iDCalc is an application oriented to radiotherapists and medical physicists. It helps with several routine computations used in radiation therapy and nuclear medicine.

• Percent Depth Dose (PDD)
• Normalized Peak Scatter Factor (NPSF)
• Decay of frequently used isotopes from a calibration date to any future or present day.
• Equivalent Square and Equivalent Diameter.
• Conversion between several Radiation Quality specification indexes.

iDCalc has a built-in library of typical radiation beams with nominal energies from 2 MV to 50 MV. From this library the user can compute Percent Depth Dose (PDD) and Normalized Peak Scatter Factor (NPSF) for any energy in the valid quality range using d80 as the index to enter beam energy.

The PDD can be computed for different field size, source to skin distance and depth.
