Title:
MAGNETIC RESONANCE IMAGING DEVICE
Document Type and Number:
Japanese Patent JPH06170
Kind Code:
A
Abstract:

PURPOSE: To dispense with intensification of an inclined magnetic field power source and to execute a high definition image pickup.

CONSTITUTION: The encode is divided into a center part and a peripheral part, and in the center part, control of an encode inclined magnetic field is executed by an application level, and in the peripheral part, its control is executed by an application time. A control means switching point for considering the influence exerted on image emphasis due to a variation of Te generated by this method is set. In such a way, there are such effects as a high definition image pickup is realized by a small inclined magnetic field power source capacity, a set range of an image pickup visual field is enlarged, the utilization efficiency of an inclined magnetic field power source is improved and Te can also be shortened, and a satisfactory picture quality can be provided.
