Abstract

The embodiment of the invention provides a method and a device for acquiring coil information in a magnetic resonance system. According to the embodiment of the invention, a target recognition algorithm corresponding to the coil type of a target array coil is utilized to recognize a visible light image containing a subject and the target array coil to obtain first coil information of the target array coil, when the attitude information meets a set attitude, the position information in the first coil information is corrected according to the depth image of the subject to obtain the corrected first coil information, target coil information is acquired according to the corrected first coil information by using the mapping relation between the image coordinate system of the visible light image and the coordinate system of the magnetic resonance system, the coil information in the magnetic resonance system is automatically obtained through the depth image and the visible light image obtained before the subject enters a scanning cavity, manual intervention is not needed, the accuracy of the obtained coil information is improved, and the processing efficiency of the obtained coil information is improved.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a method and device for acquiring coil information in a magnetic resonance system. Background technique [0002] Magnetic Resonance Imaging (MRI) is one of the main imaging modalities in modern medical imaging. It has the advantages of high soft tissue resolution, no radiation damage, and diverse imaging parameters. It is widely used in clinical diagnosis. The basic working principle of magnetic resonance imaging is based on the phenomenon of magnetic resonance, using radio frequency pulses to excite hydrogen nuclei in the human body, and using gradient fields for spatial encoding, then using receiving coils to receive magnetic resonance signals, and finally using Fourier transform to reconstruct magnetic resonance image. [0003] Conventional magnetic resonance imaging uses multi-channel array coils for signal acquisition. The multi-channel array coil is compo...
