Abstract
Objective:
We propose a simple, compact, and accurate light guidance system for interventional CT.
Materials And Methods:
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.
Results:
Phantom simulations and clinical experiments have demonstrated an accuracy of +/- 1 degrees and +/- 1 mm.
Conclusion:
The laser guidance system for CT makes the intervention safer, faster, and more accurate.
