DEVELOPMENT OF A DYNAMIC TEST PHANTOM FOR OPTICAL TOPOGRAPHY

Optical topography (OT) is a near infrared spectroscopy (NIRS) technique that provides spatial maps of haemodynamic and oxygenation changes. When developing, testing and calibrating OT systems it is often necessary to use tissue simulating phantoms that are capable of providing realistic changes in attenuation properties. We present a novel dynamic tissue phantom that enables spatially and temporally varying tissue properties to be reproduced in a controlled manner.
