  • Method of Motion Correction for Dynamic Volume Alignment Without Timing Restrictions
    Publication number: 20090116761
    Abstract: When performing repetitive scans of a patient using a magnetic resonance imaging machine or the like, patients often tend to move as they relax during a lengthy scanning session, causing movement in the volume or portion of the patient being scanned. A prospective motion correction component (64) accounts for patient movement by calculating transformation data representative of patient movement in multiple planes, as well as rotational movement, and a host (38, 122) evaluates the change in position relative to a most recent scanning geometry of the patient or dynamic volume. In this manner, correction or adjustment to the scanning geometry employed by an associated scanner (10) is made only for the differential between the current geometry and the most recent geometry, to mitigate redundant adjustment that can result in oscillatory over- and under-compensation during adjustments.
