Title:
DEVICE AND METHOD FOR CREATING IN VIVO THREE-DIMENSIONAL MOVING IMAGE
Document Type and Number:
WIPO Patent Application WO/2010/008097
Kind Code:
A1
Abstract:
Provided is a device and method for creating an in-vivo three-dimensional moving image with a fewer amount of data than that required in conventional technology while ensuring an adequate processing speed. As data used to create three-dimensional time-series MR images, two-dimensional time-series MR images of slice planes (data slice) of an internal organ of the subject are captured at high speed, and two-dimensional time-series MR images of one or more slice planes (navigator slice) intersecting with the slice planes are captured at high speed. For each of the data slice images of slice planes, any data generally agreeing with time-varying data in the positions of the intersections with the navigator slice image is extracted. A three-dimensional time-series MR image is created by using the data slice images extracted from the data slice planes.
