Device Description
RayStation is a treatment planning system for planning, analysis and administration of radiation therapy and medical oncology treatment plans. It has a modern user interface and is equipped with fast and accurate dose and optimization engines. RayStation consists of multiple applications: - . The main RayStation application is used for treatment planning. - . The RayPhysics application is used for commissioning of treatment machines to make them available for treatment planning and used for commissioning of imaging systems. - The RayTreat application is used for sending plans to treatment delivery devices for treatment and receiving records of performed treatments. The device to be marketed, RayStation 11B, contains modified features compared to RayStation 11.0 as indicated below: A simplified license configuration of RayStation is marketed as RayPlan. RayPlan has a limited set of purchasable licenses and some modules will not be accessible. RayPlan is marketed as RayPlan 11B. EQD2 dose computation (new) - From photon and/or braction doses, it is possible to compute, deform and accumulate the two Gray equivalent (EQD2) dose. The computation of the EQD2 dose uses the biological linear quadratic model, which is also the basis for the already released biological optimization and evaluation functionality. Generation of synthetic CT from CBCT (new) - Two new methods (algorithms) for synthetic CT generation will be included. The synthetic CT images are created by combining information in the CBCT image and a CT image for the specific patient to allow for dose computation using the HU values in the image, as for regular CT images. In RayStation 11.0 it is possible to compute dose on CBCT images for photons using bulk density assignments. The added functionality will improve the photon dose calculation accuracy on CBCT images. Handling of LET and other RBE components (new) - This functionality enables possibility to compute and evaluate the dose weighted LET (Linear Energy Transfer) for proton and light ion plans. LET is an additional dosimetric measure that can be used to assess the radiobiological effect of the proton and light ion radiation. Radiobiological equivalent (RBE) dose is a derived quantity with dependence on both the physical dose and the LET. In RayStation 11.0, it is possible to compute and evaluate RBE doses.

The document explicitly states "Related to machine learning, there is no change compared to the predicate device."

No
This device is a software system used for planning, analysis, and administration of radiation therapy and medical oncology treatment plans. While it supports therapeutic efforts by providing tools for treatment planning and administration, it is not a therapeutic device itself as it does not directly administer therapy to the patient. It is a tool for healthcare professionals to prepare and manage treatments.

No

Explanation: RayStation is a treatment planning system for radiation therapy, which proposes treatment plans and is used to administer treatments. It does not diagnose diseases or medical conditions.

Yes

The device description explicitly states that RayStation is a "software system" and a "treatment planning system." While it interacts with hardware (treatment delivery devices, imaging systems), the device being submitted for 510(k) is the software itself, which performs the planning, analysis, and administration functions. The modifications described are also software-based (new algorithms, computation methods).

Based on the provided information, RayStation is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
  • RayStation's Intended Use: RayStation is a software system for radiation therapy and medical oncology. Its primary function is to propose and administer treatment plans based on user input and medical imaging data (CT, CBCT). It does not analyze specimens taken from the human body.
  • Device Description: The description focuses on treatment planning, dose calculation, and treatment delivery, all of which are related to the administration of therapy, not the analysis of biological samples.
  • Lack of IVD-related information: The document does not mention any analysis of biological specimens, laboratory procedures, or diagnostic markers, which are typical characteristics of IVD devices.

Therefore, RayStation falls under the category of a medical device used for treatment planning and delivery in radiation therapy and medical oncology, not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The test specification of RayStation 11B is a further developed version of the test specification of RayStation 11.0. This is supported by the requirements specification, for which the same is true. The successful verification and validation of RayStation 11B therefore support the substantial equivalence of the above RayStation versions.

EOD2 dose computation (new) – Validation for photon and/or braction doses were validated as part of the Clinical Evaluation for Brachy and User Site Validation demonstrates that the dose computation adequate for clinical use.

Generation of synthetic CT from CBCT (new) – Validation of improved photon dose calculation accuracy on CBCT images was performed in CBCT Conversion validation demonstrates that the dose computation adequate for clinical use.

Handling of LET and other RBE components (new) - Validation of dose weighted LET (Linear Energy Transfer) for proton and light ion plans were performed as part of the Proton PBS Monte Carlo validation. The validation demonstrates that the dose computation adequate for clinical use.

The determination of substantial equivalence is not based on an assessment of non-clinical performance data. However, the entire system verification and validation specifications and reports are included in the submission as required by a software device of major concern.

A number of different types of verification activities have been performed:
. System Tests of RayStation
Risk analysis-based tests for use error mitigation verification
. Unit and subsystem testing for low-level testing
. Dose engine validation including internal testing
User validation in cooperation with cancer clinics
. Reviews of design, code and Master Labeling

The data obtained from the verification show that system tests, unit and subsystem tests have passed, and the validations been completed successfully. The reviews of design, code and labeling are also passed.

From the successful verification and validation activities, the conclusion can be drawn that RayStation 11B has met specifications and is as safe, as effective and performs as well as or better than the legally marketed predicate device.
