Alignment of multiple MR images using navigator signals |
摘要 |
A series of MR examinations of a patient are performed and the acquired images are aligned with each other so that small anatomic changes can be detected when images are compared. Alignment is achieved by acquiring navigator signals during each examination which are analyzed to measure patient misalignment from one examination to the next. The rotational and translational misalignment information is used to either prospectively or retrospectively align the MR images.
