Abstract
We propose a simple, compact, and accurate light guidance system for interventional CT.The system using intersecting laser beams is mounted on the CT gantry and ensures precise needle guidance even when the gantry is tilted. The device does not require additional software/hardware.Phantom simulations and clinical experiments have demonstrated an accuracy of +/- 1 degrees and +/- 1 mm.The laser guidance system for CT makes the intervention safer, faster, and more accurate.Keywords
