Radiotherapy planning software that isn't tied to the vendor's machine
editorialSoftware & Systems · early attempts · hardest part: regulatory, engineering, capital
A treatment planning system is a large per-site licence bound to one manufacturer's linear accelerator, and the dose physics underneath it is textbook material.
This is editorial, not a record. Registry entries are cited facts about things that exist; an opportunity is our argument about something that does not. The links to existing work are checked against the catalog — the judgment around them is ours, and you should disagree with it where you know better.
Treatment planning is sold with the accelerator, and the commercial planning system is a substantial recurring cost and a lock-in point: planning, delivery, and quality assurance are integrated by design. The dose calculation physics — Monte Carlo transport, pencil beam models — is published and taught. The moat is clinical validation, certification, and integration with a specific machine's control system.
Not the dose engine; credible open engines exist in the research world. What is missing is everything that makes one usable clinically: commissioning against a real accelerator, an auditable quality assurance workflow, DICOM-RT interoperability that survives contact with vendor implementations, and a regulatory route for planning software that determines a delivered dose.
Cancer centres where the planning licence is a material share of the budget, and the many regions with accelerators but insufficient physics support.
Desktop platform for medical image visualisation, segmentation, registration, and image-guided therapy research.
Collection of DICOM implementations and clinical imaging archive tooling used in production PACS deployments.
Zero-footprint web-based DICOM viewer for radiology and clinical research workflows.
None cited. Everything above is either reasoning about market structure or a claim you should check yourself. Where we could not source a number, we left it out rather than estimating one.
