Artifact-reduced magnetic resonance tomography imaging calibrating method for medical application, involves determining device-specific time delay as slope of linear function between field of view displacements and phase values

摘要

The method involves specifying read-out direction and measuring phase values in a Fourier DC point for different field of view (FOV) displacements in the read-out direction. The device-specific time delay is determined as a slope of a linear function between the FOV displacements and phase values. The measuring and determining operations are repeated for variation of measurement parameter until a mathematical correlation is determined between the device-specific time delay and measurement parameter. Independent claims are included for the following: (1) artifact-reduced magnetic resonance tomography imaging measuring method; and (2) artifact-reduced magnetic resonance tomography imaging correction method.
