Founded in 2002, as a spin-off from both Gustave Roussy and Institut Curie - two major cancer treatment centers in Europe - DOSIsoft is committed to design, develop and deliver patient-specific imaging and dosimetry software in Radiation Oncology and Nuclear Medicine to improve patient safety & treatment quality.


A continuous innovation and R&D investments at the crossroads of Dosimetry, Medical Imaging and Digital technologies, have made DOSIsoft become a leading dosimetry software company. Its solutions have been used successfully in over 600 hospital centers in nearly 60 countries around the world.
