Problems solved by technology

The present invention solves the disadvantages of the above-mentioned prior art graphical positioning method such as intuition and difficult operation, and proposes a three-dimensional graphical slice positioning method in magnetic resonance imaging, and innovatively introduces a three-dimensional positioning view into the magnetic resonance imaging system, It realizes information synchronous interaction with the two-dimensional positioning view and the parameter editor. By adjusting the positioning of the loaded pre-acquired two-dimensional reference view in the two-dimensional positioning view, it can be updated to the three-dimensional positioning view in real time so that the operator Able to quickly obtain the three-dimensional positioning of the slice

Embodiment 1

[0067] In this embodiment, the magnetic resonance imaging system of the present invention is used to perform three-dimensional graphic slice positioning, and the process is as follows Figure 4 shown.

[0068] Firstly, scan the two-dimensional positioning image of the detected target, and obtain two-dimensional reference images of one slice each in the coronal plane, sagittal plane, and transverse plane.

[0069] The target to be detected is, for example, a certain part of the patient, which is the part of interest of the tester, such as the brain. That is, when the examiner needs to know what lesion is in the patient's brain, he first scans the patient's brain with a two-dimensional positioning image, and obtains two-dimensional images of each slice of the coronal plane, sagittal plane, and transverse plane of the brain. Reference image. As shown in Figure 1, Figure 1(a) is the two-dimensional reference image of the coronal plane of the patient's brain, Figure 1(b) is the t...

Embodiment 2

[0083] In this embodiment, the positioning adjustment step is realized by the operator manipulating the slice graphical object in the three-dimensional positioning view, and other steps are similar to those in Embodiment 1.

[0084] The positioning process is as Figure 5 As shown in , the adjustment to the slice in the 3D positioning view is immediately updated to the 2D reference image in the 2D positioning view and displayed to the operator. At the same time, the adjustment to the slice in the 3D positioning view is the Changes to the positioning parameters are immediately updated in the parameter editor. The positioning parameters in the positioning protocol are synchronized between the 2D positioning view, the 3D positioning view and the parameter editor. Specifically, in the three-dimensional positioning view, the operator modifies the number of slices to 7, the thickness of the slices to 1 mm, the position of the slices to 2 mm away from the head, and the field of view...

Abstract

The invention belongs to the field of magnetic resonance imaging, and particularly relates to a three-dimensional graphical lamina positioning method in magnetic resonance imaging. The three-dimensional graphical lamina positioning method comprises the following steps of: loading a two-dimensional reference image to a two-dimensional positioning view and visualizing the two-dimensional reference image in a three-dimensional positioning view; then displaying a lamina graphical object on the two-dimensional and three-dimensional positioning views; and timely updating adjustment in the two-dimensional or three-dimensional positioning view to the three-dimensional or two-dimensional positioning view, wherein positioning reference variation caused by the adjustment is also timely reflected on a parameter editor. The invention also provides a magnetic resonance imaging system. According to the three-dimensional graphical lamina positioning method in the magnetic resonance imaging and the magnetic resonance imaging system thereof, the position and the direction of the three-dimensional graphical object can be intuitively displayed and operated, what you see is what you get, the lamina positioning step is simplified, the operation difficulty is reduced, and the study period is shortened.

Description

technical field [0001] The invention belongs to the field of magnetic resonance imaging, and in particular relates to a three-dimensional graphic slice positioning method in magnetic resonance imaging and a magnetic resonance imaging system. Background technique [0002] Graphical slice positioning is a graphical interface based on reference images, which can visualize and define (manipulate) graphical objects such as slice groups, thick slice groups, saturation regions, volume calibration regions, etc. A set of scan protocol parameters. The positioning of the slice group and the slab group determines the image position and direction of the scanned image, the saturation area is helpful for water-suppressed and fat-suppressed imaging, and the volume calibration area is helpful for obtaining a uniform image and spectral imaging. In the prior art, the reference image is generally a scanned positioning image or a series of images obtained in the same examination of the patient....
