Magnetic resonance imaging acquisition system and magnetic resonance imaging acquisition method

Abstract

The invention provides a magnetic resonance imaging collecting system which comprises a signal collecting device and a feedback device, wherein the collecting device is used for sequentially collecting thoracic diaphragm position signals of a exhale and inhale view of a patient, the feedback device includes a display screen, and the thoracic diaphragm position signals are fed back to the patient in real time through the display screen. The invention also provides a magnetic resonance imaging collecting method. The magnetic resonance imaging collecting system and magnetic resonance imaging collecting method aim at improving efficiency of magnetic resonance breath state collecting, reducing the influence of the breath state on imaging quality, and simultaneously achieving low time consumption.

Description

technical field [0001] The invention relates to an imaging system and an imaging method, in particular to a magnetic resonance imaging acquisition system and a magnetic resonance imaging acquisition method. Background technique [0002] In traditional magnetic resonance imaging systems, respiratory navigation echo technology is applied to monitor the movement of the patient's diaphragm in real time, reducing artifacts and image distortion caused by respiratory movement, so as to achieve better imaging of the lesion. In the traditional navigation echo technology, the navigation bar monitors the position of the diaphragm, and the signal is collected only when the position of the diaphragm falls within the allowable range. When the patient is breathing evenly, the image has no respiratory motion artifacts, and the continuity is good. The quality of the original image and 3D reconstruction image is good, and the lesion is clearly displayed; when the patient's breathing is uneven...

Problems solved by technology

In the traditional navigation echo technology, the navigation bar monitors the position of the diaphragm, and the signal is collected only when the position of the diaphragm falls within the allowable range. When the patient is breathing evenly, the image has no breathing motion artifacts, and the continuity is good. The quality of the original image and 3D reconstructed image is good, and the lesion is clearly displayed; when the patient's breathing is uneven, the scanning time needs to be extended, and artifacts often appear in the image

Therefore, the respiratory navigation system has the disadvantages of long scanning time and low image quality
