Abstract

The detection of body movements during MR examination could help in reducing motion artifacts or to get patient responses during functional magnetic resonance. It can be supported by a slit scanner, that combines a camera with a light stripe projector to obtain 3D coordinates of points forming the external surface of the body. In this work we propose a slit scanner prototype based on a miniaturized projector without moving parts. Just small sized hardware is required to analyze the video signal, operating in time domain instead of spatial domain. To accomplish this, the camera is placed with its pixel columns as more parallel as possible to the projected light stripes and the camera video signal is analyzed by a resistor transistor logic after analog processing.
