Abstract:
We describe a simple technique for fabrication of tissue compensators using a simplified moiré contouring camera mounted on a commercial simulator. It is shown that high-quality optical enlargement of moiré photographs can be employed to make tissue compensators quickly using 0.4 mm lead sheets. Phantom measurement shows that this technique accurately compensates an irregularly shaped surface.
