Signals and Systems

The Signals and Systems (SaS) group studies the processing of images and the recognition of patterns in them. The results show great promise for use in medical applications.

The group developed a system for measuring the constriction of blood vessels feeding the heart. Until recently, the accuracy of such measurements was influenced by the density of certain substances in the blood. Since the new method developed by SaS can correct the measured blood flow rates, this source of error is no longer applicable. SaS is particularly interested in what the measured data mean for the patient: does the constriction found really determine the blood supply to the heart muscle?

SaS also has years of experience in the development of computer systems that can generate 3D images of the body on the basis of differences in density (MRI) or in energy (CT). The current challenges are building memory into the system, achieving faster visualization and making this visualization interactive, and combining various imaging techniques in a single image.
