Image acquisition method of magnetic resonance scanner and device thereof, equipment and medium

Abstract

The invention relates to an image acquisition method and a device of a magnetic resonance scanner, equipment and a medium. The method comprises the following steps: collecting vital sign data in realtime; inputting the vital sign data into a neural network which is completely trained; determining whether the completely trained neural network outputs a gating trigger signal or not, wherein the gating trigger signal is predicted by the completely trained neural network according to the vital sign data; and controlling the magnetic resonance scanner to perform image acquisition under the condition of judging that the completely trained neural network outputs the gating trigger signal. According to the invention, the method solves a problem that the quality of an image collected through gating triggering becomes poor because of gating false triggering in a gating collection technology based on real-time R-wave detection in the related technologies, and improves the quality of the collected image.

Description

technical field [0001] The invention relates to the field of medical equipment control, in particular to an image acquisition method, device, equipment and computer-readable storage medium of a magnetic resonance scanner. Background technique [0002] Magnetic Resonance (MR for short) and Positron Emission Tomography (PET for short) / MR thoracic and abdominal scans are often limited by respiratory motion and heartbeat. Heart beating and respiratory movement will cause a large loss of magnetic resonance signals and affect image quality. [0003] In order to reduce the impact of respiration and heartbeat on image quality, gating acquisition technologies are widely used in related technologies, for example, ECG trigger gating, pulse trigger gating, and respiration trigger gating. The imaging technology adopts the gated acquisition technology to monitor the vital sign signals of breathing and heartbeat in real time, and generates a gated acquisition signal when a specific vital ...
