Title: MEDICAL VIEWING SYSTEM HAVING MEANS FOR IMAGE ADJUSTMENT
Abstract:
A medical viewing system including an imaging means (2,3) and image data processing means (5) is arranged to facilitate production of different images of a feature of interest such that the pose of the feature of interest is comparable in the different images. The image data processing means (5) estimates the pose of the feature of interest in a second image relative to the pose thereof in a first image, typically generated at a different time, and applies an affine transformation, for example to the second image, so as to produce a transformed second image in which the feature of interest has substantially the same pose as in the first image. The image data may also be processed so as to normalize the intensity characteristics of the images to be compared. Gross differences in pose can be eliminated by processing the image data so as to generate control data indicating how to set up the imaging apparatus to produce an image having the feature of interest oriented substantially in a desired pose.
