Abstract
In a phantom and in 37 patients, a simple laser guidance system for computed tomography (CT)-guided procedures used the software program of the CT scanner and a laser beam mounted on the CT gantry without need for additional software or components. The skin entry point and angulation of the target path were determined. Then the system projected the desired needle path (including compound angulation), allowing accurate needle placement in all cases, even in small lesions.
