Magnetic resonance imaging gating system, method and magnetic resonance imaging equipment

Abstract

The invention discloses a magnetic resonance imaging device and a gate control system and method of the magnetic resonance imaging device. The magnetic resonance imaging gate control system comprises a master control module, a spectrometer module, a gate control module and a monitoring module which is independent of the spectrometer module. The gate control module is used for generating a gate control mark according to acquired gate control data; the spectrometer module is used for triggering a data acquisition mark during data acquisition; the monitoring module is used for receiving and recording the gate control mark outputted by the gate control module, generation time of the gate control mark, the data acquisition mark and triggering time of the data acquisition mark, and further outputting the same to the master control module together; the spectrometer module is used for outputting image data to the master control module; and the master control module is used for synchronously corresponding the image data with the gate control mark according to the received gate control mark, the generation time of the gate control mark, the data acquisition mark and the triggering time of the data acquisition mark, and then re-arranging the image data and the gate control mark. The magnetic resonance imaging gate control system disclosed by the invention can realize gate control through the spectrometer module with lower real-time property.

Description

technical field [0001] The invention relates to a medical clinical imaging device, in particular to a magnetic resonance imaging device and its gate control system and method. Background technique [0002] Magnetic Resonance Imaging (MRI) is one of the main imaging methods in modern medical imaging. It is a kind of tomographic imaging, which has high resolution to soft tissue and no radiation damage to human body. The basic working principle of magnetic resonance imaging is to use magnetic resonance phenomena to obtain electromagnetic signals from the human body and reconstruct human body information. Magnetic resonance imaging mainly uses hydrogen protons in the human body. Hydrogen protons are divided into two energy levels under a static magnetic field. Under radio frequency excitation, hydrogen protons will transition from a low energy level to a high energy level. The high-energy level transitions back to the low-energy level, and radio frequency energy is emitted at ...
