Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a flowchart of a method for screening PET reconstruction data according to an embodiment of the present invention, where the embodiment is applicable to the case of screening reconstruction data, and is particularly applicable to the case of screening PET reconstruction data. The method may be performed by a screening apparatus of PET reconstruction data, which may be implemented in hardware and/or software, which may be integrated in a device (e.g. a PET device), comprising in particular the steps of:
Wherein the data screening reference signal comprises at least a count rate signal and at least one physiological motion signal.
Illustratively, the execution device of the embodiments of the present invention may be a PET device.
The original scan data may be PET scan data, obtained by scanning with a PET device, for PET image reconstruction.
Wherein the data screening reference signal may be used to determine a target reconstructed data range of the original scan data. The target reconstruction data range may be a data range for subsequent reconstruction.
The count rate signal is an important indicator of PET reconstruction data. The user can screen the PET reconstruction data by referring to the count value change condition.
Illustratively, the physiological motion signal may include: electrocardiosignals, respiratory signals, motion signals, and the like.
After the motion signal is accessed to the camera through the PET machine, the PET machine receives the video signal, automatically recognizes a preset position (such as a leg position and the like), analyzes the motion condition of the position, and draws a motion curve which changes along with time.
Signals of electrocardios, respiration, etc. may be acquired by a VSM (Vital Signs Monitor, sign signal detector) device or by some wearable device.
The data filtering reference signal and the original scan data may be stored in a unified standard format. The unified standard format may be a signal with time as abscissa and amplitude as ordinate. The data filtering reference signal and the original scan data first need to be subjected to a uniform time stamping operation before being used for processing, so that subsequent processing is performed.
Optionally, the data filtering reference signal is not limited to an electrocardiosignal, a respiratory signal, a motion signal and a counting rate signal, and the embodiment of the invention provides a data interface, and signals except the electrocardiosignal, the respiratory signal, the motion signal and the counting rate signal can be added, and when the signals except the electrocardiosignal, the respiratory signal, the motion signal and the counting rate signal are added, the signals can be processed by converting the signals into the form of the unified standard format. Meanwhile, one, two or more data screening reference signals can be reduced according to the actual demands of users. For example, if there are currently electrocardiographic signals, respiratory signals, motion signals, count rate signals, one or more of these data filtering reference signals may be removed from the second display interface, such as removing motion signals, as desired.
Optionally, reducing one, two or more data screening reference signals comprises: dragging the data screening reference signals to be reduced out of the current display area to delete the data screening reference signals to be reduced; or receiving a selection operation of the data screening reference signal to be reduced, which is input by a user, triggering a deletion button to delete the data screening reference signal to be reduced, and the like. It should be noted that, one data filtering reference signal may be reduced at a time, or two or more data filtering reference signals may be reduced simultaneously. In addition, the operation of reducing the data filtering reference signals may be performed simultaneously with each simultaneous selection of two or more data filtering reference signals to be reduced.
The preset interactive interface can be used for displaying the data screening reference signal and comprises a first display area and a second display area. The first display area is used for displaying all the data screening reference signals, and when a new data screening reference signal is accessed, the first display area can also be displayed in real time. The second display area can display the data screening reference signals selected by the user from the first display area, can display the default data screening reference signals of the system, and can also display the data screening reference signals selected by the user last time. The plurality of data filtering reference signals may be sequentially displayed in the second display area according to the user's setting. Each data-screening reference signal may be displayed up and down in turn, such that each data-screening reference signal is displayed separately, and the axes of each data-screening reference signal time are aligned at the start.
Optionally, receiving a selection operation input by a user in the first display area, and displaying at least one data screening reference signal corresponding to the selection operation in the first display area in a second display area of the preset interactive interface.
The first display area contains all data screening reference signals, a user can select the required data screening reference signals according to the requirement, a selection operation is input in the first display area, and when the selection operation input in the first display area by the user is received, the selected data screening reference signals can be displayed in a second display area of the preset interactive interface.
Optionally, the receiving a selection operation input by the user in the first display area includes:
receiving operation of dragging at least one data screening reference signal in the first display area to the second display area by a user; or, receiving an operation that a user drags at least one data screening reference signal in the first display area to the second display area; or receiving a click operation of the user on at least one data screening reference signal in the first display area, wherein the click operation comprises single click or two or more continuous clicks and the like.
The operation of receiving the selection input by the user in the first display area may be an operation of selecting one set of data filtering reference signals, or an operation of simultaneously selecting two or more sets of data filtering reference signals. Displaying at least one data screening reference signal in the first display area in a second display area of the preset interactive interface comprises displaying one, two or more data screening reference signals corresponding to selected operations in the second display area of the preset interactive interface. Further, one of the data filtering reference signals may be selected, and two or more data filtering reference signals corresponding to the selected operation may be displayed in the second display area of the preset interactive interface. For example, an association relationship may be further established between at least two data filtering reference signals, and when one of the data filtering reference signals is selected, an associated data filtering reference signal with the selected data filtering reference signal is obtained according to the association relationship, so that the selected data filtering reference signal and the associated data filtering reference signal are displayed in the second display area of the preset interactive interface.
Optionally, a display position adjustment operation of the user in the second display area is received, and the at least one data filtering reference signal is adjusted according to the display position adjustment operation, where the display position adjustment operation includes selecting and dragging the at least one data filtering reference signal. For example, when the user selects the count rate signal, the respiration signal, and the motion signal in the first display area, the count rate signal, the respiration signal, and the motion signal may be dragged into the second display area, respectively, and the second display area sequentially displays the curves of the count rate signal, the respiration signal, and the motion signal from top to bottom according to the dragging sequence of the user.
The user may further drag the adjustment in order of the count rate signal, the respiration signal, and the motion signal. For example, when the user wants to move the count rate signal to the relatively lowest of the curves of the count rate signal, the respiratory signal, and the motion signal, the count rate signal may be selected and dragged down the curve of the count rate signal to the lower of the curve of the respiratory signal and the motion signal.
And step 103, determining a target reconstruction data range according to at least one data screening reference signal in the second display area, and screening out target reconstruction data in the original scan data according to the target reconstruction data range.
For example, assuming that the data filtering reference signal in step 102 includes a motion signal, the filtering process is to collect video image signals of a predetermined portion of the patient through a camera of the PET device according to a preset frequency, calculate the motion amplitude of the patient by comparing the change condition of images before and after the portion, normalize the motion amplitude, and use a data range lower than the motion amplitude threshold as a reconstructed data range of the motion signal according to the motion amplitude threshold.
In step 102, if the data screening reference signal includes an electrocardiograph signal, the screening process automatically identifies the position of the R wave according to the acquired electrocardiograph signal and sets a range below the electrocardiograph signal threshold, that is, a data range of the heart in a resting phase in the cardiac cycle, as a reconstructed data range corresponding to the electrocardiograph signal.
Assuming that the data screening reference signal in step 102 includes a respiratory signal, the screening process identifies a peak and a trough of a waveform according to the acquired respiratory signal, and recommends a data segment with smaller relative respiratory motion between the peak and the trough as a reconstructed data range corresponding to the respiratory signal according to a set respiratory signal threshold.
For count rate signals, the screening process is as follows: and comparing the acquired count rate signal with a preset count rate threshold value, and recommending the data segment exceeding the threshold value as a reconstruction data range corresponding to the count rate signal.
The reconstruction data range recommended by each signal is marked on a corresponding signal curve in a second display area of the preset interactive interface, for example, a rectangular frame or two vertical lines with preset colors can be adopted to mark the reconstruction data range.
Optionally, the determining the target reconstruction data range according to at least one of the data filtering reference signals in the second display area includes:
if at least two data screening reference signals exist in the second display area, determining a reconstruction data range corresponding to each data screening reference signal according to each data screening reference signal and a preset signal threshold corresponding to the data screening reference signal;
and determining a common data range among all the reconstruction data ranges according to the time information in each data screening reference signal, and taking the common data range as a target reconstruction data range.
Specifically, when two or more data filtering reference signals exist in the second display area of the preset interactive interface, determining a reconstruction data range corresponding to each data filtering reference signal according to each data filtering reference signal and a preset signal threshold corresponding to the data filtering reference signal, and then taking an intersection of reconstruction data ranges recommended by the two or more data filtering reference signals, namely, a common data range (intersection) of respective time periods corresponding to the data filtering reference signals, as a target reconstruction data range, screening out target reconstruction data in the original scan data according to the target reconstruction data range, and reconstructing a PET image according to the target reconstruction data. If the reconstructed data range recommended by each of the two or more data screening reference signals does not have intersection, directly displaying the reconstructed data range corresponding to each data screening reference signal determined according to each data screening reference signal and a preset signal threshold corresponding to the data screening reference signal.
It will be appreciated that the target reconstruction data range and the reconstruction data range recommended by the reference signal according to the various data screening may be one or more, and the number is not limited.
According to the technical scheme, the original scanning data and at least two data screening reference signals are obtained, wherein the data screening reference signals at least comprise a counting rate signal and at least one physiological motion signal, so that a user can adjust the input data screening reference signals according to requirements, and the data screening reference signals have good interactivity. And displaying the at least two data screening reference signals in a first display area of a preset interactive interface, and displaying at least one data screening reference signal in the first display area in a second display area of the preset interactive interface, so that the display of the preset interactive interface is more visual. Furthermore, a target reconstruction data range is determined according to at least one data screening reference signal in the second display area, and target reconstruction data in the original scan data is screened out according to the target reconstruction data range, so that reconstruction can be performed on the original scan data more accurately. The technical scheme solves the problems that each index cannot be synthesized due to the adoption of the single-dimension data screening reference signal, and further the reconstructed image with higher quality cannot be obtained, and the user-executable operation is limited, so that the screening mode based on the multi-dimension data screening reference signal is realized, the obtained PET reconstructed data is more accurate, the reference is provided for the user, the data screening reference signal can be conveniently switched, the real-time performance and the interactivity are good, and the clinical working efficiency is improved.
