Medical imaging at two temporal resolutions for tumor treatment planning
First Claim
Patent Images
1. A method of medical imaging comprising:
- (a) obtaining at a first temporal resolution a first medical image of a region of interest of a patient;
(b) obtaining at a second temporal resolution a second medical image of the region of interest, said second temporal resolution being lower than the first temporal resolution;
(c) registering the first and second medical images with one another such that common reference points in the first and second medical images coincide; and
, (d) superimposing the first and second medical images over one another.

Abstract
A method of medical imaging includes obtaining at a first temporal resolution a first medical image 100 of a region of interest of a patient, and obtaining at a second temporal resolution a second medical image 200 of the region of interest. The second temporal resolution is lower than the first temporal resolution. The method also includes registering the first and second medical images with one another such that common reference points in the first and second medical images coincide. Finally, the first and second medical images are superimposed over one another.
