What DOSIsoft does
DOSIsoft is a privately held French medical device software company founded in 2002 as a spin-off from Gustave Roussy and Institut Curie, headquartered in Cachan with additional offices in Coral Gables, Florida and Montpellier, France. The company develops Class II medical device software for radiation oncology and nuclear medicine, with a portfolio spanning two platforms: PLANET (PLANET Onco for multi-modality imaging quantification and PLANET Dose for voxel-based personalized dosimetry in SIRT and molecular radiotherapy) and the ThinkQA Suite (Secondary Dose Check, EPIbeam for EPID-based pretreatment verification, and EPIgray for in vivo transit dosimetry). Core technology includes GPU-accelerated Collapsed Cone Convolution (CCC) dose calculation, AI-powered organ and lesion segmentation, and IBSI-compliant radiomics feature extraction (142 indices). Products carry FDA 510(k) clearances, EU MDR CE markings, ISO 13485 and MDSAP certifications, and are deployed across 800+ hospital centers in 80 countries.
The company generates revenue through software licensing and subscription contracts, one-time perpetual licenses with maintenance, and professional services for implementation and training. Go-to-market combines direct enterprise sales (France HQ, US office), exclusive global distribution through Elekta for ThinkQA products (integrated into Elekta ONE workflows), centralized procurement via UniHA for French public hospitals, and a global distributor network. DOSIsoft serves hospital radiation oncology departments (patient-specific QA, adaptive RT verification) and nuclear medicine departments (radionuclide therapy dosimetry for 90Y, 177Lu, 131I, 166Ho), with additional reach into MR-Linac centers (notably Elekta Unity). In May 2026 the company spun out DOSIsoft Theranostics as a dedicated entity to accelerate innovation in personalized nuclear medicine software beyond the Elekta channel.
