[0043] To make the objectives, technical solutions and advantages of the present application more clear and understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] The scanning method provided by the present application can be applied to a computer device. The computer device can be a server or a terminal.

The input device of the computer device can be a touch layer covered on the display screen, or a button, a trackball or a touchpad provided on the housing of the computer device, or an external keyboard, a touchpad or a mouse, etc.

[0046] Those skilled in the art can understand that Figure 1 the structure shown in

[0047] is only a block diagram of a part of the structure related to the solution of the present application, and does not constitute a limitation on the terminal to which the solution of the present application is applied. Optionally, the terminal may include more or fewer components than those shown in the figure, or combine some components, or have a different component layout.

[0048] In one embodiment, as Figure 2 shown, it shows a flowchart of a control method for a medical scanning device provided by an embodiment of the present application. The method may include the following steps:

[0049] Step 220: Obtain a fixed trigger signal.

[0050] The fixed trigger signal is a signal used to trigger the fixation of the object to be scanned on the scanning bed. When scanning the object to be scanned, after the object to be scanned lies on the scanning bed, it is necessary to fix the object to be scanned on the scanning bed to prevent artifacts in the scanned image caused by the object moving randomly during the scanning process, resulting in a decrease in the quality of the scanned image and affecting the subsequent analysis of the scanned image, especially for objects to be scanned with low cooperation such as children, animals, and unconscious objects to be scanned.

[0051] The fixed trigger signal can be a signal manually triggered by an operator; it can also be a signal automatically generated based on relevant information of the object to be scanned. For example, a fixed trigger signal is automatically generated when it is detected that the object to be scanned has not been positioned for a long time, or a fixed trigger signal is automatically generated when it is detected that the physiological information of the object to be scanned meets the requirements; of course, it can also be a signal generated based on other methods, and this embodiment does not make specific limitations on this.

[0052] Step 240: In response to the fixed trigger signal, adjust some or all areas of the scanning bed to fix the object to be scanned on the scanning bed.

[0053] Among them, when fixing the object to be scanned on the scanning bed, the fixation operation on the scanning bed is triggered based on the obtained fixed trigger signal. Optionally, since at least some areas of the scanning bed can rise or fall, based on the fixed trigger signal, some or all areas of the scanning bed can be controlled to rise or fall, thereby fixing the object to be scanned on the scanning bed.

[0054] Step 260: Obtain a first trigger signal and send the first trigger signal to the medical scanning device. The first trigger signal is used to instruct the medical scanning device to scan the object to be scanned.

[0055] Among them, in the case where the object to be scanned is fixed on the scanning bed, a first trigger signal can be generated. The first trigger signal is used to instruct the medical scanning device to scan the object to be scanned. The first trigger signal can be a signal manually triggered by an operator after determining that the object to be scanned is successfully fixed on the scanning bed; it can also be a signal automatically generated by the scanning bed after automatically determining that the object to be scanned is successfully fixed on the scanning bed.

[0056] After generating the first trigger signal, the computer device that generates the first trigger signal communicates with the medical scanning device, so that the first trigger signal can be sent to the medical scanning device; moreover, the medical scanning device is coupled to the scanning bed and can move the scanning bed carrying the object to be scanned into the medical scanning device, so that the medical scanning device scans the object to be scanned based on the first trigger signal. The medical scanning device may include, but is not limited to, medical imaging devices such as CT devices, ultrasound devices, and nuclear magnetic resonance devices.

[0057] In this embodiment, a fixed trigger signal is obtained; in response to the fixed trigger signal, a partial area or the entire area of the scanning bed is adjusted to fix the object to be scanned on the scanning bed; the first trigger signal is obtained and sent to the medical scanning device, and the first trigger signal is used to instruct the medical scanning device to scan the object to be scanned. Since the object to be scanned can be fixed on the scanning bed to prevent the object to be scanned from moving randomly during the scanning process, artifacts in the scanned image are avoided, the quality of the scanned image is improved, and the accuracy of the scanning result is further improved.

[0058] In one embodiment, as Figure 3 shown, it shows a flowchart of a control method for a medical scanning device provided by an embodiment of the present application, specifically related to a possible process of obtaining a fixed trigger signal. The method may include the following steps:

[0059] Step 320, obtain the current pose information of the object to be scanned.

[0060] Among them, the current pose information of the object to be scanned may include the position information, shape information, etc. of the object to be scanned on the scanning bed, and the current pose information of the object to be scanned can be obtained by analyzing and recognizing the image of the object to be scanned collected by an image acquisition device arranged outside the scanning bed. Optionally, the coordinate information of the object to be scanned can be extracted from the collected image of the object to be scanned, so as to determine the current pose information of the object to be scanned; alternatively, a preset neural network model can be used to process the image of the object to be scanned, so as to output the current pose information of the object to be scanned corresponding to the image of the object to be scanned. The preset neural network model can be pre-trained according to the historical image information and the corresponding pose information of the object to be scanned; of course, other methods can also be used to process the image of the object to be scanned to obtain the current pose information of the object to be scanned, and this embodiment does not make specific limitations on this; of course, it can also be obtained by a pose acquisition device arranged on the scanning bed, such as a gravity sensor and other pose acquisition devices. Optionally, multiple gravity sensors can be arranged on the scanning bed, so as to determine the current pose information of the object to be scanned according to the position information of the gravity sensors that can collect gravity values.

[0061] Step 340: If the current pose information of the object to be scanned conforms to the preset pose information, send a fixed trigger signal.

[0062] Among them, it is possible to compare the current pose information of the object to be scanned with the preset pose information. If the current pose information of the object to be scanned conforms to the preset pose information, a fixed trigger signal is sent. Optionally, it is possible to calculate the similarity between the image of the object to be scanned and the reference image, and judge whether the current pose information of the object to be scanned conforms to the preset pose information according to the value of the similarity. Here, the reference image includes the preset pose information.

[0063] Optionally, if the current pose information of the object to be scanned does not conform to the preset pose information, pose adjustment information can also be generated. The pose adjustment information is used to instruct the object to be scanned to adjust its pose. The pose adjustment information can be output in at least one of the ways of text, animation, voice, etc. Of course, other forms can also be used for output. This embodiment does not make specific limitations on this.

[0064] In this embodiment, by obtaining the current pose information of the object to be scanned; if the current pose information of the object to be scanned conforms to the preset pose information, a fixed trigger signal is sent. This method is simple and easy to implement, and improves the efficiency and accuracy of generating the fixed trigger signal.

[0065] In one embodiment, as Figure 4 shown, it shows a flowchart of a control method for a medical scanning device provided by an embodiment of the present application. Specifically, it relates to a possible process of obtaining the current pose information of the object to be scanned. The method may include the following steps:

[0066] Step 420: Collect the current physiological information of the object to be scanned through the scanning bed. If the current physiological information of the object to be scanned conforms to the preset physiological information conditions, generate a second trigger signal.

[0067] Among them, when scanning the object to be scanned, it is usually necessary to monitor the current physiological information of the object to be scanned. For example, it is necessary to monitor the heart rate information of the object to be scanned. When collecting the current physiological information of the object to be scanned through the scanning bed, in the traditional method, it is usually necessary to externally connect a third-party device to monitor the physiological information. Specifically, a device for externally monitoring the heart rate can be bound to the body of the object to be scanned. However, this method is prone to problems such as poor contact. Moreover, when scanning the cardiac protocol, it is necessary to perform operations related to scanning and reconstruction according to the monitored cardiac waveform. Abnormal device signals will affect the scanning and reconstruction of the cardiac protocol.

[0068] In this embodiment, the current physiological information of the object to be scanned can be collected by sensors arranged on the scanning bed, and the sensors can be arranged inside or on the surface of the scanning bed. Specifically, a plurality of sensors are arranged in the area corresponding to the physiological information to be collected. For example, acoustic sensors can be arranged in the heart area to collect the current heart rate information of the object to be scanned.

[0069] After obtaining the current physiological information of the object to be scanned, the current physiological information can be compared with the preset physiological information conditions. If the current physiological information of the object to be scanned meets the preset physiological information conditions, a second trigger signal is generated. For example, after collecting the current heart rate information of the object to be scanned, the current heart rate information can be compared with the preset heart rate information conditions to determine whether the current heart rate information is consistent with the preset heart rate information conditions or within a certain range, so as to determine whether the current heart rate information of the object to be scanned meets the preset heart rate information conditions.

[0070] Step 440: Obtain the current pose information of the object to be scanned based on the second trigger signal.

[0071] Among them, after the second trigger signal is generated, the image acquisition device or other pose acquisition device for collecting the current pose information of the object to be scanned can be controlled based on the second trigger signal to work, so as to obtain the current pose information of the object to be scanned.

[0072] In this embodiment, the current physiological information of the object to be scanned is collected by the scanning bed. If the current physiological information of the object to be scanned meets the preset physiological information conditions, a second trigger signal is generated; the current pose information of the object to be scanned is obtained based on the second trigger signal. Since the current physiological information of the object to be scanned can be directly collected by the scanning bed without connecting external third-party devices, it not only saves space, but also can more accurately obtain the current physiological information of the object to be scanned, and improves the reliability of obtaining the current physiological information.

[0073] In one embodiment, as Figure 5 shown, it shows a flowchart of a control method for a medical scanning device provided by an embodiment of the present application, specifically related to a possible process of obtaining the current physiological information of the object to be scanned. The method may include the following steps:

[0074] Step 520: Extract the identifier of the part to be scanned of the object to be scanned, and determine the target position of the part to be scanned of the object to be scanned based on the identifier of the part to be scanned.

[0075] Among them, the identifier of the part to be scanned is used to uniquely mark the part to be scanned. A corresponding relationship between the part to be scanned and the identifier can be established in advance. The specific type of the identifier is not limited in this embodiment. After the identifier of the part to be scanned is extracted, the target position of the part to be scanned of the object to be scanned can be determined based on the identifier of the part to be scanned. For example, if the identifier of the part to be scanned is a heart identifier, then the target position of the part to be scanned determined based on the heart identifier is the heart area.

[0076] Step 540: Determine the second sensor at the target position.

[0077] Among them, since corresponding sensors can be set in multiple areas on the scanning bed, but in actual applications, not all sensors work simultaneously. Therefore, the second sensor at the target position can be determined based on the target position of the part to be scanned of the object to be scanned that is determined. For example, if the identifier of the part to be scanned is a heart identifier, and the target position of the part to be scanned determined based on the heart identifier is the heart area, then the second sensor at the heart area needs to be determined.

[0078] Step 560: Control the second sensor to collect the current physiological information of the part to be scanned of the object to be scanned based on the control instruction.

[0079] Among them, the control instruction can be manually triggered by the operator; it can also be automatically generated after detecting that the object to be scanned lies on the scanning bed. The second sensor at the target position can collect the current physiological information of the part to be scanned of the object to be scanned based on this control instruction.

[0080] In this embodiment, by extracting the identifier of the part to be scanned of the object to be scanned, and determining the target position of the part to be scanned of the object to be scanned based on the identifier of the part to be scanned; determining the second sensor at the target position; controlling the second sensor to collect the current physiological information of the part to be scanned of the object to be scanned based on the control instruction. Since the corresponding data can be collected by controlling different sensors according to the positions of different parts to be scanned, the flexibility and intelligence of collecting physiological information are improved.

[0081] Based on the above embodiment, as Figure 6 shown, it shows a flowchart of a control method of a medical scanning device provided by an embodiment of the present application, specifically relating to a possible process of judging the current physiological information. The method may include the following steps:

[0082] Step 620: Judge whether the current physiological information of the object to be scanned collected by the scanning bed meets the preset physiological information condition.

[0083] Step 640: If the current physiological information of the object to be scanned does not meet the preset physiological information condition, generate a physiological information adjustment instruction based on the current physiological information of the object to be scanned.

[0084] Among them, after comparing the current physiological information of the object to be scanned with the preset physiological information condition, if the current physiological information of the object to be scanned does not meet the preset physiological information condition, a physiological information adjustment instruction can also be generated based on the current physiological information of the object to be scanned. This physiological information adjustment instruction is used to instruct the object to be scanned to perform physiological training. For example, in the case where it is monitored that the heart rate information of the object to be scanned does not meet the preset heart rate information condition, a heart rate information adjustment instruction can be output to instruct the object to be scanned to re-perform heart rate training. The physiological information adjustment instruction can be output in at least one of the ways of text, animation, voice, etc. Of course, it can also be output in other forms, and this embodiment does not make specific limitations on this.

[0085] In this embodiment, by judging whether the current physiological information of the object to be scanned collected by the scanning bed meets the preset physiological information condition; if the current physiological information of the object to be scanned does not meet the preset physiological information condition, a physiological information adjustment instruction is generated based on the current physiological information of the object to be scanned, which improves the efficiency of physiological training.

[0086] In one embodiment, adjusting some areas or all areas of the scanning bed to fix the object to be scanned on the scanning bed includes: controlling the lifting of a plurality of lifting devices on the scanning bed. When the plurality of lifting devices are lifted to the first target position, the plurality of lifting devices are used to fix the object to be scanned on the scanning bed; the plurality of lifting devices are arranged at positions corresponding to the scanning bed area; and / or, controlling the plurality of moving devices on the scanning bed to move in the horizontal direction to fix the object to be scanned on the scanning bed in the horizontal direction.

[0087] Among them, the lifting devices are all arranged on the scanning bed, and the lifting devices can be cylindrical, cubic, etc. Of course, they can also be of other shapes, and this embodiment does not make specific limitations on this.

[0088] Optionally, the plurality of lifting devices include a plurality of first lifting columns; the first lifting columns are used to hold the object to be scanned in the horizontal direction; controlling the lifting of the plurality of lifting devices on the scanning bed. When the plurality of lifting devices are lifted to the first target position, the plurality of lifting devices are used to fix the object to be scanned on the scanning bed, including: controlling the plurality of first lifting columns to be lifted to the first target position at the contour of the object to be scanned.

[0089] Among them, such as Figure 7As shown in the figure, a plurality of first lifting columns are arranged on the scanning bed. When each first lifting column is controlled to lift to a first target position, the plurality of first lifting columns are used to fix the object to be scanned on the scanning bed. The plurality of lifting columns are arranged at positions corresponding to the scanning bed area and can be evenly arranged on the scanning bed in sequence to form a lifting column array.

[0090] Specifically, the first target position is a position that extends beyond the target surface of the object to be scanned in the horizontal direction, and the target surface is the side of the object to be scanned away from the scanning bed. The first lifting column can be a lifting column located at the body contour of the object to be scanned. Thus, by controlling the motor to drive each first lifting column to lift to a position that extends beyond the target surface of the object to be scanned in the horizontal direction, the object to be scanned can be clamped on the scanning bed, so as to fix the object to be scanned.

[0091] The above-mentioned plurality of moving devices are modules that can move horizontally. Each moving device can be respectively arranged on the lifting module 301 or can be arranged independently. This embodiment does not make specific limitations on this. Optionally, the moving device can move horizontally according to the contour area of the object to be scanned. In the initial state, the moving device can form a large "human" shape, so as to wrap the object to be scanned. After the object to be scanned lies down, the motor can be controlled to drive each moving device to move horizontally towards the contour of the object to be scanned, so that each moving device fits the object to be scanned in the horizontal direction, thereby fixing the object to be scanned in the horizontal direction. Each moving device can also adopt a sponge material, so as to increase the comfort of the object to be scanned while fixing it.

[0092] In this embodiment, by controlling the plurality of first lifting columns to lift to the first target position at the contour of the object to be scanned, the object to be scanned is fixed on the scanning bed. Since the first lifting column lifts in accordance with the body contour of the object to be scanned, the object to be scanned is clamped on the scanning bed. By adopting this method, the object to be scanned can be fixed more firmly.

[0093] In one embodiment, as Figure 8 shown, it shows a flowchart of a control method for a medical scanning device provided by an embodiment of the present application, specifically relating to a possible process of controlling the first lifting column. The method may include the following steps:

[0094] Step 820: Obtain the pressure value on the first lifting column through the pressure sensor on the first lifting column.

[0095] Among them, the pressure sensor can be built in the first lifting column or can be arranged on the surface of the first lifting column, so that when the object to be scanned is fixed by the first lifting column, the pressure values on each first lifting column can also be obtained.

[0096] Step 840: If the pressure value exceeds the preset pressure threshold, control the first lifting column to lower below the first target position, and control the second lifting column to lift to the first target position at the contour of the object to be scanned.

[0097] Among them, the preset pressure threshold can be pre-customized according to experience. Compare the obtained pressure value on the first lifting column with the preset pressure threshold. If the pressure value exceeds the preset pressure threshold, it means that the object to be scanned is fixed too tightly at this time, causing a large extrusion on the body of the object to be scanned, thereby reducing the comfort of the object to be scanned lying on the scanning bed.

[0098] At this time, the motor can be controlled to drive the first lifting column to lower below the first target position. Since the multiple lifting devices can also include multiple second lifting columns, the motor can be controlled to drive the second lifting columns to lift to the first target position at the contour of the object to be scanned. The second lifting columns are adjacent to the first lifting column and are located outside the first lifting column, that is, the second lifting columns are used to fix the object to be scanned. Of course, there can be multiple second lifting columns located outside one first lifting column, so that the pressure values on each second lifting column can be repeatedly judged until the pressure value on the second lifting column does not exceed the preset pressure threshold, and then the current second lifting column is used to fix the object to be scanned.

[0099] In this embodiment, the pressure value on the first lifting column is obtained through the pressure sensor on the first lifting column; if the pressure value exceeds the preset pressure threshold, control the first lifting column to lower below the first target position, and control the second lifting column to lift to the first target position at the contour of the object to be scanned. This way improves the flexibility when fixing the object to be scanned and also improves the comfort of the object to be scanned lying on the scanning bed.

[0100] In one embodiment, the above multiple lifting devices further include multiple third lifting columns; the third lifting columns are used to support the object to be scanned in the vertical direction; fixing the object to be scanned on the scanning bed further includes: controlling the third lifting columns to lift to the second target position according to the attribute information of the object to be scanned, so that the third lifting columns support the object to be scanned in the vertical direction; the attribute information of the object to be scanned includes at least one of gravity information, current posture information, and contour information.

[0101] Among them, the multiple lifting devices can also include multiple third lifting columns, and the third lifting columns are used to support the object to be scanned in the vertical direction, that is, the third lifting columns are the lifting columns located below the body of the object to be scanned. In order to better support the object to be scanned and thus realize the fixation of the scanned object, the third lifting columns can be controlled to lift to the second target position according to the attribute information of the object to be scanned, so that the third lifting columns support the object to be scanned in the vertical direction.

[0102] Specifically, the attribute information of the object to be scanned may include at least one of gravity information, current posture information, and contour information, and the second target position is a position that fits the body of the object to be scanned. As Figure 9 shown, after the object to be scanned lies on the scanning bed, the third lifting columns can first be lifted and lowered to a unified height to support the object to be scanned. At this time, since the body of the object to be scanned is not a flat surface and has certain concavities and convexities, some of the third lifting columns will fit the body of the object to be scanned, and the gravity sensors on them can collect the gravity information of the object to be scanned, while the gravity sensors on some of the third lifting columns do not collect the gravity information of the object to be scanned. At this time, the third lifting columns that do not collect the gravity information of the object to be scanned can be adjusted, and the third lifting column can be driven by a motor to rise until the gravity information can be collected. Optionally, corresponding image acquisition devices can also be arranged on the side of the scanning bed, so as to judge whether the third lifting column fits the body of the object to be scanned according to the image information of the third lifting column and the object to be scanned collected by the image acquisition device, and adjust the corresponding third lifting column according to the judgment result.

[0103] Similarly, the third lifting columns at the corresponding positions can be determined according to the current posture information and contour information of the object to be scanned, so as to control the third lifting columns to be lifted and lowered to the second target position. And, since the current posture information and contour information can represent the body shape information of the object to be scanned, the third lifting columns can also be controlled to fit the body shape of the object to be scanned more closely based on the current posture information and contour information.

[0104] In this embodiment, by controlling the third lifting columns to be lifted and lowered to the second target position according to the attribute information of the object to be scanned, so that the third lifting columns support the object to be scanned in the vertical direction, the third lifting columns can fit the body shape of the object to be scanned better, so as to better support the object to be scanned, and further fix the object to be scanned in the vertical direction, and at the same time improve the comfort of the object to be scanned lying on the scanning bed.

[0105] In one embodiment, as Figure 10 shown, it shows a flowchart of a control method for a medical scanning device provided by an embodiment of the present application. The method may include the following steps:

[0106] Step 1001: Extract the identifier of the part to be scanned of the object to be scanned, and determine the target position of the part to be scanned of the object to be scanned based on the identifier of the part to be scanned.

[0107] Step 1002: Determine the second sensor at the target position.

[0108] Step 1003: Control the second sensor to collect the current physiological information of the part to be scanned of the object to be scanned based on the control instruction.

[0109] Step 1004: If the current physiological information of the object to be scanned meets the preset physiological information condition, generate a second trigger signal.

[0110] Step 1005: Obtain the current pose information of the object to be scanned based on the second trigger signal.

[0111] Step 1006: If the current physiological information of the object to be scanned does not meet the preset physiological information condition, generate a physiological information adjustment instruction based on the current physiological information of the object to be scanned.

[0112] Step 1007: Obtain the current pose information of the object to be scanned.

[0113] Step 1008: If the current pose information of the object to be scanned meets the preset pose information, send a fixed trigger signal.

[0114] Step 1009: Control multiple first lifting columns to lift and lower to the first target position at the contour of the object to be scanned. In the case where the multiple lifting devices lift and lower to the first target position, the multiple lifting devices are used to fix the object to be scanned on the scanning bed.

[0115] Step 1010: Obtain the pressure value on the first lifting column through the pressure sensor on the first lifting column.

[0116] Step 1011: If the pressure value exceeds the preset pressure threshold, control the first lifting column to lower below the first target position, and control the second lifting column to lift and lower to the first target position at the contour of the object to be scanned.

[0117] Step 1012: Control the third lifting column to lift and lower to the second target position according to the attribute information of the object to be scanned, so that the third lifting column supports the object to be scanned in the vertical direction.

[0118] In this embodiment, since the object to be scanned can be fixed on the scanning bed to prevent the object to be scanned from moving randomly during the scanning process, artifacts in the scanned image are avoided, the quality of the scanned image is improved, and thus the accuracy of the scanning result is improved.

[0119] Based on the above embodiment, the sensor for collecting the current physiological information of the object to be scanned can also be set on the surface of each lifting column or built into each lifting column. Please continue to refer to Figure 7 , where an acoustic wave sensor can be built into the lifting column in the heart area to monitor the heart rate information of the object to be scanned. Further, please continue to refer to Figure 9, a contrast agent injection device, an interventional device, etc. can also be placed under the bed board of the scanning bed. For example, a high-pressure syringe, and the injection catheter can also be led out through a lifting column to inject drugs into the object to be scanned. This can greatly save space, make the scanning room have a larger and more flexible space, and at the same time avoid situations where too many external third-party devices cause operators to stumble or fall.
