All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a flowchart of a medical imaging method according to an embodiment of the present invention. The technical scheme of the embodiment is suitable for the condition that the scanning protocol parameters of the medical imaging system are determined through the template images. The medical imaging system may be a magnetic resonance imaging system, a CT (Computed Tomography, abbreviated as CT), a Positron Emission Tomography (PET), an X-ray imaging device, and the like, and the template image may be a corresponding magnetic resonance template image, a PET image, a CT image, and/or a DR (Digital Radiography, abbreviated as DR) image, and the like. The method can be executed by a medical imaging device provided by the embodiment of the invention, and the device can be realized in a software and/or hardware manner and is configured to be applied in a processor of a medical imaging system. The method specifically comprises the following steps:
s101, determining a template image corresponding to the current subject.
The template image corresponds to a scanning protocol parameter, and the scanning protocol parameter at least comprises the combination of all parameters configured by the scanning device for finishing the imaging scanning of the scanning part.
The template image is used for showing the scanning effect of the corresponding scanning device for scanning the specified scanning part of the current detected person by using the corresponding scanning protocol parameter. The historical scanning image of the designated scanning part obtained based on the preset scanning protocol parameters can be used as the template image of the designated scanning part corresponding to the preset scanning protocol parameters. It is understood that the template image has a one-to-one correspondence with the preset scan protocol parameters.
The scanning device may be a scanning device of a magnetic resonance imaging system, a scanning device of a CT imaging system, etc. Taking the scanning device as the scanning device of the magnetic resonance imaging system as an example, the template image is a magnetic resonance image, and the scanning protocol parameters preferably include scanning sequence parameters and magnetic resonance image reconstruction parameters. The magnetic resonance image reconstruction parameters include an image reconstruction method, an image preprocessing method and the like adopted by the magnetic resonance image reconstruction.
In order to more intuitively display the scanning results corresponding to different scanning protocol parameters to the user, a plurality of template images are established or matched for each scanning part, and different template images correspond to different scanning protocol parameters. In order to quickly determine the scanning protocol parameters corresponding to each template image, the corresponding relationship between the template images and the scanning protocol parameters is also established. Specifically, the corresponding relationship between the image identifier of the template image and the scanning protocol parameter is recorded in the mapping table.
It will be appreciated that the imaging system typically has received scan location information for the current subject when determining scan protocol parameters for the current subject. Thus, after the user inputs the scanning protocol request information through the input device, the imaging system can determine the scanning part of the current examinee according to the scanning part information, a plurality of candidate template images are matched for the current examinee according to the determined scanning part and the received scanning protocol request information, and the scanning protocol parameters of each candidate template image are different. The imaging system presents the candidate template image 152 to the user via the configuration interface 151 of the output device 150 (shown in fig. 2A). And inputting image selection information through the input device after the user browses, so that the imaging system determines a candidate template image selected by the user according to the image selection information, and the candidate template image is used as a template image of the current subject. The scan part information is the scout image 153 including the scan part 1531 selected by the user for the current subject, as shown in fig. 2B. The image selection information may be a selection operation such as a click, touch, or the like of the user on the selected candidate template image.
It can be understood that, if the user is familiar with the image identifier of the template image corresponding to the parameters of the common scanning protocol, after the scanning part of the current subject is determined, the image identifier of the required template image is directly input through the input device, and after the imaging system receives the image identifier input by the user, the template image is searched in the database in which the template image is stored according to the image identifier, and then the search result is taken as the template image corresponding to the current subject.
In one embodiment, registration information of the current subject, which may be personal information and information of the organ to be imaged, is typically registered in a console computer of the magnetic resonance imaging system before the current subject is prepared for scanning. Historical information is stored in a local database of the magnetic resonance imaging system and a database of the server side, the historical information can be historical scanning data or historical registration information, and the magnetic resonance imaging system can calculate the matching degree of the registration information of the current examinee and the historical information in the database; if the registration information of the current examinee is completely matched with the historical information in the database, a recommended template image is directly given out in the display, and the template image corresponds to the historical information in the matched database; if the registration information of the current subject is not completely matched with the historical information in the database, a plurality of recommended template images are output according to the matching degree.
Of course, there may not be a scan data packet matching the registration information of the current subject in the history information of the database, and at this time, a corresponding scan data packet needs to be established based on the scan data of the current subject, where the scan data packet at least includes a positioning data packet and a registration data packet. The registration information or the history information in the database may include: personal information of the patient (name, sex, certificate number, etc.), the part to be scanned (heart, head, etc.), the position of the bed after the current subject has entered the patient bore, a calibration image (coronal plane) scanned at this position for confirming the position or location information of the patient relative to the bed, the sequence used for the subsequent scan, and the corresponding location position.
Taking the determination of the positioning data packet of the current subject as an example, as shown in fig. 3, the basic information of the current subject is acquired, searching the local database and the server-side database for a positioning data packet matching the basic information of the current subject, if the position data is searched, determining whether the scanning part of the current detected object is the same as the scanning part in the searched positioning data packet, if so, scanning a calibration positioning image for the current detected object, matching the calibration positioning image with the positioning image in the positioning data packet, determining a protocol to be scanned according to the matching result, if the protocol to be scanned is consistent with the scanning protocol corresponding to the positioning data packet, the protocol to be scanned is directly used for imaging scanning of the current examinee, and if the current subject is inconsistent with the current subject, acquiring a positioning image of the current subject according to a conventional magnetic resonance scanning process so as to update the positioning data packet of the current subject. If the local database and the server-side database do not search the positioning data packet matched with the basic information of the current examinee, or the positioning data packet matched with the basic information of the current examinee is searched, but the scanning part corresponding to the positioning data packet is different from the scanning part of the current examinee, the position of the sickbed of the current examinee is recorded, a calibration positioning image is scanned for the current examinee, then the positioning image of the current examinee containing the scanning part is obtained according to the conventional magnetic resonance scanning process, and the positioning data packet of the current examinee is established and stored.
Illustratively, the positioning information of the current subject matches the positioning information in the positioning data packet, but the scanning location is different from the scanning location in the positioning data packet, when the positioning data packet in the scanning data packet is established: 1) registering personal information of the patient and the scanned part; 2) after a patient is led into the aperture of the patient, scanning a scout image of a coronary surface by using a scout sequence recommended by a database to be used as a calibration scout image, and recording the calibration scout image and the position of a sickbed; 3) the subsequent scanning is carried out in a common nuclear magnetic resonance scanning process, and the executed sequence protocol and the corresponding scanning position coordinate are recorded in the scanning process; then, in the local client, the information recorded in 1), 2), and 3) is organized according to the same structure, and then stored in the local patient positioning database of the magnetic resonance system, and uploaded to the data of the server through the network, as shown in fig. 4.
Illustratively, the positioning information of the current subject does not match the positioning information of the searched positioning data packet, but the scanning part of the current subject is the same as the scanning part in the positioning data packet, when the positioning data packet in the scanning data packet is established: 1) scanning a calibration scout image of a coronal plane; 2) comparing the calibration positioning image of the scanning with the positioning image in the positioning data packet; 3) and adjusting the position of the sickbed according to the comparison result to ensure that the positions of the examinees are completely consistent relative to the center of the magnet during two scans. Alternatively, the comparison method may be performed both manually and automatically. As shown in fig. 5, the two images are imported into the magnetic resonance human-computer interaction interface, the calibration positioning image of this time is adjusted through translation operation to be consistent with the positioning image in the positioning data packet, and the hospital bed can be automatically adjusted in a linkage manner in the adjustment process.
In one embodiment, the database stores historical scanning protocols, historical scanning scout images, and template images corresponding to the historical scanning protocols, and the scout image of the patient (the contour image of the patient scan) may be first obtained, the scout image of the current patient may be matched with the historical scanning scout images, and the template images corresponding to the plurality of historical scanning protocols with higher matching degrees may be directly displayed on the display. Fig. 6 shows 18 template images matched from the scout image of the patient, and a representative image of each template image, so that the user can select a desired template image as desired, each template image corresponding to a scanning protocol. Preferably, the user can select a desired template image from the displayed representative images of each template image and select the template image through the input device to view the other images in the target image. The scanning protocol may be an FID-like sequence including a partially saturated sequence, a spin echo-like sequence including a spin echo and a fast spin echo, a gradient echo-like sequence including a conventional gradient echo sequence, a spoiled gradient echo sequence, and a steady state precession imaging sequence, or a hybrid sequence formed by a fast spin gradient echo and a plane echo imaging sequence.

The user can click the corresponding template image according to clinical requirements, and the magnetic resonance system can execute the corresponding scanning protocol according to the selected template image.
The matching mode of the scout image of the current examinee and the scout image in the database comprises the following steps: respectively segmenting the scout image of the current examinee and the scout image in the database to generate a plurality of sub-images; performing feature extraction from a sub-image of a scout image of a current patient to construct a current subject feature vector; extracting the characteristics of the sub-images of the positioning images in the database to construct a historical characteristic vector set; and calculating the similarity between the feature vector of the current examinee and the elements in the historical feature vector set, so as to obtain the matching degree between the scout image of the current examinee and the scout image in the database.
