Abstract

The invention belongs to the technical field of medical magnetic resonance scanning control and provides a magnetic resonance scanning trigger device, and a system and method for magnetic resonance scanning control. According to the invention, the magnetic resonance scanning trigger device composed of a trigger module, a detection module and a transmission module is adopted, so that when a user gets ready for holding breath, the trigger module will start a corresponding state change according to the user's trigger operation; the detection module detects a state of the trigger module and generates corresponding instruction information when the trigger module starts the state change; information amplifying processing is conducted to the instruction information; and the transmission module receives the instruction information treated by the amplifying processing, converts the amplified instruction information into a corresponding digital signal and sends the signal to a magnetic resonance scanning control device. In this way, the magnetic resonance scanning control device can control the magnetic resonance scanning device to start scanning the user according to the digital signal. The user can autonomously select the time for scanning start, so that image artifacts caused when the user is not well-prepared can be avoided.

Description

technical field [0001] The invention belongs to the technical field of medical magnetic resonance scanning control, and in particular relates to a magnetic resonance scanning trigger device and a magnetic resonance scanning control system and method. Background technique [0002] Magnetic resonance imaging (Magnetic resonance imaging, MRI), as an effective diagnostic imaging method, has been widely used in clinical applications. When a lesion occurs somewhere in the human body, there will be differences in the proton density and other characteristics between normal tissue and lesion tissue, and magnetic resonance scanning can detect the existence of these differences very well and quantify them. However, MRI scanning also has its disadvantages: the scanning time is long, and artifacts are easily affected by motion, especially in abdominal tissue and organ scans. [0003] At present, when the abdominal breath-hold scan is performed by magnetic resonance, the existing technol...
