Title:
灌流測定のための動き補正
Document Type and Number:
Japanese Patent JP4666915
Kind Code:
B2
Abstract:
A CT scanner (10) for obtaining a medical diagnostic image of a subject includes a stationary gantry (12), and a rotating gantry (14) rotatably supported on the stationary gantry (12) for rotation about the subject. A plurality of temporally displaced volume images are gathered, divided into slices, and stored in slice memories (541, 542, . . . 54n). A slice comparitor (58) compares each slice to a selected reference slice. The slices are transformed by a slice transformer (60) to align the slices thereby correcting for movement of the subject over the scan period.
