Utilization of a commercial prostate brachytherapy planning system for 3D treatment planning of ophthalmic tumors.
The 3D brachytherapy transperineal ultrasound implant (B3DTUI) program by the Multimedia Medical System has been adopted for eye plaque treatment planning. The post op CT digitization option was selected to enter the actual seed coordinates present in the eye plaque. Although the B3DTUI algorithm is designated to calculate a permanent dose values, the described procedure allows determination of the dose distribution as the dose rate values. The dose computation program utilizes updated source quantities recommended by the AAPM TG-43 formalism, such as air kerma strength, dose rate constant, radial dose function, and anisortopy factor function. As a result, more accurate dose distribution in the target is obtained than by using traditional dose computation formalism.
