AI Technical Summary

Technical Problem

In the existing magnetic resonance imaging technology, the excitation layer by layer leads to a long excitation time and poor image quality.

Method used

By determining the radio frequency parameters of each layer in the detection object, and synthesizing the target radio frequency parameter based on these parameters, the coil transmission channel transmits the target radio frequency signal to stimulate the layers in the film group at the same time.

Benefits of technology

The stimulus time is shortened, the quality of the image is improved, and the image quality of the image is reduced due to uneven launch field.
