Illuminating method and apparatus in nuclear magnetic resonance inspection

In an illuminating method for nuclear magnetic resonance inspection, the progress of inspection is visually informed to a patient so that the patient can easily and surely keep himself or herself at rest during a scanning period, thereby improving accuracy of the inspection and allowing the patient to feel more at ease. Control signals indicating the progress of inspection are supplied from a control circuit to an illumination control circuit. The illumination control circuit changes, based on the control signals, the intensity, color, etc. of light emitted from a magnet cavity illuminating panel in accordance with the progress of inspection. It is thus possible to visually inform the patient of the progress of inspection, improve accuracy of the inspection, and illuminate a magnetic field generating space for suppressing a feeling of uneasiness felt by the patient.

Magnetic resonance imaging method and apparatus for imaging a fluid portion in a body

Radio frequency pulses are repeatedly applied to a sample including a fluid portion positioned in a static magnetic field, so that spins of the sample are put into the steady-state free precession state so as to generate an FID signal just after the radio frequency pulse and generate a time-reversed FID signal just before the next radio frequency pulse. Both of the signals generated thus are detected and are subjected to image reconstruction process to image the fluid portion of the sample.

Method of producing nuclear magnetic resonance of an object and an apparatus therefor

A plurality of selective radio frequency π pulses are applied to an object placed in a static magnetic field which has a magnetic field gradient, to select a plurality of slices of the object corresponding to these pulses. Nuclear magnetic resonance signals are generated from the slices in a manner that a time interval between the selection of slice and the generation of nuclear magnetic resonance signal remains substantially constant for all of the slices.
