Problems solved by technology

As a result, image pixels deviate from their true positions, resulting in noticeable geometric distortion
[0004] Currently, View Angle Tilting (VAT) is used to solve the problem of geometric distortion of MRI images
However, although the geometric distortion can be effectively calibrated by using the angle of view tilt method, the final image of the angle of view tilt method will appear blurred. will not serve as a basis for diagnosis

Abstract

The invention discloses a metal implant magnetic resonance imaging method and system, a terminal and a storage medium. The method is applied to an ultra-low field magnetic resonance imaging device, and is characterized by comprising the following steps: acquiring safety scanning parameters according to the information of a metal implant; setting radio frequency parameters and imaging parameters of the ultra-low field magnetic resonance imaging device according to the safety scanning information; and carrying out magnetic resonance imaging according to the radio frequency parameters and the imaging parameters. The magnetic resonance imaging device with an ultra-low field can be applied to magnetic resonance imaging of the metal implant, and the obtained image is clear and cannot be affected by the high inherent magnetic susceptibility of the metal implant.

Description

technical field [0001] The invention relates to the field of nuclear magnetic resonance, in particular to a metal implant magnetic resonance imaging method, system, terminal and storage medium. Background technique [0002] With the development of medical technology, Magnetic Resonance Imaging (MRI) technology is becoming more and more important. Magnetic resonance imaging is a routine procedure for diagnosing and treating various diseases and injuries. It can accurately reflect the pathological tissue conditions, enable doctors to make accurate diagnoses, and provide targeted treatment to patients based on the results of magnetic resonance imaging. [0003] When a person or thing has metal implants inside, it can affect the accuracy of magnetic resonance imaging. Due to the high intrinsic magnetic susceptibility of metal implants, they interfere with the local magnetic field, causing a change in the resonant frequency. As a result, image pixels deviate from their true pos...
