Premarket evidence — what FDA accepted

Device typesamd
source quote (p.12)
RayStation is a stand-alone software medical device intended for radiation therapy.
AlgorithmThe scientific concepts of a treatment planning system are patient and beam modeling, and algorithms for dose calculation and plan parameter optimization. With deep learning segmentation, the user can use trained deep learning models for automatic segmentation of new patient images. For electron beams RayStation calculates dose by the Monte Carlo technique. For photon beams RayStation calculates dose by the point kernel superposition method (a.k.a. Collapsed Cone) or a Monte Carlo algorithm for radiation transport (8.1 onwards). For proton beams RayStation uses either the pencil beam algorithm with the Fermi-Eyges formalism, or a Monte Carlo algorithm for radiation transport (6.0 onwards).

The scientific concepts of a treatment planning system are patient and beam modeling, and algorithms for dose calculation and plan parameter optimization. With deep learning segmentation, the user can use trained deep learning models for automatic segmentation of new patient images. (The model training is performed offline on clinical CT and structure data.) For electron beams RayStation calculates dose by the Monte Carlo technique. For photon beams RayStation calculates dose by the point kernel superposition method (a.k.a. Collapsed Cone) or a Monte Carlo algorithm for radiation transport (8.1 onwards). For proton beams RayStation uses either the pencil beam algorithm with the Fermi-Eyges formalism, or a Monte Carlo algorithm for radiation transport (6.0 onwards).
Adaptive (vs locked)Yes
source quote (p.15)
Adaptive replanning allows the user to adapt the treatment to a changing patient geometry. Reasons for when a patient is selected for replanning can vary between treatment protocols. Replanning should be performed when the plan is no longer suitable for treatment and when it has become necessary to adapt the plan to the new circumstances.
PCCPNo
Cybersecurity addressedYes
source quote (p.26)
Cybersecurity and Interoperability requirements were assessed per FDA guidance's "Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions (Sept 2023)". The cybersecurity analysis showed that the cybersecurity risks are mitigated, and the residual risk is acceptable. The devices are secure for use in their intended environment and methods are in place for ensuring security throughout the total product lifecycle.

FDA source did not state a quantitative performance metric — non-reporting is itself the signal.

Each value carries its own analysis unit and task — never compare or pool across devices. Source: 510(k) summary PDF.
