Abstract

The invention relates to a magnetic resonance system and a positioning method used for the same. The positioning method comprises the following steps: acquiring the image of the whole body of an imaging object on a supporting table by a second radiofrequency coil; recognizing a target region corresponding to a to-be-scanned portion in the image of the whole body; acquiring the relative position information of the target region on the supporting table; and moving the to-be-scanned portion to a magnet center of the magnetic resonance system according to the relative position information. According to the positioning method used for the same, the image of the whole body is acquired, the corresponding region of the to-be-scanned portion is recognized, then, automatic positioning is realized, the magnetic resonance system is simple and convenient to operate, and possible injury to a patient due to positioning through a laser lamp is avoided.

Description

technical field [0001] The invention relates to the field of magnetic resonance, in particular to a positioning method for a magnetic resonance system and a magnetic resonance system. Background technique [0002] Magnetic resonance imaging (magnetic resonance imaging, referred to as MRI) is a biological magnetic spin imaging technology, that is, in an external magnetic field, based on the characteristics of the spin motion of the atomic nucleus, the detector is used to detect the imaging object produced by radio frequency pulse impulse The signal is processed and converted, and the image generated after the processing and conversion is displayed on the monitor. [0003] In a traditional MRI system, a laser light is used for positioning. After the patient and the coil are in place, the bed is raised and moved under the laser light. After the patient closes their eyes, the laser light is turned on, and the bed is fine-tuned so that the center of the coil is completely aligned...
