The invention provides a propeller magnetic resonance imaging reconstruction system and method. The method comprises the following steps: step A1, acquiring an accelerated magnetic resonance image to be reconstructed and a corresponding coil sensitivity image; inputting an accelerated magnetic resonance image to be reconstructed and a coil sensitivity image into the trained deep learning model to output leaf images and motion parameters between the leaf images; correcting each leaf image based on the output motion parameters; and combining each corrected leaf image to obtain a reconstructed high-resolution de-artifact magnetic resonance image. The accelerated propeller image is processed, the generated magnetic resonance image is better in quality, high in signal-to-noise ratio and few in artifacts, and diagnosis of a doctor is facilitated, and the accuracy is improved.
Description
technical field [0001] The present invention relates to the technical field of medical image processing, in particular to a reconstruction system and method for propeller magnetic resonance imaging. Background technique [0002] An important problem with magnetic resonance imaging (MRI) is that the patient may move uncontrollably during the scan, which can cause blurring and artifacts in the image. One solution to this problem is to use propeller scanning technology for motion correction, also known as propeller scanning. In the Propeller method, the data is divided into multiple blade parts called blade parts during K-space acquisition. In each blade, it is similar to the traditional Cartesian scanning method, using a fixed phase encoding direction to collect a resolution The lower image, while the direction of the phase encoding between the different blades is rotated by a certain angle (eg figure 1 As shown), since each blade will collect the image of the central area o...
