The medical imaging technology is widely applied to the clinical diagnosis process, and various medical imaging devices can reflect the information of a scanned object from different sides. Multiple modes of imaging or multiple times of imaging in the same modality are performed on the same scanning object clinically, and the information is fused with each other, so that the information provided by images in different modalities can be verified mutually.
The embodiment provides a multi-modal medical scanning system attenuation information display method. Fig. 1 is a flowchart of a multi-modality medical scanning system attenuation information display method according to an embodiment of the application, and as shown in fig. 1, the flowchart includes the following steps:
step S101, a first image of a scanned object is acquired, where the first image is a first modality scanned image of the scanned object, and the first modality scanned image is an anatomical image.
In this embodiment, according to different clinical needs, the scanning object may be a human body, an animal, or an experimental phantom, and the first image may be a CT scout image; the scan object may also be a designated region, such as a specific part of the body, for example, the head, the chest, the abdomen, etc., or a combination thereof, and the first image is a CT image of the designated region, which is not particularly limited in this application.
The multi-modality medical scanning system comprises a PET/CT, a PET/MR, a SPECT/CT, a SPECT/MR and other hybrid imaging systems, and the hybrid imaging systems can acquire data of multiple modalities simultaneously and respectively generate medical images of the modalities. In a multi-modality medical scanning system, medical images are classified into anatomical images and functional images according to their functions, and the anatomical images can provide the functional images with imaging tissue attenuation information and structural information of fused images at the time of diagnosis. The anatomical image can be obtained by radiography, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), ultrasound imaging (US), magnetic resonance angiography (DSA), and the like, and can be used to describe morphological information of a scanned object; the functional image can be obtained through Positron Emission Tomography (PET), Single Photon Emission Computed Tomography (SPECT), functional magnetic resonance imaging (fMRI) and the like, and can be used for describing the functional and metabolic information of a scanned object.
And S102, displaying the first image on an interactive interface of the multi-modal medical scanning system.
As shown in fig. 2, in the present embodiment, the multi-modality medical scanning system can interact with the user through an interactive interface. The interactive interface can be realized on various terminal devices with display interfaces. The interactive interface may present data (e.g., scan data, analysis results) acquired or generated via the multi-modal medical scanning system, and may also display a scan image, such as a first image, representing a target object. In some embodiments, the interactive interface may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), and the like, and the present embodiment does not limit the type of the Display interface. In some embodiments, the touch panel may cover the interactive interface, and when the interactive interface can accept the input or touch operation of the user, a corresponding visual output display is provided on the interactive interface.
Step S103, displaying attenuation information marks on an interactive interface of the multi-modal medical scanning system, wherein the attenuation information marks correspond to attenuation information sources; the attenuation information mark is displayed in a non-overlapping or non-partially overlapping manner with the first image.
In medical imaging procedures, image reconstruction is often required in conjunction with attenuation information. Attenuation information is the energy intensity loss generated when X-rays or gamma rays pass through a substance, and has an important influence on the quality of an image. In the image reconstruction process, when a scanning object is scanned, scanning is performed by using corresponding scanning parameters to obtain original scanning data, attenuation information of tissue imaging can be obtained according to the original scanning data, and then image reconstruction is performed by combining the attenuation information to obtain a scanning image.
In this embodiment, generally, different scanning objects have different information characteristics such as scanning positions and scanning thicknesses, and attenuation information obtained by scanning is different. The source of attenuation information may be identified by attenuation information markers, thereby facilitating user selection and editing of attenuation information during image reconstruction.
In this embodiment, the display form of the attenuation information mark includes one or a combination of several of graphic display, pattern display, text display and color display. The attenuation information mark is displayed in a non-overlapping or non-partially overlapping manner with the first image. Wherein the non-overlapping display means that the attenuation information mark is not completely stacked on the first image; the non-partial overlap display means that the attenuation information mark is not partially superimposed on the first image. For example, as shown in fig. 2, in some embodiments, the interactive interface may present, outside the first image, a display object having a selection bar, the display object being a rectangular box, in which attenuation information indicia corresponding to respective attenuation information sources are presented: a first positioning frame 11, a second positioning frame 12, air and a bed board. In other embodiments, the size and the position of the attenuation information mark can be mapped with the first image, so that the first image and the attenuation information can be visually displayed, and simple, convenient and quick attenuation information matching setting is realized.
Of course, in other embodiments, the attenuation information mark may have different presentation forms and different presentation positions, and the present application is not particularly limited.
In summary, according to the attenuation information display method of the multi-modal medical scanning system provided by the embodiment of the application, the first image is displayed on the interactive interface of the multi-modal medical scanning system, the attenuation information mark is displayed on the interactive interface of the multi-modal medical scanning system, and the attenuation information mark corresponding to the attenuation information source is displayed in a non-overlapping manner or in a non-partially overlapping manner with the first image, so that a user can conveniently identify the source of the attenuation information on the interactive interface, and the operation efficiency is improved.
The embodiments of the present application are described and illustrated below by means of preferred embodiments.
On the basis of the above embodiments, in one embodiment, a second scanning range 13 is displayed on the interactive interface, where the second scanning range 13 is a data acquisition range of a second modality scanning image of the multi-modality medical scanning system, and the second modality scanning image is a functional image. Optionally, in this embodiment, the second scanning range is represented by a rectangular frame.
In the present embodiment, a CT scout image of a scanning object may be acquired by the first modality scanning device, so as to determine a scanning range and a range for image reconstruction by the CT scout image. After obtaining the CT locating image of the scanned object, setting the scanning range of the CT tomographic image on the CT locating image, and then executing sequential scanning according to the scanning range of the CT tomographic image to obtain the attenuation information of the imaging tissue.
It should be noted that the functional image reconstruction needs to be combined with attenuation information of the imaged tissue. Therefore, the range of the attenuation information source is larger than the second scanning range, so that the scanning data obtained in the second scanning range can be used for functional image reconstruction.
On the basis of the above embodiments, in one embodiment, the image reconstruction range of the functional image is displayed on the interactive interface.
In this embodiment, scan data is acquired based on the second scan range, and functional image reconstruction is performed based on the scan data and the image reconstruction range of the functional image. In the process of image reconstruction, attenuation correction data can be provided for image reconstruction by acquiring attenuation information corresponding to all attenuation information sources in the second scanning range, image artifacts are reduced, the problems of inaccuracy of SUV (standard uptake value) of an image and the like are solved, and the image quality is improved.
On the basis of the above embodiments, in one embodiment, the attenuation information mark displays an attenuation information source selection list in response to an input operation.
As shown in fig. 2-3, in the present embodiment, the attenuation information flag is used to expand and display the attenuation information source list after receiving the operation instruction, so as to facilitate the selection and editing of the attenuation information source. The operation instruction can be an input operation, and can also be a click operation, a drag operation or other self-defining operations. The source of attenuation information includes at least one of a first modality scan image, a second modality scan image, and a medium having an attenuation effect on X-rays or gamma-rays. Specifically, the first modality scan image and the second modality scan image may be one or more positioning frames corresponding to a scan object, such as the first positioning frame 11, the second positioning frame 12, or the first positioning frame and the second positioning frame (11+ 12); the medium having an attenuation effect on X-rays or gamma-rays may be air, a bed plate, or other objects, and the present application is not particularly limited. Preferably, the first modality scan image is one of a CT image and an MR image, and the second modality scan image is a PET image.
In some embodiments, the attenuation information markers may be linked with corresponding attenuation information sources, and the corresponding attenuation information sources may be processed by highlighting, deleting, or other predefined operations (e.g., attenuation information may be edited by adjusting the size and position of the attenuation information markers) of the attenuation information markers.
On the basis of the above embodiments, in one embodiment, the method further includes: an attenuation information source in the selected list of attenuation information sources is obtained, and a first modality image scan is performed according to the selected attenuation information source.
As shown in fig. 4, in the present embodiment, when the range of the attenuation information source is smaller than the second scanning range. If the scan region (the sum of the ranges of the third positioning frame 21 and the fourth positioning frame 22) selected by the scout image in the first modality scan image does not completely cover the data acquisition range (the second scan range 23) of the second modality scan image, a portion of the second scan range 23 has no attenuation information, and the scan data acquired by the portion of the region cannot be used for reconstruction of the second modality scan image. Therefore, all attenuation information of the second scan range 23 needs to be acquired before the second modality scan image reconstruction is performed.
When the attenuation information missing region 24 exists in the second scanning range, the first modality image scanning needs to be performed on the selected attenuation information source, and the attenuation information of the attenuation information missing region 24 is supplemented, so that the scanning data in the second scanning range can be used for reconstructing the second modality scanning image. In order to reduce the radiation dose of the scanned object, the present embodiment does not perform the first modality image scanning again for the range in which the attenuation information exists in the second scanning range, and performs the first modality scan-in only for the attenuation information missing region 24. Compared with the conventional method of performing whole-body first modality scanning on the scanning object in the related art, the method avoids that the whole-body scanning on the scanning object causes more radiation quantity received by the patient and causes additional radiation damage to the body. It can be understood that, on the interactive interface, the attenuation information source which does not execute the first-mode scanning may be highlighted or information-prompted to remind the user to perform the first-mode supplementary scanning in time.
In one embodiment, the attenuation information markers correspond to the attenuation information sources one to one.
In this embodiment, the interactive interface may present a display object having a tab in which attenuation information indicia corresponding to various attenuation information sources are presented. In some embodiments, the correspondence between the attenuation information markers and the attenuation information sources may be predetermined, for example, one attenuation information marker may be set to correspond to a plurality of attenuation information sources or different combinations of at least two attenuation information sources. In other embodiments, attenuation information marks can be set to correspond to the attenuation information sources one by one, so that a user can conveniently select the attenuation information marks in a user-defined mode.
It should be noted that the steps illustrated in the above-described flow diagrams or in the flow diagrams of the figures may be performed in a computer system, such as a set of computer-executable instructions, and that, although a logical order is illustrated in the flow diagrams, in some cases, the steps illustrated or described may be performed in an order different than here.
