Software for 3D images and Dose
Distribution Calculation

The “AMIGOBrachy” is (a) planning software for
treating cancer with brachytherapy sources de-
veloped in MATLAB at the Nuclear Engineering
Center. The main resources and tools offered
by the software AMIGOBrachy are: Acquisition
of tomographic images of clinical diagnoses
of patients and engagement with the Monte
Carlo code MCNP6 to calculate 3D dose distri-
bution in the patient; modeling of radioactive
