[0041] In this embodiment, a control method for a magnetic resonance system is provided. Figure 2 is a flow chart of the control method of the magnetic resonance system of this embodiment. Figure 2 As shown, the process includes the following steps:

[0042] Step S210, obtaining the three-dimensional body shape features and the part to be scanned of the scanned object.

[0043] Among them, the above-mentioned magnetic resonance system refers to a system for magnetic resonance scanning that integrates a scanning bed, a scanning coil for magnetic resonance, a gradient system, a radio frequency system and a computer system. In addition, the magnetic resonance system can also be equipped with an instrument for three-dimensional scanning, an instrument for height measurement and an instrument for weight measurement on the basis of relevant technologies, so as to obtain more information about the scanned object itself before the magnetic resonance scanning. The scanned object refers to an object that needs to be scanned by magnetic resonance. The three-dimensional body shape feature refers to the feature that describes the three-dimensional outer contour information of the body of the scanned object. The part to be scanned refers to the part of the scanned object that needs to be scanned by magnetic resonance. Further, the three-dimensional body shape feature of the scanned object can be determined by pre-scanning before the magnetic resonance scanning. For example, a three-dimensional scanning device such as a three-dimensional scanner, a depth camera and a laser radar is used to collect the three-dimensional outer contour of the body of the scanned object to obtain the three-dimensional body shape feature of the scanned object. Preferably, a three-dimensional scanning area can be set in the magnetic resonance system. When the scanned object reaches the three-dimensional scanning area, the scanned object is three-dimensionally scanned by a three-dimensional scanner to reconstruct the three-dimensional body shape feature of the scanned object.

[0044] The above-mentioned part to be scanned can be determined based on the three-dimensional body shape features determined by the scanned object and with reference to the distribution positions of various organs of the human body. It should be noted that the distribution positions of various organs of the human body in the human body are fixed. Therefore, after obtaining the three-dimensional body shape features, the distribution positions of various organs of the human body can be matched to determine the part to be scanned of the scanned object, thereby realizing the scanning and positioning of small parts. For example, when it is necessary to scan the hippocampus in the head of the scanned object, after obtaining the three-dimensional body shape features of the scanned object, since the position of the hippocampus in the human head is fixed, the part to be scanned corresponding to the position of the organ can be determined based on the three-dimensional body shape features of the scanned object and the position of the organ in the human body. Based on this, the present embodiment can accurately locate the organs of the scanned object based on the three-dimensional body shape features of the scanned object. In addition, after determining the part to be scanned of the scanned object, the part to be scanned can also be combined with the height information and weight information of the scanned object for subsequent calculation of the specific absorption rate (Specific Absorption Rate, referred to as SAR) model of radio frequency energy.

[0045] Step S220, based on the three-dimensional body shape features and the part to be scanned, controlling the scanning coil of the magnetic resonance system to cover the part to be scanned.

[0046] After obtaining the three-dimensional body shape features and the part to be scanned of the scanned object, this embodiment transmits the two kinds of information to the scanning coil of the magnetic resonance system, so that the scanning coil covers the part to be scanned based on the above information. Among them, based on the three-dimensional body shape features and the part to be scanned, the scanning coil set at the corresponding position in the scanning bed can be determined, and the scanning coil set at the corresponding position can be started to cover the part to be scanned. For example, when the part to be scanned is the head, the head coil set at the corresponding head position of the scanning bed is started to cover the head of the scanned object. When the part to be scanned is the knee joint, the coil set at the corresponding knee joint position of the scanning bed is started to cover the knee joint part of the scanned object. In addition, one or more scanning coils at different positions can be started depending on the number of parts to be scanned of the scanned object. After starting the scanning coils at multiple positions, multiple parts to be scanned of the scanned object can be scanned at the same time.

[0047] In particular, in order to enable the scanning coil to more fully wrap the part to be scanned, and adapt to different body shapes of scanning objects, and different scanning parts of the scanning object, a plastic coil can be used as the scanning coil. The plastic coil refers to a flexible coil made of a flexible substrate and a flexible printed circuit. Based on this, the scanning coil can be molded into different shapes based on different body shapes of scanning objects and different scanning parts, and the molded shape is kept fixed, and after the magnetic resonance scanning is completed, the scanning coil is stretched to release the scanning object. When a plastic coil is used as a scanning coil, the curvature of the scanning coil can be adjusted based on the above-mentioned three-dimensional body shape features and the part to be scanned, so that it can more fully and completely cover the part to be scanned. In addition, an airbag and a pressure sensor can be set in the scanning bed. After the pressure sensor detects the scanning object, the airbag is controlled to inflate or deflate to make the corresponding position of the scanning bed convex or concave, so that after the scanning object lies down on the scanning bed, the bed surface of the scanning bed fits the scanning object more fully, so as to prevent the scanning object from moving the body and affecting the results of the magnetic resonance scanning, and improve the scanning experience. In addition, after the airbag is set in the scanning bed, the inflatable airbag of the scanning bed and the scanning coil can cooperate with each other to fix the scanning part of the scanning object and improve the scanning quality. For example, when performing a magnetic resonance scan of the head, after the scanning object lies down, the bed surface of the scanning bed automatically fills and fixes the head of the scanning object to prevent movement, the lower part of the head coil of the scanning bed is fixed to the scanning bed, and the upper part of the head coil is automatically connected from one side to the other side according to the head contour of the scanning object, covering the entire head of the scanning object for subsequent head magnetic resonance. For another example, when performing a magnetic resonance scan of other parts of the body, after the scanning object lies on the scanning bed based on the guidance prompt, the bed surface of the scanning bed is sunken downward to embed the patient's body into the scanning bed to prevent it from moving, and then the plastic coil is used to cover the part to be scanned according to the three-dimensional body shape characteristics and the part to be scanned of the scanning object.

[0048] Step S230: After the scanning coil covers the part to be scanned, a magnetic resonance scan is performed on the scan object.

[0049] Specifically, after the scanning coil covers the part to be scanned, the scanning bed can be controlled to rise and carry the scanned object into the magnetic resonance scanning area of ​​the magnetic resonance system to perform a magnetic resonance scan on the scanned object and obtain the corresponding magnetic resonance scan image. After the magnetic resonance scan is completed, the scanning bed is controlled to carry the scanned object out of the magnetic resonance scanning area, and the scanning coil is automatically released to lower the scanning bed to facilitate the scanned object to move and get out of bed. Among them, during the magnetic resonance scanning process, when there are multiple scanning parts, the scanning strategy of scanning in sequence or scanning multiple parts simultaneously can be determined based on the needs of the actual application scenario. In addition, before the magnetic resonance scan, based on the information of the part to be scanned, a voice prompt can be given to the scanned object for confirmation, and the scanned object can be guided to lie on the scanning bed.

[0050] Compared with the related art, the scanning technician is required to place the scanning coil and locate the scanning part before the magnetic resonance scanning, and the scanning technology selects the scanning sequence to scan the scanning object, which leads to more manual intervention in the entire magnetic resonance scanning process and low operating efficiency. This embodiment can realize the automated magnetic resonance scanning workflow, complete the magnetic resonance scanning without manual operation, and realize customized scanning for the three-dimensional body features and the part to be scanned of different scanning objects, thereby reducing manual intervention, improving operating efficiency, and saving labor costs compared with the related art.

[0051] In the above steps S210 to S230, the three-dimensional body shape features and the part to be scanned of the scanned object are obtained; based on the three-dimensional body shape features and the part to be scanned, the scanning coil of the magnetic resonance system is controlled to cover the part to be scanned; after the scanning coil covers the part to be scanned, the scanned object is subjected to magnetic resonance scanning. It can control the scanning coil to cover the scanning part for different scanning parts and scanned objects of different body shapes, thereby solving the problem of more manual intervention and low operation efficiency in the scanning process.

[0052] Further, in one embodiment, based on the above step S210, obtaining the three-dimensional body shape features and the part to be scanned of the scanned object may specifically include:

[0053] The scanning object is three-dimensionally scanned to obtain the three-dimensional body shape features of the scanning object; the part to be scanned of the scanning object is determined according to the three-dimensional body shape features of the scanning object. Among them, the scanning object can be three-dimensionally scanned by a three-dimensional scanner, and the three-dimensional body contour of the scanning object is reconstructed based on the obtained point cloud data to obtain the three-dimensional body shape features. The three-dimensional scanner is a scientific instrument used to detect and analyze the appearance data such as the shape and color, surface albedo, etc. of an object or environment. In addition, the three-dimensional scanner can be integrated with a height measuring instrument and a weight measuring instrument into a measurement system, so that the height and weight can be measured at the same time as the three-dimensional scanning, so as to improve the efficiency of the preceding scanning measurement. In this embodiment, by pre-scanning the scanning object in three dimensions based on the three-dimensional scanner before the magnetic resonance scanning to obtain its three-dimensional body shape features, the contour and structural characteristics of the scanning object can be accurately obtained, thereby providing accurate data reference for the subsequent customized magnetic resonance scanning. In addition, this embodiment determines the part to be scanned based on the three-dimensional body shape features of the scanning object, and can also achieve accurate positioning of the part to be scanned.

[0054] Furthermore, in one embodiment, determining the to-be-scanned part of the scanned object according to the three-dimensional body shape feature of the scanned object may include:

[0055] According to the three-dimensional body shape features of the scanned object, the part of the scanned object to be scanned is determined with reference to the prior information characterizing the distribution positions of the organs of the human body. After obtaining the three-dimensional body shape features, the distribution positions of the organs of the human body in the human body are matched with the three-dimensional body shape features, so that it can be determined at which part of the scanned object the organ that needs to be scanned by magnetic resonance is located. Based on this, this embodiment can realize the accurate positioning of various tiny organs of the human body and improve the accuracy of magnetic resonance scanning.

[0056] Optionally, in one embodiment, based on the above step S220, based on the three-dimensional body shape feature and the part to be scanned, controlling the scanning coil of the magnetic resonance system to cover the part to be scanned may specifically include:

[0057] The scanning coil in the scanning bed of the magnetic resonance system is controlled, and the coil shape of the scanning coil is adjusted according to the three-dimensional body shape characteristics and the part to be scanned, until the scanning coil covers the part to be scanned. In this embodiment, the coil shape of the scanning coil is adjusted according to the three-dimensional body shape characteristics and the part to be scanned of the scanned object, specifically, the bending curvature and the wrapping range of the scanning coil are adjusted so that the scanning coil covers the part to be scanned. Preferably, scanning coils for scanning different parts can be set at different positions of the scanning bed, and the scanning coils at the positions corresponding to the part to be scanned in the scanning bed are controlled based on the part to be scanned, so that the bending curvature and the wrapping range are adjusted according to the three-dimensional body shape characteristics of the scanned object until the part to be scanned is covered. Therefore, this embodiment can control the operation of the corresponding scanning coil based on the scanned object with different three-dimensional body shape characteristics and the different parts to be scanned of the scanned object, and adapt the three-dimensional body shape characteristics and the part to be scanned of the scanned object to realize customized magnetic resonance scanning.

[0058] Furthermore, if the to-be-scanned knee joint of the scanned object corresponds to the middle section of the scanning bed, the scanning coils in the corresponding middle section of the scanning bed are controlled to cover the to-be-scanned portion; if it is determined that the to-be-scanned knee joint of the scanned object corresponds to the area closer to the tail end of the scanning bed, the scanning coils in the corresponding area closer to the tail end are controlled to cover the to-be-scanned portion. Thus, this embodiment can realize customized magnetic resonance scanning according to the three-dimensional body shape features of the scanned object and the to-be-scanned portion.

[0059] In addition, in one embodiment, the scanning coil is a plastic coil. In this embodiment, by using the plastic coil as the scanning coil, the scanning coil can more fully and completely cover the scanning coil based on the specific three-dimensional body shape characteristics of the scanned object and different parts to be scanned, thereby improving the accuracy of subsequent magnetic resonance scanning.

[0060] In addition, in one embodiment, based on the above step S230, after the scanning coil covers the part to be scanned, performing magnetic resonance scanning on the scanned object may include:

[0061] After the scanning coil covers the part to be scanned, the scanning bed of the magnetic resonance system is controlled to carry the scanning object into the magnetic resonance scanning area to perform magnetic resonance scanning on the scanning object. The magnetic resonance scanning area refers to the magnet center of the magnetic resonance system. In this embodiment, after the scanning coil covers the part to be scanned, the scanning bed carrying the scanning object can be controlled to rise and enter the magnetic resonance scanning area to start the subsequent magnetic resonance scanning process, thereby reducing manual intervention in the magnetic resonance scanning process and improving the efficiency of magnetic resonance scanning.

[0062] In addition, in one embodiment, the control method of the magnetic resonance system may further include:

[0063] After the MRI scan is completed, the scanning bed is controlled to carry the scanned object out of the MRI scan area and release the scanning coil. After the MRI scan is completed, the present embodiment controls the scanning bed to carry the scanned object out of the MRI area, releases the scanning coil covering the body part of the scanned object, and restores the raised scanning bed to its original height to facilitate the scanned object to move and get out of bed. Thus, the present embodiment can reduce manual intervention in the complete MRI scanning process and improve the efficiency of the overall MRI scanning.

[0068] Step S303, based on the three-dimensional body shape features of the scanned object and the part to be scanned, controlling the scanning coil to cover the part to be scanned of the scanned object;

[0069] Step S304, after the scanning coil covers the part to be scanned, the scanning bed is controlled to rise and carry the scanned object into the magnetic resonance scanning area;

[0070] Step S305, determining the scanning strategy according to the part to be scanned, that is, scanning in sequence or scanning multiple parts simultaneously;

[0071] Step S306, after the magnetic resonance scanning is completed, the scanning bed is controlled to carry the scanned object to leave the magnetic resonance scanning area, and the scanning coil is released to lower the scanning bed.
