Description
Technical Field
The present invention relates to the technical field of medical imaging and/or therapy systems, and in particular, to a method, a system and a storage medium for positioning a medical imaging and/or therapy system.
Background
In the prior art, when medical image scanning is performed, once a scanning plan is made, the position of a sickbed cannot be changed in the scanning process. However, the well-determined whole-body scan plan often cannot ensure that the central position of the bed is the central position of the organ of interest, and when the multi-medical image scanning device for the bed performs synchronous scan acquisition, the multi-medical image scanning device is limited to the position of the bed which cannot be moved, and the scanning device with a smaller field of view (FOV) cannot always cover the complete organ.
An obvious example is a PET/MR system in which the scan fields of view of PET and MR are set in association when a PET (positron emission computed tomography, positron Emission Computed Tomography, PET)/MR (magnetic resonance imaging, magnetic Resonance, MR) body scan is performed, and the product manual states that its product "follow-up MR protocol will be incorporated into a protocol block by duplication reference with the ac+pet protocol. All protocols of this protocol block have the same isocenter. "As yet another PET/MR system, the product manual states that its product" the PET/MR system is not capable of moving its platform while scanning simultaneously. When the PET/MR system scans simultaneously, the MR scanning is to scan the central position (MR scans simultaneous with PET must not cause the table to move All simultaneous MR scans are locked to the center of the PET bed to which they belong) of the sickbed fixedly. When a synchronous MR acquisition is performed on a certain bed, the PET scan field of view is large, and can completely cover the whole viscera, but the MR scan set in association with the PET scan field of view is limited to the position of the bed which cannot be moved, but often cannot cover the whole viscera (e.g., the upper edges of the liver and the kidney are cut off).

Description of the embodiments

Advantages and features of the invention will become more apparent from the following description and from the claims. It is noted that the drawings are in a very simplified form and use non-precise ratios for convenience and clarity in assisting in illustrating embodiments of the invention.
DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
The embodiment provides an embodiment of a control method and a system of the multi-mode system. As shown in fig. 1, the present embodiment includes:
step S101: setting the parameters of the second target area of the second mode system and the parameters of the initial target area of the first mode system to be the same parameter values.
The second target area is an image or a therapeutic target area of the second modality system, for example, when the second modality system is a medical image system, the second target area is an image range area of the second modality system, which is also referred to as a scan field of view (FOV) or a second scan field of view FOV2. The parameters of the second target area include position parameters, such as a center position parameter, a center line position parameter, a direction parameter, an angle parameter, a boundary parameter, a size parameter, and the like, and at least one of the parameters is copied as a parameter corresponding to the initial target area. Further, the copying is not limited to setting all parameters of the target area first, and then copying at least one parameter to other target areas, but may also set at least one parameter of at least two target areas to be the same value.
Optionally, the system of the second mode is a medical imaging system such as PET, CT, etc.; the system of the second mode is a medical image or treatment system such as MR, RT and the like.
In one embodiment, if the center position parameter of the second target area is (x, y), it is copied as the center position parameter of the initial target area, i.e., the center position parameter of the initial target area is set to (x, y). In another embodiment, the center line position parameter of the second target area is a, and then it is copied as the center line position parameter of the initial target area, that is, the center line position parameter of the initial target area is set to a. Alternatively, the user may directly copy the parameters of the corresponding second target area as the parameters of the initial target area, or the first modality medical image and/or the treatment system may automatically transmit the parameters of the corresponding second target area to the second modality medical image and/or the treatment system as the parameters of the initial target area. By adopting the mode to carry out the target area parameters, the operation is flexible, and the working efficiency of the medical imaging system and/or the treatment system can be improved.
Alternatively, the scanned object (scan site) may be pre-scanned by the second modality medical imaging system or the first modality medical imaging system to obtain a pre-scanned image (whole image). The pre-scan image is used as a positioning image of the scanned object.
Other imaging systems can be used to pre-scan the scanned object to obtain a pre-scanned image as a positioning image. The other imaging system may be a medical imaging system or an optical imaging system.
It should be noted that, the above-mentioned copying of the parameters of the second target area as the parameters of the initial target area may also be implemented by setting the parameters of the second target area and the initial target area to the same value at the same time, or by setting the parameters of the initial target area first and then copying them as the parameters of the second target area. Although the steps are different in sequence, the parameters of the second target area and the initial target area are consistent, and the steps are not different.
Step S102: and adjusting parameters of the initial target area to obtain a first target area of the first modal system.
And adjusting parameters of the initial target area to meet the image or treatment requirement of the first mode system. In one embodiment, the central position parameter of the initial target area is set as (x, y), and the initial target area is adjusted to obtain a new parameter (x 1 ,y 1 ). In another embodiment, the center line position parameter of the initial target area is set to be A, and the initial target area is adjusted to obtain a new parameter A 1 。
In one embodiment, the parameters of the initial target region are adjusted in accordance with the location parameters of the region of interest. If a doctor wants to perform a first-mode image or treatment on the liver of a medical object, parameters of an initial target area can be adjusted according to the information such as the position, the size and the like of the liver. In one embodiment, the location parameters of the region of interest may be determined based on a position slice, optical image, history parameters, etc. of the medical object.
Still further, in one embodiment, adjusting the initial target region parameters in accordance with the region of interest to obtain the first target region includes causing the first target region to entirely cover the region of interest. If a doctor wants to perform a first-mode image or treatment on the liver of a medical object, he wants to include the whole liver in the image or treatment target area, and therefore adjusts the initial target area parameters according to the information such as the position of the liver, so that the target area can completely cover the liver, and the target area parameters at this time are set as the parameters of the first target area.
Specifically, in one embodiment, the adjusting the first target area according to the region of interest to obtain that the first target area entirely covers the region of interest may include adjusting a center position parameter, a center line position parameter, a direction parameter, an angle parameter, a boundary parameter, a size parameter, and the like of the initial target area. In another embodiment, the central position parameter, the central line position parameter, the angle parameter, the boundary parameter, etc. of the region of interest are copied as the parameters corresponding to the first target region.
In another embodiment, the central position parameter of the second target area is (a, b), the angle parameter is 0, that is, the second target area is parallel to the direction of the bed, as shown in fig. 2 (a), the large square frame is the second target area, the black dot is the position corresponding to the central position parameter, the angle parameter is defined as the included angle between the target area and the bed, and the direction of the bed is shown by the arrow;
optionally, the information such as the size or the position angle of the region of interest (such as liver) is automatically determined according to the spatial position relation of the region of interest (such as liver) in (the whole) pre-scan image. Optionally, the scanning data acquired by the second modality medical imaging system can be fully utilized to obtain a larger-range pre-scanning image which can completely cover the region of interest, and more accurate and comprehensive parameter information such as the size, the position, the angle, the central line and the like of the region of interest can be acquired; and thus the initial target area parameters can be optimized. Furthermore, the second-mode medical imaging system is used for pre-scanning, and the first-mode medical imaging system is not required to be used for scanning, so that the use time of the first-mode medical imaging system is reduced, the use time of equipment is prolonged, the scanning time can be reduced, and the scanning efficiency is improved.
And copying the central position parameter and the angle parameter of the second target area to obtain the central position parameter and the angle parameter of the initial target area, and combining the preset size parameters (c, d) of the initial target area to obtain the boundary parameters (left boundary x=a-c/2, right boundary x=a+c/2, lower boundary y=b-d/2 and upper boundary y=b+d/2) of the initial target area, wherein the small box is the obtained initial target area as shown in fig. 2 (a).
The boundary parameters associated with the region of interest are (left boundary x=a 1 Right boundary x=b 1 Lower boundary y=c 1 Upper boundary y=d 1 ) Wherein a is 1 <b 1 ，c 1 <d 1 Found thatDue to b 1 >a+c/2, the initial target area does not cover the region of interest completely, so the boundary parameter of interest x=b can be replicated 1 As the corresponding initial target area parameter, the boundary parameter of the initial target area is obtained as (left boundary x=a-c/2, right boundary x=b) 1 Lower boundary y=b-d/2, upper boundary y=b+d/2). Fig. 2 (b) is a schematic diagram of an initial target area and a region of interest, fig. 2 (c) is a schematic diagram of adjusting the initial target area according to the region of interest, wherein a slash area is the region of interest, a point filling area is the initial target area, and a second target area is omitted.
As shown in fig. 2 (d), in one embodiment, the initial target area may be further adjusted to adjust the boundary parameters to (left boundary x=a-c/2, right boundary x=b) 1 +e, lower boundary y=b-d/2, upper boundary y=b+d/2), where e is a set positive number. In the imaging device, the image of the boundary of the target area may be deformed to a certain extent, so that a certain space is reserved between the boundary of the target area and the boundary of the region of interest, and the image of the edge of the region of interest can be prevented from being deformed, thereby providing an accurate image of the region of interest for a doctor.
And taking the adjusted parameters of the initial target area as parameters corresponding to the first target area to obtain the first target area.
The embodiment can finely adjust and position the target area of some images or treatment systems with smaller image or treatment range so as to ensure that the images or treatment can cover complete viscera or accurately aim at the region of interest of the required images or treatment.
Step S103: the first target area is used as an image or treatment target area of the first mode system.
Specifically, the first mode system uses the first target area as an image or a treatment target area, and the second mode system uses the second target area as an image or a treatment target area to perform single-bed medical image or treatment. Still further, the first modality system and the second modality system perform imaging and/or therapy simultaneously.
In the medical image or treatment field, the image or treatment target area is generally adjusted through the movement of the bed, one image or treatment target area corresponds to one bed, and in the multi-mode medical system, the multi-mode image and/or treatment target area corresponds to one bed, so that the multi-mode image and/or treatment can be synchronized, the consistency of the target areas is ensured, and the defect that one of the mode target areas cannot be adjusted is also brought. The embodiment is convenient for setting the target area by copying the target area parameters and adjusting the target area parameters and carrying out single bed image or treatment, and can also ensure that a certain mode target area can be flexibly adjusted and ensure the relative consistency of the target areas.
In another embodiment, the multi-modality medical system is a dual-modality medical imaging system, i.e. the first modality system and the second modality system are medical imaging systems. After the image scanning is performed in the above steps S101 to S103 to obtain image data, step S104 is further performed: and carrying out fusion display on the images acquired by the first modality system and the second modality system.
Examples
In this embodiment, it is desirable to perform some sort of image scanning or treatment of the heart of the region of interest of the medical subject, obtain images and/or perform treatment using two different modalities of medical imaging or treatment systems.
According to one embodiment of the present invention, a control system of a multi-modality medical imaging and/or therapy system further comprises: the target adjustment module and the scanning control module. The target adjusting module is used for copying parameters of a second target area of the second modal system to serve as parameters of an initial target area of the first modal system, and is also used for adjusting the parameters of the initial target area to obtain the first target area of the first modal system; the scanning control module is used for taking the first target area as an image or a treatment target area of the first mode system and taking the second target area as an image or a treatment area of the second mode system.
Specifically, the moving scan bed moves the medical object to a set scan region, and the region of interest of the medical object is the heart, which is irregularly shaped, as shown in fig. 3 (a).
In the prior art, when using a multi-mode imaging device to scan images, the fields of view of all multi-mode imaging systems, i.e., target areas, are all centered on a central line a, and as shown in fig. 3 (b), the target areas a and c are scanned at a position centered on the same bed central line, i.e., a straight line a. However, at this time, since the range of the target area c is small, the corresponding scanned image does not completely cover the region of interest.
In this embodiment, the target adjustment module sets the second target area of the second mode system as a, and the center line position of the second target area is shown as a line a in fig. 3 (a) -3 (d). In one embodiment, the second target area a may be set with the center line a aligned with the center of the region of interest, so as to ensure that the second target area a completely covers the region of interest.
In this embodiment, the target adjustment module is further configured to copy the center line position parameter of the second target area a of the second modality system as the center line position parameter of the initial target area c of the first modality system. In one embodiment, as shown in fig. 3 (b), the center line position parameter of the second target area a is copied as the center line position parameter of the initial target area c.
The target adjustment module is further configured to adjust a size parameter of the initial target area c according to the position size of the region of interest, so as to obtain a first target area b of the first mode, so that the first target area b completely covers the region of interest, as shown in fig. 3 (c) and fig. 3 (d).
According to an embodiment of the present invention, using the above-mentioned multi-modality medical imaging and/or therapy system, a control method of the multi-modality medical imaging and/or therapy system is provided, comprising the steps of:
s201: obtaining a localization image of the medical object;
The positioning image is an image and/or a shot image taken at the beginning of a scan for providing the doctor with positioning information of the medical object. The scout image may comprise a medical scan image, or may comprise an optical or other image.
A region of interest of the medical object is determined in the localization image. In one embodiment, the region of interest is the heart, as shown in FIG. 3 (a).
S202: moving the sickbed to move the medical object to a set image scanning and/or treatment area;
in particular, the patient bed is moved according to set bed parameters, such as moving the medical object to a scanning or treatment cavity, so that the region of interest scanning and/or treatment target area of the medical object is located within the scanning and/or treatment range of the system.
S203: setting a second target area of the second mode system as a;
specifically, the center line position parameter is set so that the center line thereof is aligned with the center of the heart of the region of interest, i.e., the straight line a in fig. 3 (a) and 3 (b). Still further, other parameters of the second target zone a are set such that the second target zone a completely covers the region of interest heart.
S201 to S203 are methods for setting the second target area of the second modality system.
S204: the second target zone parameters of the second modality system are copied as parameters of the initial target zone of the first modality system.
Specifically, the parameters include at least one of a target zone center position parameter, a center line position parameter, a direction parameter, and an angle parameter.
In one embodiment, the centerline position parameter of the second target area a is copied as the centerline position parameter of the initial target area. As shown in fig. 3 (b), the initial target area is c, and the central lines of the initial target area c and the second target area a are both straight lines a, that is, the central line position parameters are consistent.
In another embodiment, the center position parameter and the angle parameter of the second target area may be copied as the center position parameter and the angle parameter of the initial target area, as shown in fig. 3 (b), and the center position parameter and the angle parameter of the initial target area c and the second target area a coincide.
S205: and adjusting the initial target area c to obtain a first target area of the first modal system.
As shown in fig. 3 (b), the upper edge of the heart of the region of interest is truncated by the upper edge line of the initial target region c, so that the heart image obtained with the initial target region c as the target region is incomplete, and especially the image at the edge of the target region of the imaging system tends to be less accurate than the image at its center position. It is therefore necessary to change the target region so that it completely covers the region of interest heart.
Specifically, adjusting the initial target zone c includes adjusting at least one of a center position parameter, a center line position parameter, a direction parameter, an angle parameter, a boundary parameter, and a size parameter of the initial target zone c. Still further, the parameter for adjusting the initial target area c may be a corresponding parameter for directly copying the region of interest as the parameter of the initial target area c. The position parameter information of the locating plate and the interested region can be acquired in real time, and the parameters of the target region can be adjusted in real time.
In one embodiment, the size of the initial target area c is changed to expand the range of the target area c. Specifically, the size parameter of the initial target region c is adjusted to cover the heart region of the region of interest, resulting in a first target region, as shown in the first target region b in fig. 3 (b).
However, although enlarging the range of the target area may allow more image information to be obtained, often enlarging the size of the range increases the image scanning or treatment time. Therefore, the target region can also be made to completely cover the region of interest by changing other parameters of the target region, such as a center position parameter, a center line position parameter, an angle parameter, and the like.
In one embodiment, the centerline position parameter of the initial target region c is adjusted such that the centerline of the initial target region c is translated from the original centerline a to the new centerline a 'to cover the region of interest cardiac site to obtain a first target region, as shown in target region c' in fig. 3 (c).
In another embodiment, the centerline position parameter of the initial target region c is adjusted such that the centerline of the initial target region c is rotated from the original centerline a to a new centerline a 'to cover the region of interest cardiac site to obtain a first target region, as shown by the target region c' in fig. 3 (d).
In another embodiment, the angle parameter of the initial target zone c is adjusted such that the angle of the initial target zone c is rotated from a to a ', as shown by the target zone c' in fig. 3 (d).
Furthermore, an adjustment strategy can be preset in advance, and the initial target area is automatically adjusted according to the region of interest, so that a first target area is obtained.
In the above embodiment, the medical treatment or scanning is performed without changing the size of the target region, and the region of interest can be completely covered by using the minimum number of scanning layers, thereby saving the scanning time.
S206: taking a as a target area of the second modality system and c as a target area of the first modality system, and carrying out multi-modality medical image scanning and/or treatment on the medical object.
In particular, the multi-modal medical image scan of the medical subject is a single bed image scan and/or treatment. Further, in the image scanning and/or treatment process, according to a preset adjustment strategy, the initial target area is automatically adjusted according to the region of interest, so as to obtain a first target area which is used as a target area for real-time scanning and/or treatment. Still further, multi-modality medical image scanning and/or treatment of a medical subject is performed simultaneously to ensure synchronicity of image acquisition and/or treatment.
In one embodiment, the first modality system and the second modality system are both imaging systems, and step S207 may be performed after the first modality image and the second modality image are obtained in the above steps.
S207: and (3) fusing and displaying the first mode image and the second mode image obtained in the step S206.
The method and the device can be applied to the adjustment of the target area under the scene of simultaneous images and/or treatments of the multi-mode system so as to obtain the complete image of the region of interest, and avoid the need of carrying out supplementary images or treatments of a certain mode system after the simultaneous images and/or treatments of the multi-mode system are finished, thereby avoiding the possibility of mismatching caused by non-simultaneous images or treatments, and ensuring that the registration fusion of the obtained multi-mode images is more accurate for the multi-mode image system.
FIG. 4 shows another embodiment of a large-scale functional metabolism and molecular imaging diagnostic device for PET/MR systems, i.e. combined and integrated with positron emission computed tomography and MRI, with both PET and MR imaging functions.
For some images and/or treatments, the initial target area is obtained by copying the position parameters of the second target area, and the initial target area can be directly used as the first target area to perform multi-mode image or treatment. In general, the central line position parameter of the second target area of the PET modality system is directly copied and used as the central line position parameter of the first modality system, namely the first target area of the MR modality system; vice versa.
The second target area of the second modality system, i.e. the PET modality system, is larger, as shown by the solid color area of the figure. In this embodiment, the central line position parameter of the second target area of the PET modality system is duplicated, as shown by the central line of the PET bed in fig. 4, to obtain an initial target area, as shown by the dotted line box in the figure; and then, adjusting the initial target area according to the liver position of the region of interest to obtain a first target area, wherein the first target area is shown as a solid line square block in the figure.
Further, the adjustment of the initial target region according to the position of the region of interest may be to adjust the upper boundary of the initial target region according to the coordinates of the uppermost edge of the region of interest, i.e., the liver portion, and adjust the lower boundary of the initial target region according to the coordinates of the lowermost edge of the region of interest. The central line position parameter of the initial target area can be set and adjusted according to the central line position parameter of the region of interest.
In the whole body acquisition process, an MR protocol under a specific bed is added, the position and the setting of a target area of the added MR protocol are more flexible, the target area is adjusted according to the region of interest, and the integrity of an image is ensured, as shown in figure 4. Particularly in the localization of liver scans, the motion of the diaphragm muscle needs to be estimated according to the respiration of the medical object, and real-time and fine MR target area setting needs to be performed to ensure the integrity of the MR image of the liver.
Another embodiment applies equally to PET/MR systems.
In one application, as shown in fig. 5 (a), a fine scan of the nervous system is performed, wherein the second target region of the PET scanning system is shown as a solid-colored region, the angular parameter is 0, and the central position parameter is the position shown as a dot.
On the one hand, when the region of interest is the hippocampus, copying the central position parameter of the second target region of the PET scanning system as the initial target region position parameter, wherein the position is shown by a dot in the figure; and then adjusting the angle parameter to-15 degrees to obtain a first target area of the MR mode system, as shown by a dashed line frame.
On the other hand, when the region of interest is the whole brain, copying the central position parameter of the second target region of the PET scanning system as the initial target region position parameter, wherein the position is shown by a dot in the figure; and then adjusting the angle parameter to +15°, wherein the central position parameter is the position indicated by the square point, and expanding the range of the initial target area to obtain a first target area which completely covers the region of interest and is used as the first target area of the MR mode system, as shown in a solid line frame.
In another application, as shown in fig. 5 (b), a multi-planar scan of the heart is performed, wherein the second target region of the PET scanning system is shown as a solid-color region, the angular parameter is 0, and the central position parameter is the position shown as a dot.
Specifically, on the one hand, when the region of interest is the cardiac muscle, the angle parameter and the center position parameter of the second target region of the PET scanning system are duplicated to obtain an initial target region, as shown by a dashed frame in the figure, so that the scanning requirement of the cardiac muscle can be met, and the initial target region can be used as the target region of the MR scanning to perform the scanning, i.e. the prior art.
On the other hand, when the region of interest is located on the whole chest, the initial target region cannot cover the chest of the region of interest completely, scanning time is not wasted, and unnecessary scanning range is avoided, so that the scheme of the embodiment of the invention is adopted: copying an angle parameter and a central position parameter of a second target area of the PET scanning system to obtain an initial target area, wherein the initial target area is shown as a dotted line frame in the figure; and adjusting the central position parameter of the initial target area from a round point to a square point as shown in the figure, and simultaneously adjusting the size of the initial target area to completely cover the chest of the region of interest to obtain a second target area of MR scanning, wherein the second target area is shown as a square frame in the figure.
Examples
As shown in fig. 6, this embodiment is an effect comparison of the prior art and the technical solution of the present invention for the PET/MR device.
In the existing product, because the center of a target area of a multi-mode system is set in a correlated way, namely is consistent, when a scanning image obtained by a certain mode system is missing, the existing product can supplement an MR protocol which needs flexible positioning after PET acquisition is finished, however, the MR image is not acquired synchronously with PET at this time, and mismatching of MR and PET is easy to occur.
As shown in FIG. 6, with prior art non-simultaneous acquisition, i.e., acquisition of both PET and MR images with beds 1-5, it was found that the MR image could not completely display the entire region of interest, requiring an additional MR scan of bed 6. At this time, since the PET images of the beds 1 to 5 and the MR image of the bed 6 are not acquired synchronously, the deviation is large when the images are displayed in a fusion manner, and the workload and the working time are additionally increased.
If the technical scheme of the invention is adopted for synchronous acquisition, if the MR image of the bed 2 shoots the region of interest, the region of interest is fused with the PET images of the beds 1-5 for display, the defects of the prior art can be effectively overcome, the registration and fusion of the PET and MR images are more accurate, and the additional workload and the working time are avoided.

The selection can be manual selection or a scanning protocol template automatically selected by the system according to personal information of the scanned object, habits of users and preset preferences.
Step S302: the selected scanning protocol is displayed in a control-side display interface of the PET/MR system.
Specifically, the display information includes scan protocol parameters, and may also include a corresponding image of the scan protocol.
