Inspection apparatus using nuclear magnetic resonance

摘要

An inspection apparatus using nuclear magnetic resonance having arithmetic and control means for controlling a pulse sequence for detecting a nuclear magnetic resonance signal from a target to be inspected and calculating the detected signal. The arithmetic and control means controls an echo planar pulse sequence for acquiring a plurality of images of a predetermined same region of the target to be inspected; and arranges echo signal data obtained by measuring the inspection target by the echo planar pulse sequence and forms an EPI data set; designates a plurality of data points in k-space as observed points; designates a predetermined EPI data set to reference data for body motion for correcting influence by the body motion of the inspection target and calculates a reference phase as a phase of the body motion reference data at the observed points; calculates the phase of the EPI data set at the observed points; calculates a body motion correcting value expressing the influence by the body motion of the inspection target by using the phase difference between the phase of the EPI data set and the reference phase; and executes a process for eliminating the influence by the body motion of the inspection target by removing the phase difference of the EPI data set of the target to be inspected by using the body motion correction values.
