AI Technical Summary

Technical Problem

In magnetic resonance imaging (MRI), misalignment of image sequences under different scanning methods leads to inaccurate image analysis results and a lack of mutual reference value.

Method used

By acquiring the reference scan sequence and the scan protocol to be executed for the target region, the scan parameters are adjusted to generate the target scan sequence, so that the position of the excitation layer under different scan modes is aligned with the excitation layer of the reference scan sequence, and the shimming range of the reference scan sequence is reused.

Benefits of technology

It improves the accuracy and reference value of medical image analysis results under different scanning methods, saves imaging time, and improves imaging efficiency.

Abstract

The application relates to a scanning parameter setting method and device and a magnetic resonance scanning method. The method comprises the following steps: a computer device acquires a reference scanning sequence corresponding to a target part, determines a first scanning range of an excited slice layer of the target part according to the reference scanning sequence, acquires a to-be-executed scanning protocol, determines a second scanning range of a to-be-excited slice layer of the target part according to the to-be-executed scanning protocol, adjusts a scanning parameter of the to-be-executed scanning protocol in the case that the second scanning range is different from the first scanning range, and generates a target scanning sequence. In the method, the computer device generates at least one target scanning sequence in which a to-be-excited slice layer is aligned with an excited slice layer determined by the reference scanning sequence based on the first scanning range and the second scanning range of the reference scanning sequence. In this case, the scanning parameter of the to-be-executed scanning protocol can reuse the scanning parameter of the reference scanning sequence, and the accuracy of a medical image analysis result of the target part is improved.
