In some embodiments, the processing device may acquire coil positions of a scanning imaging coil used to scan a target object; and detecting user operation on the operation control to determine whether to display the coil position in the scanned image. In some embodiments, processing device 120 may process data, information, and/or processing results obtained from other devices or system components and execute program instructions based on the data, information, and/or processing results to perform one or more functions described herein. For example, the processing device 120 may receive user operations on the operation controls from the terminal device 130, and display coil positions and the like in the scan configuration interface of the imaging device 110. In some embodiments, the processing device 120 may be a single server or a group of servers. The server group may be centralized or distributed.

For example, the scenario 100 may also include a database. As another example, the scenario 100 may implement similar or different functionality on other devices. However, such changes and modifications do not depart from the scope of the present application.
FIG. 2 is an exemplary flow chart of an exemplary coil display method, shown in accordance with some embodiments of the present description. In some embodiments, flow 200 may be performed by a processing device (e.g., processing device 120). For example, the process 200 may be stored in a storage device (e.g., an onboard storage unit of a processing device or an external storage device) in the form of a program or instructions that, when executed, may implement the process 200. As shown in fig. 2, the process 200 may include the following steps.
The target object may include a patient or other medical test object (e.g., other animal such as a laboratory white mouse), etc. The target object may also be part of a patient or other medical subject, including organs and/or tissues, such as the heart, lungs, ribs, abdominal cavity, etc.
Imaging coils are an important component of the functional implementation of imaging devices. Taking the magnetic resonance imaging apparatus as an example, the magnetic resonance imaging apparatus mainly includes a magnet, an imaging coil, a receiving link, and the like. The imaging coils may include gradient coils, radio frequency coils, receive coils, and the like, among others. A uniform static magnetic field is generated by a superconducting magnet, a radio frequency transmitting coil excites hydrogen nuclei to spin to generate magnetic resonance signals, and spatial information encoding is carried out on the signals by using a gradient coil. The magnetic resonance signals are collected by a radio frequency receiving coil, converted into digital signals through a receiving link, and finally reconstructed by a computer to obtain a magnetic resonance image. The coil is an important component of the magnetic resonance system and has a decisive effect on the image quality of the magnetic resonance system. In some embodiments, the imaging coils may include one or more of gradient coils, video coils, receive coils, and the like.
The coil position may refer to the relative position of the imaging coil to some reference. For example, the position of the imaging coil compared to the scanning bed, the position of the imaging coil compared to a target object located on the scanning bed, or the position of the imaging coil compared to other objects, etc.
In some embodiments, the coil position may be represented by position coordinates. For example, the coil position may be determined based on spatial coordinates of the geometric center of the imaging device. For example, a spatial coordinate system may be established based on the geometric center of the imaging device, the coordinates of the geometric center may be set to (0, 0), and when the imaging coil of the imaging device moves, the spatial coordinates of the imaging coil (which may be determined by its geometric center, e.g., the center of mass coil, etc.) may be within the spatial coordinate system set with the geometric center of the imaging device as the origin, e.g., the spatial coordinates of the imaging coil may be (30, 50, 60).
In some embodiments, the imaging coil used to scan the target object may be one or more of a plurality of coils of an imaging device, e.g., one or more radio frequency coils, receive coils, etc. In some embodiments, the imaging coil may be a certain segment or several segments of a certain coil of the imaging device selected by the user.
In some embodiments, the user may adjust the position of the imaging coil to place the imaging coil in a different position for a more accurate scan.
In some embodiments, the coil position may be determined based on a control system of the imaging device, for example, the control system may record position coordinates for each movement of the coil.
In step 220, the operation of the operation control by the user is detected to determine whether to display the coil position in the scanned image. In some embodiments, step 220 may be performed by the coil position display module 520.
The user may be an operator of the imaging device. Such as a doctor, researcher, etc. The operation control may be a button, a checkbox, an input box, a draggable scanning point, etc. of an operation interface of the imaging device. In some embodiments, the user may perform the operation on the operation control in various ways, for example, touch, voice, gesture, operation of an external device (mouse, keyboard, etc.), and the like.
The scan image may refer to an image generated based on signals acquired by an imaging coil after a scan of a target object is performed by an imaging device. For example, an image obtained by image reconstruction based on the imaging signal.
In some embodiments, the processing device may detect user operation of the operation control based on whether a corresponding operation instruction is received. For example, whether the operation space of the coil position is displayed in the scanned image may be similar to "whether the coil position is displayed in the scanned image is yes/no" operation space, the user selects "yes", then an instruction to display the coil position in the scanned image may be triggered, and the user selects "no", then an instruction to not display the coil position in the scanned image may be triggered. In some embodiments, the user may perform the operation on the operation control by selecting, switching, dragging, voice inputting, or the like.
In response to a user's manipulation of the manipulation control, when the coil position needs to be displayed in the scan image, the processing device may display the position of the imaging coil at the time of scanning relative to the target object in the scan image. In some embodiments, displaying the coil position may indicate the coil position in various ways, such as by solid lines, dashed lines, boxes, arrows, and so forth. In some embodiments, the boundaries of the display coils in the scanned image may be used as coil locations. The boundaries of the coils are displayed in a manner that avoids obscuring the tissue structure of the target object in the scanned image.
In some embodiments, the scanned image may be a two-dimensional image or a three-dimensional image, which is not limited in this specification.
In some embodiments, the coil display method may further include step 230 of detecting a user operation of the operation control to determine whether to display the coil position in the configuration interface before scanning. In some embodiments, step 230 may be performed by the coil position display module 520.
The pre-scan configuration interface may be a configuration interface of a scan protocol prior to scanning the target object. In some embodiments, the scan protocol may include a plurality of parameters, e.g., scan parameters, reconstruction parameters, and the like. In some embodiments, the scan protocol may include scan time, signal-to-noise ratio, number of excitations, spatial resolution, repetition time, readout signal pattern, etc., or any combination thereof. In some embodiments, the scan protocol may be stored in a storage device and/or an external data source.
In some embodiments, the processing device may determine whether to display the coil position in the pre-scan configuration interface based on user operation. For example, the processing device performs the corresponding operation in response to the user checking a dialog box of "display coil position in configuration interface before scanning", clicking a dialog box of "display coil position in configuration interface before scanning", pressing a button of "display coil position in configuration interface before scanning", uttering a related voice of "display coil position in configuration interface before scanning", performing a gesture action related to "display coil position in configuration interface before scanning", and the like.
In some embodiments, when the user sets, by operating the control, that the coil position is not displayed in the configuration interface, the coil position may not be indicated on the model structure of the target object displayed in the configuration interface. Illustratively, reference may be made to fig. 6A and 6B, with fig. 6A being an exemplary schematic diagram showing no coil positions in the configuration page according to some embodiments of the present description, and fig. 6B being an exemplary schematic diagram showing coil positions in the configuration page according to some embodiments of the present description. Wherein the dashed boxes in fig. 6B represent the coil positions of the scanning coils.
In some embodiments of the present description, whether to display the coil position in the configuration interface before scanning and/or the scanned image is realized based on user requirements, so that the experience requirements on an operator can be reduced, the scanning accuracy can be improved, the quality of the scanned image can be improved, the coil visualization characteristics can be increased, the use right of a user can be enriched, the coil virtualization can be realized, and a technician or a research and development staff can be helped to analyze the image quality more intuitively and conveniently.
Fig. 3 is an exemplary flow chart illustrating an exemplary determination of whether a coil position matches a scan location according to some embodiments of the present description. In some embodiments, flow 300 may be performed by a processing device. For example, process 300 may be stored in a storage device (e.g., an onboard memory unit of a processing device or an external storage device) in the form of a program or instructions that, when executed, may implement process 300. As shown in fig. 3, the process 300 may include the following steps:
The scanning site may include organs and/or tissues of the target object, e.g., heart, lungs, ribs, abdominal cavity, etc.
Matching may refer to the current coil position being able to cover the scanning site of the target object. For example, a coverable is considered a match; if not, it is considered as not matched. For example, when scanning the heart of the target object, when the coil completely covers the heart region of the target object, it can be determined that the coil position matches the position of the scanning portion.
In some embodiments, the processing device may determine whether the coil position matches the position of the scanning site in a number of ways. For example, the processing device may acquire information of the target object on the scanning bed, such as height, lying position, and the like, by laser radar scanning, infrared ranging, and the like, estimate position coordinates of the scanning portion in a spatial coordinate system having the center of the imaging device as an origin of coordinates based on the information, and determine whether the coil position matches the position of the scanning portion based on the position coordinates and the position coordinates (coil position) of the imaging coil. For another example, the processing device may acquire a positioning image of the target object and determine whether the coil position matches the position of the scanning site based on the positioning image. For more explanation on determining whether the coil position matches the position of the scanning site based on the positioning image, reference may be made to fig. 4 and its associated description.
In some embodiments, when it is determined that the coil position matches the position of the scanning portion, a subsequent process, for example, a scanning process or the like, may be performed; when it is determined that the coil position does not match the position of the scanning portion, step 320 may be performed.
In response to the coil position not matching the position of the scanned part, a prompt is issued to the user, step 320.
In some embodiments, the prompt may be used to inform the user of information related to the coil position. For example, the prompt may include informing the user that the coil position needs to be adjusted and/or the coil selected again. As another example, the prompt may include informing the user that the current coil position matches the position of the scanned part, whether to enter a follow-up procedure, or the like. It can be understood that there may be various reasons for the mismatch between the coil position and the scanning portion, for example, the operator may not select the coil section properly (for example, the selected coil is too small or the selected coil position has a limited moving range and cannot cover the scanning portion), the position of the coil is not placed accurately enough, and the like. In some embodiments, the processing device may also directly issue prompts to the user to adjust the coil position and to reselect the coil, with the user selecting at his or her discretion whether to reselect or adjust the coil position.
In some embodiments, the types of prompts may include image prompts, text prompts, voice prompts, vibration prompts, and the like.
In the embodiment, by judging whether the coil position is matched with the scanning part or not and sending a prompt to a user, the experience requirement on an operator can be reduced, the coil can be accurately placed, and the problems that the image signals are unevenly distributed, the signal to noise ratio is reduced and the like due to the fact that the coil deviates from the scanning part are avoided.
FIG. 4 is another exemplary flow chart illustrating the determination of whether a coil position matches a scan location according to some embodiments of the present description. In some embodiments, flow 400 may be performed by processing device 120. For example, the process 400 may be stored in a storage device (e.g., an onboard storage unit of a processing device or an external storage device) in the form of a program or instructions that, when executed, may implement the process 400. As shown in fig. 4, the process 400 may include the following steps:
The scout image may refer to an acquired image including the scanning bed and the target object. For example, an image of a target object located on a scanning bed. The positioning image may be used to enable positioning of the scanning site in a scanning examination, i.e. to determine the corresponding position of the planned scanning range on the target subject's body structure. In some embodiments, the positioning image may be obtained by shooting with a camera, positioning and scanning, and the like.
Based on the positioning image, the position of the scanning portion in the positioning image is determined 420.
The position of the scanning location in the image may refer to a location area of the scanning location in the scout image. In some embodiments, the location may correspond to a target object's anatomical location to more accurately determine the scan site.
In some embodiments, the processing device may determine the location of the scanning site in the scout image by means of image recognition. For example, the processing device may invoke a trained image recognition model, and determine the position of the scanning part in the positioning image through the image recognition model.
In some embodiments, the image recognition model may be a machine learning model. Such as deep neural network models, convolutional neural network models, and the like. The input of the image recognition model can be a positioning image and a scanning part, and the output can be a recognition frame of the scanning part in the positioning image, and the recognition frame can frame the region position of the scanning part in the positioning image. In some embodiments, the initial model may be trained on sample data to obtain an image recognition model. The sample data may include a training sample and a corresponding label, the training sample may be a sample positioning image, and the label is a position of the scanning part in the sample positioning image. The labels may be obtained by manual labeling or other methods, and the training method may be various common training methods, such as a gradient descent method.
Based on the position of the scanning site in the scout image, it is determined whether the coil position matches the position of the scanning site, step 430.
In some embodiments, the processing device may determine whether the coil position matches the position of the scanning portion based on the position of the scanning portion in the positioning image and the coil position in a manner of determining whether the coil covers the scanning portion. For example, when the scanning part is the abdomen, part of the coil is found to be positioned above the abdomen of the target object through the coil position, but the abdomen cannot be completely covered, and the coil is judged not to cover the scanning part; for example, when the scan site is a brain and the coil position is located in the brain, but the coil size is small and the brain cannot be completely covered, it is determined that the scan site is not covered by the coil.
In some embodiments, the processing device may establish a mapping relationship between the positioning image and the spatial coordinates established based on the center of the imaging device, and determine the spatial coordinates corresponding to the scanning position in the current positioning image. It is further determined whether the coil position matches the position of the scanning portion based on the position coordinates corresponding to the scanning portion and the position coordinates of the imaging coil.
In the embodiment, by acquiring the positioning image and judging whether the coil position is matched with the scanning part in an image recognition mode, an operator can be prevented from judging according to experience, the influence of artificial subjective factors is reduced, and the accuracy of the coil placement position is improved.

The coil position display module 520 may be used to detect user manipulation of the manipulation controls to determine whether to display the coil position in the scanned image.
The coil position display module 520 may also be configured to detect user operation of the operation control to determine whether to display the coil position in the pre-scan configuration interface.
In some embodiments, the coil display system 500 may further include a determination prompting module 530 for determining whether the coil position matches the position of the scanning portion of the target object; in response to the coil position not matching the position of the scanning site, a prompt is issued to the user.
It should be noted that the above description of the coil display system 500 and the modules thereof is for convenience of description only and should not limit the present disclosure to the scope of the illustrated embodiments. It will be appreciated by those skilled in the art that, given the teachings of the present system, any combination of modules or sub-system configurations may be used to connect to other modules without departing from such teachings. In some embodiments, the modules may be different modules in one system, or may be one module to implement the functions of two or more modules. For example, each module may share one memory module, and each module may have its own memory module. Such variations are within the scope of the present disclosure.
Some embodiments of the present description also relate to a coil display apparatus including a processor for performing the coil display method.
Some embodiments of the present description also relate to a computer-readable storage medium storing computer instructions, wherein when the computer instructions in the storage medium are read by a computer, the computer executes the coil display method.
The beneficial effects that may be brought by the present application include but are not limited to: (1) reduced requirements for operator experience. If the operator does not have accurate knowledge of the exact location of the scanned area, the coil placement can be determined to be accurate by displaying the coil location. If the coil is not placed accurately, the configuration interface can display the prompt of the wrong placement of the coil, so that the scanning time of a technician is saved, and the scanning efficiency is improved; and (2) improving the scanning accuracy. The accuracy of the scanning position is ensured by accurately displaying the coil position, so that the condition that rescanning is needed due to inaccurate coil position is avoided; and (3) improving the quality of the scanned image. The accurate placement of the coil avoids the problems of uneven distribution of image signals, reduced signal-to-noise ratio and the like caused by the deviation of the coil from a scanning part in an image; (4) The coil visualization characteristic is increased, and the option of an operator is enriched. An operator can select whether the coil position needs to be displayed according to the habit and the preference of the operator, so that the coil position can be displayed on an operation interface or an imaging interface; (5) The coil virtualization is realized to help a technician or a patient to know coil position information and to help a doctor or the patient to analyze image quality reasons. More convenience and operability are provided for self-service scanning in the future; (6) The image quality is analyzed more intuitively and conveniently by technicians or developers. When the image quality is not good, the relative relation between the coil and the scanning part can be seen in the scanned image, so that whether the image quality is related to the coil placement position or not can be analyzed more conveniently. It is to be noted that different embodiments may produce different advantages, and in different embodiments, any one or combination of the above advantages may be produced, or any other advantages may be obtained.
