Independent calculation in seconds

Independent plan calculations can be a time consuming and error prone process as radiation oncology grows in complexity. ClearCalc, an independent calculation software, efficiently validates plan accuracy. Eclipse users save time with direct plan import—eliminating the need to import/export plan data—and those without Eclipse can export DICOM files with the standalone option.
