Title:
MRT IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JP2005144173
Kind Code:
A
Abstract:

To improve the formation of an MRT (magnetic resonance tomography) image on the basis of a PPA (partially parallel acquisition) reconstituting method, even on both a motional artifact and imaging time.

This MRT image forming method is based on the partial parallel acquisition reconstituting method (the PPA reconstituting method). A plurality of partial data sets of a (k) space are made by a plurality of component coils. The whole of partial data sets forms a complete (k) space data set. Respective coil sensitivities of the respective component coils are determined on the basis of at least a part of the complete (k) space data sets. The respective partial data sets are converted into a position space by the PPA reconstituting method on the basis of the determined coil sensitivities. The converted partial data sets are superposed for providing an image data set having the little artifact.
