triggered, a quick gain setting signal can be generated. The quick gain setting signal is used to set the gain at each depth on the time gain compensation curve to a preset gain value. In some examples, the preset gain value is the minimum gain value, the maximum gain value or the intermediate gain value. It can be understood that both the minimum gain value and the maximum gain value can be preset values, which respectively correspond to the minimum gain and the maximum gain that the time gain compensation component 10 can set; and the intermediate gain value corresponds to the gain value corresponding to the middle first sub-touch area 12 of the time gain compensation component 10.

[0083] In some examples, when the quick setting key 15 is triggered to generate a quick gain setting signal to set the gain at each depth on the time gain compensation curve, to prompt the operator, the first light-emitting device 14 of the first sub-touch area 12 corresponding to the preset gain value is also lit in the first light-emitting component 13. One implementation manner may be that after receiving the above quick gain setting signal, the first driving signal generation circuit 15 generates a driving signal and outputs it to the first light-emitting device 14 of the first sub-touch area 12 corresponding to the preset gain value to drive the corresponding first light-emitting device 14 to emit light.

[0084] In some embodiments, the quick setting key 15 is a physical function key; in some examples, such a physical function key is a physical key in the form of a button, that is, the quick setting key 15 is a physical key in the form of a button; compared with function keys with structures such as a joystick and a direction key, the quick setting key 15 being a physical key in the form of a button is beneficial to thin and light design and waterproof and dustproof design.

[0085] In order to prevent misoperation, in some examples, the quick setting key 15 needs to be continuously pressed twice to generate the above-mentioned quick gain setting signal.

[0086] In some embodiments, the quick setting key 15 is a touch-type key. The quick setting key 15 includes a second touch area for the operator to perform a touch operation, which is used for the operator to perform a touch operation.

[0087] In order to prevent misoperation, in some examples, the second touch area of the quick setting key 15 needs to be continuously touched twice to generate the above-mentioned quick gain setting signal.

[0088] In order to prevent misoperation, in some examples, the quick setting key 15 is set at a first position in the first operation area 101, so that the distance between the quick setting key 15 and the first touch area 11 of the nearest time gain compensation component 10 is greater than the first distance.

[0089] The above are some descriptions of the first operation area 101.

[0090] In some embodiments, the second operation area 102 is provided with one or both of a touch encoder component 20 and a touchpad component 30.

[0091] Please refer to Figure 7 , in some embodiments, the touch encoder component 20 includes a second touch area 21 for the operator to perform a touch operation. The second touch area 21 includes a plurality of second sub-touch areas 22, and each second sub-touch area 22 corresponds to an encoder adjustment value; when any one of the second sub-touch areas 22 is touched by the operator, a parameter adjustment signal can be generated, and the parameter adjustment signal is used to set the parameter to be adjusted to the encoder adjustment value corresponding to the second sub-touch area 22. Figure 7 The medium gray filled circles are used to represent the second sub-touch areas 22.

[0092] In some embodiments, the touch encoder component 20 is used to replace a physical encoder knob. Therefore, in order not to change the operator's operation habits and familiarity with the layout of the function keys, the second touch area 21 of the touch encoder component 20 can be circular, and the plurality of second sub-touch areas 22 are distributed in an arc shape within the second touch area 21.

[0093] In some examples, the second sub-touch areas 22 in the same touch encoder component 20 are distributed in an arc shape within the second touch area 21 in a clockwise direction from small to large according to their corresponding encoder adjustment values.

[0094] Please refer to Figure 8, To remind the operator of the encoder adjustment value of the current touch encoder component 20, in some embodiments, the touch encoder component 20 further includes a second light-emitting component 23 disposed below the second touch area 21. The second light-emitting component 23 includes a plurality of second light-emitting devices 24, and each second sub-touch area 22 corresponds to at least one second light-emitting device 24. When any second sub-touch area 22 is touched by the operator, the corresponding second light-emitting device 24 will be turned on to emit light; wherein, the second sub-touch area 22 corresponds to a light-transmitting area 26 on the second touch area 21 —— Figure 9 As an example, the light-transmitting area 26 can allow the light when the second light-emitting device 24 corresponding to the second sub-touch area 22 emits light to pass through. In some examples, the second light-emitting device 24 is an LED. Figure 8 The medium-gray filled circle is used to represent the second sub-touch area 22, and the black-slash filled circle is used to represent the second light-emitting device 24.

[0095] In some embodiments, the second light-emitting component 22 further includes a second drive signal generation circuit 25. The second drive signal generation circuit 25 is used to generate a drive signal according to the parameter adjustment signal that can be generated when the second sub-touch area 22 is touched by the operator and output it to the second light-emitting device 24 corresponding to the second sub-touch area 22 to drive the corresponding second light-emitting device 24 to emit light.

[0096] Therefore, when the second sub-touch area 22 is touched by the operator, it can generate a parameter adjustment signal, which has two functions. One is to adjust the encoder value, and the other is to trigger the second drive signal generation circuit 25 to generate a drive signal to drive the second light-emitting device 24 to emit light.

[0097] In some examples described above, the second sub-touch areas 22 in the same touch encoder component 20 are distributed in an arc shape in the second touch area 21 in a clockwise direction from small to large according to their corresponding encoder adjustment values; the light-transmitting areas 26 corresponding to each second sub-touch area 22 are all circular and have different sizes. The larger the area of the light-transmitting area 26 corresponding to the encoder adjustment value corresponding to the second sub-touch area 22.

[0098] By introducing the second light-emitting component 22, the operator can know the setting situation of the corresponding parameters by viewing the currently lit second sub-touch area 22 on the touch encoder component 20, which is very convenient.

[0099] Please refer to Figure 10 , In some embodiments, the touchpad component 30 includes a third touch area 31 for the operator to perform a touch operation. The third touch area 31 includes a plurality of third sub-touch areas 32 arranged in a two-dimensional manner. When any third sub-touch area 32 is touched by the operator, it can generate a third trigger signal, and the third trigger signal is used to determine the coordinate information currently touched by the operator. Figure 10The large circle in the middle represents the third touch area 31, and the small areas divided by horizontal and vertical lines within the large circle represent the third sub-touch areas 32.

[0100] In some embodiments, the touchpad assembly 30 is used to replace the physical trackball. Therefore, in order not to change the operator's operating habits and familiarity with the layout of the function keys, the third touch area 31 of the touchpad assembly 30 can be circular.

[0101] In some embodiments, other function keys can also be provided within the second operation area 102. The forms of these function keys are preferably physical keys in the form of buttons, such as the B mode key, C mode key, M mode key, image freeze key, image thaw key, etc. Figure 2 In the shown control panel 100, the keys filled with gray in the second operation area 102 are some common function keys, and their forms are preferably physical keys in the form of buttons.

[0102] In some embodiments, 26 letter keys can be provided within the third operation area 103, as well as some common function keys of a general computer keyboard such as the enter key and space bar. The forms of these keys provided in the third operation area 103 are preferably physical keys in the form of buttons.

[0103] Please refer to Figure 11 , in some embodiments, the control panel 100 includes a silicone outer cover 110, a control circuit board 120, and a base 130. The silicone outer cover 110 and the control circuit board 120 are fixed to each other, and the silicone outer cover 110 and the control circuit board 120 are also fixed to the base 130; one or more of the time gain compensation component 10, quick setting key 15, touch encoder component 20, and touchpad component 30 mentioned above are provided on the control circuit board 120. In addition, other function keys mentioned above are also provided on the control circuit board 120; the silicone outer cover 110 includes a manipulation part 111 corresponding to the physical key in the form of a button on the control circuit board 120, and a non-covering area 112 for exposing the corresponding touch areas (such as the first touch area 11, the second touch area 21, and the third touch area 31); the periphery of the non-covering area 112 in contact with the corresponding touch areas (such as the first touch area 11, the second touch area 21, and the third touch area 31) is tightly fitted and sealed to prevent dust and / or water. In one case, the silicone outer cover can also be made to cover all touch areas.
