Calculates optimal imager panel positions for a Varian linear accelerator, based on field size, collimator rotation and vertical imager position.

The spreadsheet can calculate optimal imager panel positions for a Varian linear accelerator, based on field size, collimator rotation and vertical imager position.

The spreadsheet will alert the user when the projected radiation field is larger than the extent of the imager. A graphical display of the imager panel with the projected radiation field size is shown.
