Abstract
An image data correcting device has a movement information acquiring section, a correcting section and a synthesizing section. The movement information acquiring section acquires movement information showing spatial distribution of the magnitude of a movement in the real space of an image pickup part of a detected body. The correcting section makes a correction different from that of a second area in a first area of image data collected by a scan of magnetic resonance imaging on the basis of the movement information. The synthesizing section synthesizes respective image data of the first area and the second area corrected by the correcting section.
Claims26
An image data correcting device comprising:
- a movement information acquiring section configured to acquire movement information showing a spatial distribution of the magnitude of a movement in real space of an imaged part of a detected body;
- a dividing section configured to divide image data which is spatially deteriorated by movement of the detected body into a plurality of spatial components in accordance with the magnitude of movement of the imaged part, using the acquired movement information;
- a correcting section configured to correct each of a plurality of k-space data sets respectively corresponding to each of the divided plurality of spatial components, by making a linear correction according to the magnitude of movement;
- a synthesizing section configured to synthesize, in k-space, the plurality of k-space data sets corrected by the correcting section;
- and
- a reconstruction section configured to reconstruct the synthesized k-space data into an image in real space.
