Laser projection system for radiotherapy and CT-guided biopsy.
We devised a laser projection system combined with a CT scanner and radiotherapy treatment planning computer (CT stimulator). The irradiation field can be projected over a range of 180 degrees on the skin of a patient lying on the CT couch. For CT-guided biopsy, the system can project the skin entry point and needle direction.
