Method and system for capturing respiratory cycle in magnetic resonance scanning

Abstract

The embodiment of the invention provides a method and system for capturing a respiratory cycle in magnetic resonance scanning. According to the embodiment of the invention, when a designated respiratory capture protocol is scanned in the magnetic resonance protocol scanning process, prompting information is displayed on an interface, the captured respiratory cycle is prompted, whether the currentrespiratory cycle of a subject is in a stable state or not, it is determined that trigger conditions are met if the current respiratory cycle of the subject is in the stable state, trigger informationof the captured respiratory cycle is received, the respiratory cycle of the subject is captured according to the trigger information, a scanning operator can be reminded of trigger of the captured respiratory cycle in time and is prevented from forgetting to capture, it is ensured that image acquisition is located in a relatively stable area, re-scanning needed due to more artifacts in images andpoor quality is avoided, and accordingly the working efficiency is improved. The problem is solved to some degree that in the prior art, image quality is not qualified and re-scanning is needed due to the fact that trigger of the captured respiratory cycle is forgotten in the prior art and accordingly the working efficiency is low.

Description

【Technical field】 [0001] The solution relates to the technical field of communication, and in particular to a method and system for capturing respiratory cycles in magnetic resonance scanning. 【Background technique】 [0002] Magnetic resonance (Magnetic Resonance, MR) scanning is an important way to obtain medical images, and plays an important role in the medical field. [0003] Some parts of the human body are greatly affected by breathing movement, such as the chest cavity, pelvic cavity, abdomen and other parts. When using magnetic resonance equipment to scan these parts, when the trigger protocol (trigger protocol is the breath capture protocol) is scanned, it is necessary to capture the subject's respiratory cycle in order to guide the magnetic resonance system to acquire data at a relatively stable end-expiration period. Image data, the image collected in this way has less motion artifacts and better image quality. [0004] In the prior art, during the magnetic reso...
