o compatible with the DICOM-RT file format implementation from all three major vendors o GUI serves as a viewer for all data parsed from DICOM-RT o GUI also serves as a front end MCNP software tool (no MCNP experience required) o patient represented by rectangular grid (CT resolution that can be down-sampled ) o individual voxel density from CT data based on generic or custom calibration o option for density binning using 54 bins (accuracy better than 1%, Peppa et al 2013, Radiother Oncol. 106,S371) o elemental composition assigned using a look-up table of 23 human tissue composition bins (Schneider et al 2000, Phys Med Biol. 45, 459) o incorporates RTDose and MCNP output comparison tools (%D.d., isodose, DVH, g- index) o source represented by its phase space file (no library available) o no applicator library available o user must edit the generated input file to employ variance reduction and other speed enhancement techniques
