PHANTOM WITH PULSATILE ARTERIES TO INVESTIGATE THE INFLUENCE OF BLOOD VESSEL DEPTH ON PULSE OXIMETER SIGNAL STRENGTH

Phantom with Pulsatile Arteries to Investigate the Influence of Blood Vessel Depth on Pulse Oximeter Signal Strength

This paper describes a three-layer head phantom with artificial pulsating arteries at five different depths (1.2 mm, 3.7 mm, 6.8 mm, 9.6 mm and 11.8 mm).The structure enables formation of spatially and temporally varying tissue properties similar to those of living tissues.In our experiment, pressure pulses were generated in the arteries by an elec
