The Prescription window unifies all prescription related functions. Controls are provided to set dose calculation options, the prescription point, date and time of plaque insertion and removal, and a customizable table of central axis (CAX), tumor axis (TAX) or user defined dosimetry points which are updated continuously.

The buttons along the top of the window provide a quick method of setting most dose calculation options. The plaque insertion and removal calendar controls are used to set the implant duration. The Implant Calculator button in the removal group simplifies calculation of required seed strength.

The Prescribe to menu sets the dose prescription point. This is generally the apex of the tumor.

The Rx Menu up on the MacOS menu bar provides additional control over Rx related functions and parameters.

From the Rx units button along the lower border you can choose the display units for the prescription.
