HEAT EMISSION DISTRIBUTION INFORMATION GENERATION DEVICE AND METHOD, AND MAGNETIC RESONANCE IMAGING DEVICE AND PROGRAM

Title:

HEAT EMISSION DISTRIBUTION INFORMATION GENERATION DEVICE AND METHOD, AND MAGNETIC RESONANCE IMAGING DEVICE AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2013/147281

Kind Code:

A1

Abstract:

In an image generation device, an acquisition unit acquires a phase of a magnetic resonance signal which is emitted from a subject by applying a static magnetic field and a high-frequency magnetic field to a subject (step S102). A calculation unit calculates a degree of change of the acquired phase for a prescribed distance in a direction of the static magnetic field (step S103). A generation unit generates an image which represents a location distribution of a parameter which is dependent upon the calculated degree of change (step S106).
