Abstract

The embodiment of the invention discloses a radial golden angle magnetic resonance heart film imaging method and device and equipment. The method comprises the steps of obtaining magnetic resonance K-space data sampled by a radial golden angle with a preset channel number of a target object; performing re-arranging on the K-space data to obtain preset frame number undersampled K-space data; inputting the preset frame number of undersampled K-space data to a cross region image rebuilding network to obtain a target image. According to the embodiment, the problem that long time is consumed in theimage rebuilding process on the basis of the radial golden angle sampled data is solved; the purpose of shortening the image rebuilding time of heart magnetic resonance data sampled by the radial golden angle can be achieved, and the quality of a rebuilt image is improved.

Description

technical field [0001] Embodiments of the present invention relate to medical imaging technology, in particular to a radial golden angle magnetic resonance cardiac cine imaging method, device and equipment. Background technique [0002] Magnetic resonance cardiac cine imaging is a non-invasive imaging technique that can be used to evaluate cardiac function, abnormal ventricular wall motion, etc., and provide rich information for clinical diagnosis of the heart. However, due to the constraints of magnetic resonance physics and hardware, and the length of the cardiac motion cycle, magnetic resonance cardiac cine imaging is often limited in time and space resolution, and cannot accurately evaluate the cardiac function of some heart diseases, such as arrhythmia. Therefore, on the premise of ensuring the imaging quality, it is very important to use fast imaging methods to improve the temporal and spatial resolution of magnetic resonance cardiac cine imaging. [0003] At present,...
