Embodiment 1

[0062] figure 1 It is a flow chart of a magnetic resonance scanning method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of automatically determining the scanning strategy of the shoulder joint. This method can be implemented by a magnetic resonance scanning device provided in the embodiment of the present invention. For execution, the device may be implemented in software and / or hardware. see figure 1 , the method specifically includes:

[0063] S110. Acquire a pre-scanned image of a region to be scanned of the scanned object.

[0064] In this embodiment, a pre-scan is performed on the to-be-scanned area of ​​the scanning object, and a pre-scanned image of the to-be-scanned area is obtained. Wherein, the pre-scanning refers to scanning the scanning object through a preset radio frequency sequence, and the preset radio frequency sequence is a radio frequency sequence for fast positioning and imaging of the scanning object,...

Embodiment 2

[0086] Figure 2A It is a flowchart of a magnetic resonance scanning method provided in Embodiment 2 of the present invention. On the basis of the above embodiments, a method for determining a scanning direction according to a pre-scan image is further provided. Accordingly, the method includes:

[0087] S210. Acquire a pre-scanned image of a region to be scanned of the scanned object.

[0088] S220. Perform image segmentation processing on the pre-scan image to acquire a humerus image of the shoulder joint.

[0089] S230. Determine the direction of the tendon in the region to be scanned according to the humerus image, wherein the direction of the tendon in the region to be scanned includes the direction of the tendon in the cross section and the coronal plane.

[0090] Wherein, the humerus image is pre-processed to determine the structural direction of each pixel in the humerus image, and the tendon direction is determined according to the structural direction of each pixel...

Embodiment 3

[0115] image 3 It is a magnetic resonance scanning method provided in the third embodiment of the present invention. On the basis of the above embodiments, a method for determining the scanning center according to the pre-scanning image is further provided. Accordingly, the method specifically includes:

[0116] S310. Acquire a pre-scanned image of an area to be scanned of the scanned object.

[0117] S320. Automatically or semi-automatically determine the scanning direction of the area to be scanned according to the pre-scanned image.

[0118] S330. Rotate the humerus image according to the scanning direction.

[0119] In this embodiment, when the scanning centers of different virtual planes are determined, the humerus image is rotated according to the scanning direction of the corresponding virtual plane. Exemplarily, if the scanning center of the cross section is determined, the humerus image is rotated according to the zero degree direction, the tendon direction of the...

Abstract

An embodiment of the invention discloses a magnetic resonance scanning method, a device and a system, wherein the method comprises the steps of acquiring a pre-scanning image of a to-be-scanned area of a scanning object; automatically or semi-automatically determining the scanning strategy of the to-be-scanned area according to the pre-scanning image and a preset rule, wherein the scanning strategy comprises a scanning center and a scanning direction; and performing magnetic resonance scanning on the to-be-scanned area according to the scanning strategy. The magnetic resonance scanning method, the device and the system provided by the embodiment settle problems of uncertain scanning center, uncertain scanning direction and low detecting precision caused by technician experience. The magnetic resonance scanning method, the device and the system have advantages of improving uniformity and accuracy of a scanning strategy to a pre-scanning area, and improving precision of a magnetic resonance scanning result.

Description

technical field [0001] Embodiments of the present invention relate to magnetic resonance technology, and in particular to a magnetic resonance scanning method, device and system. Background technique [0002] Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) is a technology that uses magnetic resonance phenomena for imaging. It has the characteristics of non-invasiveness, no ionization, and radiation. Advantages, especially for the soft tissue level display is very good, can greatly improve the diagnostic efficiency, often used in clinical diagnosis. [0003] Among them, the scanning imaging of shoulder joint diseases is a commonly used clinical application of magnetic resonance imaging technology. At present, the MRI scan of the shoulder joint is mainly based on the anatomical knowledge and the diagnosis experience of the shoulder joint, and the doctor manually determines the reference positioning line and the reference center for the scan detection image. The ...
