PREDICATE DEVICE Monaco RTP System (K202789) ### IV. INTENDED USE / INDICATIONS FOR USE The Monaco system is used to make treatment plans for patients with prescriptions for external beam radiation therapy. The system calculates dose for photon, electron, and proton treatment plans and displays, on-screen and in hard-copy, two- or threedimensional radiation dose distributions inside patients for given treatment plan set-ups. The Monaco product line is intended for use in radiation treatment planning. It uses generally accepted methods for: - contouring - image manipulation - simulation - image fusion - . plan optimization - QA and plan review #### V. DEVICE DESCRIPTION The Monaco RTP System accepts patient diagnostic imaging data from CT and MR scans, and source dosimetry data, typically from a linear accelerator. The system then permits the user to display and define (contour) the target volume to be treated and critical structures which must not receive above a certain level of radiation, on these diagnostic images. Based on the prescribed dose, the user, a Dosimetrist or Medical {4}------------------------------------------------ Physicist, can then create multiple treatment scenarios involving the number, position(s) and energy of radiation beams and the use of a beam modifier (MLC, block, etc.) between the source of radiation and the patient to shape the beam. Monaco RTP system then produces a display of radiation dose distribution within the patient, indicating not only doses to the target volume but to surrounding tissue and structures. The optimal plan satisfying the prescription is then selected, one that maximizes dose to the target volume while minimizing dose to surrounding healthy volumes. The parameters of the plan are output for later reference and for inclusion in the patient file. Monaco planning methods and modalities: - Intensity Modulated Radiation Treatment (IMRT) planning . - . Electron, photon and proton treatment planning - . Planning for dynamic delivery methods (e.g. dMLC, dynamic conformal, Volumetric Modulated Arc Therapy (VMAT)) - . Stereotactic planning and support of cone-based stereotactic - . 3D conformal planning - . Adaptive planning (e.g. for the Elekta Unity MR-Linac) Monaco basic systems tools, characteristics, and functions: - . Plan review tools - . Manual and automated contouring tools - DICOM connectivity . - . Windows operating system - . Simulation - . Support for a variety of beam modifiers (e.g. MLCs, blocks, etc.) - . Standardized uptake value (SUV) - Specialty Image Creation (MIP, MinIP, and Avq) • - . Monaco dose and Monitor Unit (MU) calculation: - Dose calculation algorithms for electron, photon, proton planning . Monaco is programmed using C and C++ computer programming languages. Monaco runs on Windows operating system and off-the-shelf computer server/hardware. #### VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE The principles of operation of the proposed version of Monaco are the same as the currently cleared version of Monaco. The major changes in this release are enhancements to the proton functionality that was cleared under predicate device K202789. These include proton robust optimization, proton robust evaluation and proton linear energy transfer (LET). Robustness optimization and robust evaluation are extension to the cleared features in Monaco 6.0. The ability to calculate LET is a calculation option for Monaco users using proton treatment plan modality and the Monte Carlo algorithm. The functionality is an extension of the existing Monte-Carlo algorithm with no change to the high-level clinical workflow and no impact to accuracy of dose calculation for Monaco users. Some other non-significant changes are also included in this release. {5}------------------------------------------------ ### VII. SUMMARY OF PERFORMACE TESTING (NON-CLINICAL) Development, verification, and validation activities for the modified system were carried out in accordance with design controls as required by FDA's Quality System Requlation (21 CFR §820.30), applicable ISO 13485 Quality Management System requirements, ISO 14971 Risk Management requirements, and IEC 62304 requirements for software life-cycle processes. Non-clinical testing was performed to evaluate device performance and functionality in accordance with design and risk management requirements at subsystem, integration and system levels includinq interoperability. Documentation of software development and verification testing activities for Monaco is maintained in accordance with FDA's "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices," May 2005, for devices that pose a major level of concern (Class C per IEC 62304). Formal validation of the clinical workflows has been performed on a clinically representative production equivalent system by competent and professionally qualified personnel. The following validation testing was conducted regarding the LET functionality introduced in Monaco 6.1: - a. The LET to water and medium were calculated for monoenergetic spots in Monaco and Geant4 for a range of energies and materials. The results were quantitatively compared to each other as well as qualitatively compared to other published results. - b. LET distributions for complex multiple spot and multiple beam arrangements as well as plan summations were calculated in Monaco and compared to expected values as obtained through manual summation of individual spots according to the design equations. #### VIII. SUMMARY OF PERFORMACE TESTING (CLINICAL) No animal or clinical tests were performed to establish substantial equivalence with thepredicate device. The performance data demonstrate that the Monaco RTP System is as safe and effective and performs as well as the predicate device Monaco RTP System. ### IX. SUBSTANTIAL EQUIVALENCE CONCLUSION Monaco RTP System is substantially equivalent (SE) to the predicate device, Monaco RTP System (K202789). The intended use and indications for use are identical to the predicate device and the principles of operation remain unchanged. The technological characteristics are substantially equivalent to the predicate device; enhancements to existing functionality do not affect the fundamental scientific technology or raise different questions of safety or effectiveness of the device. The device safety and performance have been addressed by non-clinical testing in conformance with predetermined performance criteria, FDA quidance, and recognized consensus standards. The results of verification and validation as well as conformance to relevant safety standards demonstrate that the Monaco RTP System meets the established safety and performance criteria and is substantially equivalent to the predicate device.
