Title:
MAGNETIC RESONANCE IMAGING APPARATUS
Document Type and Number:
Japanese Patent JP2019047978
Kind Code:
A
Abstract:
To provide a magnetic resonance imaging apparatus highly accurately calculating local phase distribution of an entire brain including a brain surface area.SOLUTION: The magnetic resonance imaging apparatus includes: a static magnetic field generation magnet for generating a static magnetic field in a space where a subject is disposed; a transmission unit for transmitting a high-frequency magnetic field to the subject; a reception unit for receiving a nuclear magnetic resonance signal generated from the subject by the transmission of the high-frequency magnetic field; a gradient magnetic field application unit that applies a gradient magnetic field for adding position information, to the nuclear magnetic resonance signal; a computer that controls the transmission unit, the reception unit, and the gradient magnetic field application unit and performs arithmetic processing to the nuclear magnetic resonance signal; and a display unit for displaying an image arithmetically processed by the computer. The computer performs prescribed arithmetic processing.SELECTED DRAWING: Figure 3
