The Monaco system is used to make treatment plans for patients with prescriptions for external beam radiation therapy. The system calculates dose for photon and electron treatment plans and displays, on-screen and in hard-copy, two- or three-dimensional 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

Monaco is a radiation treatment planning system that first received FDA clearance in 2007 (K071938). The modified system received clearance in 2009, when Volumetric Modulated Arc Therapy (VMAT) planning capability was added (K091179), again when Dynamic Conformal Arc planning was added (K110730), and electron planning, support for stereotactic cones, and SUV calculation were added (K132971). Specialty image creation was added in 2015 (K151233), and adaptive planning and dose calculation in the presence of a magnetic field (e.g., MR-Linac) was added in 2018 (K183037). A 510(k) was filed in 2017 for the addition of carbon ion planning. The 510(k) was withdrawn because there was no hardware cleared for the US market capable of delivering carbon ion plans. Monaco's carbon ion planning functionality remains licensed off and inaccessible to US users.

The Monaco system accepts patient imaging data and "source" dosimetry data 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 Physicist, can 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. The Monaco system then produces a display of radiation dose distribution within the patient, indicating doses to the target volume and surrounding structures. The "best" plan satisfying the clinican prescription is then selected, one that maximizes dose to the target volume while minimizing dose to surrounding healthy volumes.

Here's a summary of the acceptance criteria and study information for the Monaco RTP System based on the provided text:

Acceptance Criteria and Reported Device Performance

Study Information:

1. Sample size used for the test set and the data provenance:

   • Test Set Sample Size: Not explicitly stated as a number of cases or patients. The validation testing involved "simulated clinical workflows using actual patient data, such as patient images."
   • Data Provenance: "Actual patient data, such as patient images." The country of origin is not specified, but the context of an FDA submission implies a focus on data relevant to the U.S. market, though not exclusively. The study was retrospective in the sense that it used pre-existing "actual patient data."

2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

   • This information is not provided in the document. The adjudication of ground truth for the test set is not explicitly detailed.

3. Adjudication method for the test set:

   • The document states that plans are "reviewed and approved by qualified clinicians and may be subject to quality assurance practices before treatment actually takes place." However, for the specific test set used in validation, the adjudication method (e.g., 2+1, 3+1 consensus) is not explicitly described. The testing involved "pre-defined pass/fail criteria" that were "equivalent to that of the predicate, K183037."

4. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

   • A multi-reader multi-case (MRMC) comparative effectiveness study was not performed. The device is a treatment planning system, not an AI-assisted diagnostic tool for human readers in the traditional sense discussed in MRMC studies.

5. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

   • Yes, the primary validation was effectively a standalone performance evaluation of the software. The document states: "Verification tests were written and executed to ensure that the system is working as designed. Over 600 test procedures were executed, including tests to verify requirements for new product functionality, tests to ensure that risk mitigations function as intended, and regression tests to ensure continued safety and effectiveness of existing functionality." This describes an algorithm-only evaluation against predefined criteria.

6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

   • The "ground truth" for the test set verification was based on pre-defined pass/fail criteria and ensuring the system's calculations and functionality matched expectations established by the predicate device (K183037) and internal Elekta requirements. It also relied on "simulated clinical workflows using actual patient data" to ensure the system produced expected dose distributions and plan outputs. It is not framed as comparing to pathology or long-term outcomes data, but rather the accurate computation and display of dose distributions as per established physics and clinical planning principles.

7. The sample size for the training set:

   • The document does not specify a distinct "training set" for the Monaco RTP System. As a radiation treatment planning system, it relies on physics models and algorithms rather than machine learning models that typically require a training set in the AI sense. The development likely involved extensive testing and calibration against known physics principles and clinical data, which is distinct from a machine learning training set.

8. How the ground truth for the training set was established:

   • Since a distinct "training set" in the machine learning context is not mentioned, the concept of establishing ground truth for it is not applicable based on the provided text. The accuracy of the system is established through rigorous verification against physics models, calculations, and clinical expectations, rather than learning from a labeled training dataset.

1. Table of acceptance criteria and reported device performance:

2. Sample size used for the test set and data provenance:

• Test Set Sample Size: The document mentions "actual patient data" was used for simulated clinical workflows and algorithm testing, but it does not specify the sample size of this patient data.
• Data Provenance: The document does not specify the country of origin. It indicates the data was "actual patient data," but does not state whether it was retrospective or prospective.

3. Number of experts used to establish the ground truth for the test set and their qualifications:

• The document states that "qualified clinicians" review and approve treatment plans and that the process "can be performed such that no human subjects are exposed to risk." This implies that the validation testing was based on expert consensus or established clinical standards rather than live patient outcomes. However, the number of experts and their specific qualifications are not specified.

4. Adjudication method for the test set:

• The document mentions that treatment plans are "reviewed and approved by qualified clinicians," and that a "flaw in the treatment plan [could] escape the notice of the qualified professionals." This suggests a review process by experts. However, a formal adjudication method (e.g., 2+1, 3+1) is not explicitly described.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done:

• No, an MRMC comparative effectiveness study was not done. The document explicitly states: "Clinical trials were not performed as part of this product."

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

• Yes, a standalone component was done for algorithm testing. The document states: "Algorithm testing verified the accuracy of the new dose calculation algorithm in Monaco 5.40 using the same test methods as the predicate version of Monaco." This implies evaluation of the algorithm's performance independent of a human user.

7. The type of ground truth used:

• The ground truth appears to be based on established clinical standards and expert review/consensus rather than direct pathology or outcomes data from clinical trials. The document mentions "pre-defined pass/fail criteria" and validation against "simulated clinical workflows using actual patient data." The acceptance criteria focused on demonstrating "equivalent accuracy" to the predicate device, which would have its own established standards.

8. The sample size for the training set:

• The document does not specify a training set sample size. The focus of the provided text is on validation and verification testing of the already developed Monaco RTP system, which includes a new dose calculation algorithm. It does not describe the development or training phase of the algorithm itself.

9. How the ground truth for the training set was established:

• Since a training set is not explicitly mentioned and the document focuses on the validation of an existing system's new algorithm, the method for establishing ground truth for a hypothetical training set is not described.

Summary of Device Validation as per the Document:

The provided document indicates that the device's safety and effectiveness were demonstrated through:

• Substantial Equivalence: Comparison to legally marketed predicate devices (MOSAIQ K141572) and a reference device (The ViewRay (MRIdian) Linac System K162393) based on intended use and technological characteristics (detailed in tables on Pages 8-9).
• Non-Clinical Testing: Verification tests to ensure the system works as designed, including:
  • Verification of new product functionality requirements.
  • Ensuring installation as intended.
  • Regression tests for continued safety and existing functionality.
• Simulated Clinical Workflows: Validation testing performed using simulated clinical scenarios, without human subjects.

This approach is common for information systems and record-keeping devices where the primary function is workflow management, data integration, and safety checks, rather than direct diagnostic interpretation or image analysis using AI. The "level of concern" for the software was identified as "major" due to its interface with linear accelerators and responsibility for detecting mismatches, which could lead to serious injury if it failed. Therefore, the non-clinical and simulated testing would have rigorously focused on these critical safety functions.
