Problems solved by technology

[0004] Due to the large number of FOV parameters involved in MRI scanning, the process of positioning through manual adjustment is cumbersome and time-consuming, which affects scanning efficiency and user experience
At present, the method of automatic setting of FOV parameters is mainly to determine the direction and size of FOV based on high-resolution 3D pre-scanning and image anatomical features. However, 3D pre-scanning takes a long time (50-60 seconds), which affects MRI. The positioning speed and efficiency of scanning restrict the application of this function

Abstract

The invention provides an FOV parameter setting method and device and an image processing device. The method comprises the steps of obtaining a plurality of positioning images obtained based on MRI scanning; determining a target positioning image from the plurality of positioning images through a pre-trained layer selection classifier, wherein the target positioning image is an image which meets apreset standard and has the highest probability; and generating an FOV parameter of the target positioning image through a pre-trained FOV parameter regression device. By applying the embodiment of the invention, automatic setting of the FOV parameters in the MRI scanning process is realized, compared with a manual adjustment method, the operation difficulty and complexity of an MRI system are reduced, the automatic positioning speed and efficiency are improved, and the user experience is further improved.

Description

technical field [0001] This specification relates to the field of medical imaging technology, and in particular to a method, device and image processing equipment for setting FOV (Filed of View, field of view) parameters. Background technique [0002] With the advancement of medical imaging technology, magnetic resonance imaging (Magnetic Resonance Imaging, MRI) is widely used clinically, and plays an increasingly important role in the diagnosis of diseases in various systems of the human body, especially for brain diseases and The diagnosis of neurological diseases plays an irreplaceable role. [0003] In MRI scanning, the FOV parameter is an important parameter for determining the scanning position and direction. The range of FOV needs to cover all the anatomical structures of the detection site, but also ensure that the spatial resolution will not be affected due to being too large, and the direction of FOV is also related to the accuracy of MRI diagnosis, so it is neces...
