METHOD AND ARRANGEMENT FOR ELECTROMAGNETIC RADIATION BASED NON-INVASIVE MONITORING OF A PERFORMANCE OF AN ANATOMIC OBJECT DURING AN OPERATION OR MEDICAL INTERVENTION
An arrangement for electromagnetic radiation based non-invasive monitoring of an anatomic object during an operation includes at least one imaging device for obtaining at least two or more images of at least one surface point on a surface of the anatomic object over at least one fraction of a characteristic movement cycle from the surface of the anatomic object. In addition the arrangement includes an output for a display device or the display device, and a control unit for determining deformation based on movements of the at least one surface point over the at least one fraction of the cycle between the at least two or more images of the surface of the heart in function of time. Further changes in the deformation is determined or determined deformation is compared to reference deformation values to find any deviation in the performance or state of the deformation determined.
