Title:
MAGNETIC RESONANCE IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/199997
Kind Code:
A1
Abstract:
An MRI system according to an embodiment is provided with an MRI sequence controller (30) and an MRI system controller (22). The MRI sequence controller (30) performs a prescan to collect sensitivity distribution of a coil as a prescanning unit. The MRI sequence controller (30) performs a main scan to collect signals of a magnetic resonance image as a main scanning unit. The MRI system controller (22) corrects the sensitivity distribution on the basis of distortion in the magnetic resonance image due to performance of the main scan as a correction unit. The MRI system controller (22) uses the corrected sensitivity distribution to generate an output magnetic resonance image as a generation unit.
