PARaDIM is a graphical user interface-based application for absorbed dose calculations in a variety of settings in nuclear medicine and radiation protection. It utilizes anatomically realistic tetrahedral mesh computational phantoms in combination with the well-validated multipurpose Particle and Heavy Ion Transport code System (PHITS) to compute region-level dose and 3D dose distributions with high speed and accuracy.

01 / VERSATILE
Antibody-, peptide-, or small molecule-based endoradiotherapy
External radionuclide exposure
3D dose calculation
02 / EASY
The methodology PARaDIM utilizes was previously only possible for professionals with an advanced understanding of a select few particle transport codes. PARaDIM requires no coding skills at all, and sophisticated simulations can be configured and run with just a few mouse clicks.
03 / FREE
As a service to the nuclear medicine community, PARaDIM is provided freely.
