Abstract
Physiological medical image examinations consider as first step on the analysis how to track the same point of the patient body during some time; this procedure is named “Image Registration”. In this work, two approaches to define how identify same anatomical point to be follow in a series of patient images during a dynamic infrared images examination are presented allowing study temperature variation of each point. One of the, use never before considered methodology in the area: how tensor is transformed when there is coordinate modifications. This approach can be implemented in a semi-automatic method for image registration on Region of Interest (ROI) pre-processing without error when is possible to consider that the displacements of the volunteer are translation and rotation along the time of the examination. If there is other more generic motions the obtained point coordinates of the captured frames can de considered as a first step and additional correction is required for a perfect description of the bijective transformation of points along the examination time interval.
