Abstract:
1. A system for piecewise registration, comprising: a tangible memory device for storing a program; and a processor in communication with the memory device, the processor operative with the program to: acquire a first image dataset at a first time and a second image dataset at a second time, wherein the first and second image datasets each comprise same patient anatomy; receive a selection of the first and second image datasets, perform a first registration the first and second image datasets with each other; display the registered first and second image datasets; receive an input defining a sub-volume around an anatomical structure in the first image dataset that is not properly aligned with a corresponding anatomical structure in the displayed second image dataset; and align the anatomical structure in the first image dataset with the corresponding anatomical structure in the second image dataset by performing a second registration by registering the sub-volume with a whole-body volume of the second image dataset.
