Actually, dual-imaging facilities allow obtainance of both mass and activity patient-specific distributions perfectly correlated, which are important to improve dose distributions estimations and radioimmunotherapy treatment planifications accuracy. Calculus methods at voxel level require both quantitative and qualitative validation to obtain improvements in patient-specific dosimetry. The present work presents advances on the development of a novel computational tool dedicated to 3D patient-specific dosimetry at voxel level; and its results analysis and visualization. With the aim of providing a dosimetric tool for planar and tridimensional methods at voxel level, as well as the development of a platform based on fullstochastic methods for α-, β- and γ-emitters used in radiopharmaceutical applications. DOSIS is based on the Boltzmann radiation transport equation to realize energy delivering calculations. Procedures for 2D and 3D dosimetry have been designed tacking into accont established formalism and standards on MIRD Pamphlets. Anatomic and metabolic images, and dose maps resulting of this calculus are analysed and procesed by a special developed and designed software. DOSIS has been preliminary validated on some standard clinic cases in comparison whith other standard procedures used commonly in radionuclide treatments, showing great accordance on its results and a friendly user usability. Finally, a dose calculation over a standard phantom is performed using DOSIS calculation code and FLUKA, validating the radiation transport code of DOSIS.
