Patent ID: 7616981

Claim:
An inspection apparatus using nuclear magnetic resonance comprising: a controller for controlling a pulse sequence which applies a radiofrequency magnetic field and a magnetic field gradient to a living body placed in a static magnetic field to detect a nuclear magnetic resonance signal produced from said living body; and an arithmetic processor for performing an image reconstruction of an imaging section using said detected nuclear magnetic resonance signal, wherein said controller is configured to: (1) control application of a first pulse sequence detecting said nuclear magnetic resonance signal when said living body stops exhalation or inhalation; (2) control application of said first pulse sequence once in a state that said living body breathes; and (3) control of repeated application of a second different pulse sequence for detecting said nuclear magnetic resonance signal at predetermined repetition time intervals, wherein said arithmetic processor is configured to: (a) perform arithmetic processing of acquiring a reference projection of said imaging section from said nuclear magnetic resonance signal detected in said first pulse sequence when said living body stops exhalation or inhalation; (b) perform arithmetic processing of acquiring a projection of said imaging section from said nuclear magnetic resonance signal detected in said first pulse sequence when said living body breathes; and (c) perform arithmetic processing of determining a similarity coefficient between said projection and said reference projection, said similarity coefficient being scalar, wherein said controller is further configured to (4) collect or discard said nuclear magnetic resonance signals from said second pulse sequence based on said similarity coefficient, and reconstructing said image using the collected nuclear magnetic resonance signals, and wherein said projection is one-dimensional, and said reference projection is one-dimensional.
