Cardiac Region Detection From Motion Analysis of Small Scale Reconstruction

摘要

A diagnostic imaging system ( 10 ) images overlapping cyclically moving and stationary regions of a subject. A low resolution reconstruction processor ( 50 ) reconstructs acquired data into a series of consecutive low resolution volumetric image representations. A motion region determining processor ( 70 ) determines a boundary of the moving region from the consecutive low resolution volumetric image representations. A high resolution reconstruction processor ( 60 ) reconstructs the acquired data into a high resolution volumetric image representation. A stationary region removing processor ( 84 ) removes stationary region image data from the high resolution volumetric image representation, which stationary region image data lies exterior to the moving region boundary. A display ( 86 ) displays the high resolution volumetric image representation.
