Magnetic resonance imaging apparatus
First Claim
1. A magnetic resonance imaging apparatus comprising:
- a first imaging unit configured to capture a plurality of first image data including a first reference frame and a second reference frame, the frames each including a reference position and a target region in an object;
a movement amount calculation unit configured to calculate a movement amount of a local position between the first reference frame and the second reference frame, the local position including the reference position and the target region;
a correction parameter setting unit configured to set a first correction parameter for correcting body motion of the object, based on the movement amount;
an error map generating unit configured to generate a predictive error map including a pixel value corresponding to a predictive correction error,wherein the predictive correction error is obtained from a predictive position and a predictive correction position, andwherein the predictive position is a position based on the movement amount and the predictive correction position is a position based on the first correction parameter; and
a display unit which displays the predictive error map and the first image data.

Abstract
According to one embodiment, a magnetic resonance imaging apparatus is provided. A first imaging unit captures a plurality of first image data including first and second reference frames. The frames include a reference position and a target region in an object. A movement amount calculation unit calculates a movement amount of a local position between the first and second reference frames. A correction parameter setting unit sets a first correction parameter for correcting body motion of the object, based on the movement amount. An error map generating unit generates a predictive error map including a pixel value corresponding to a predictive correction error. The predictive correction error is obtained from a predictive position based on the movement amount and a predictive correction position based on the first correction parameter. A display unit displays the predictive error map and the first image data.
