Intended Use

The intended use of Puma is to allow the radiation therapist to deliver treatment to the patient via linear accelerator (linac). This entails selection of the patient, selection of the day's correct treatment for the patient, set up, and delivery of the treatment fields and recording of the treatment. Puma supports auto-sequencing, a process of automatically downloading a group of fields or segments from the record and verify system to the control of the linear accelerator sequentially, without user intervention. In addition, Puma also supports IMRT (Intensity Modulated Radiation Therapy), a process of shaping, modifying and moving the beam around a target to maximize the dose at the target and minimize the dose to normal structures.

AI/ML Overview

Here's an analysis of the provided text regarding the acceptance criteria and study for the Prowess Puma device:

The provided text (K100801 for the Puma device) is a 510(k) summary, which focuses on demonstrating substantial equivalence to predicate devices rather than establishing novel safety and effectiveness criteria through extensive clinical trials. As such, the information on specific acceptance criteria and detailed study results, particularly for standalone performance or comparative effectiveness with human readers, is limited.

Here's a breakdown of the requested information based on the provided document:


1. Table of Acceptance Criteria and Reported Device Performance

The document doesn't explicitly state quantitative acceptance criteria or performance metrics in a table format. Instead, it relies on general statements of meeting specifications and being "as safe and effective" as predicate devices.

Acceptance Criteria CategoryAcceptance Criteria (Implicit)Reported Device Performance
Functional EquivalencePerform all functions described in the device description and intended use, similar to predicate devices."Puma has met its predetermined specifications, is substantially equivalent in performance as compared to the predicate devices, functions as intended, and is safe and effective for its specified use."
SafetyPrevent hazards identified in hazard analysis; protect patient and user."Key safety features of Puma include Defined privileges... Patient identification... Data locking... Verifying that the beams... A comprehensive risk analysis has been conducted. Detailed methods of mitigating these potential risks have been identified... and determined to be adequate. The benefits to patient and user outweigh any inherent risks..."
EffectivenessDeliver radiation treatment accurately, manage oncology information, support auto-sequencing and IMRT."The software has been found to perform as intended." "Functions as intended, and is safe and effective for its specified use."
Regulatory ComplianceComply with relevant FDA regulations, ISO standards, and quality system requirements."Quality system meets the requirements of ISO 13485, Medical Device Directive 93/42/EEC Annex II and FDA's Quality System Regulation, 21 CFR 820." "Complies with internationally recognized standards including ISO 14971:2007, IEC 62304, and IEC 62274."
Data Integrity/SecurityProtect patient health information, prevent data loss/alteration."Puma includes features specifically designed to protect confidential patient health information in accordance with the HIPAA regulations, including such security measures as password protection and access privilege set up and modification."

2. Sample Size Used for the Test Set and Data Provenance

  • Sample Size for Test Set: The document mentions "real patient cases" were used during beta testing at Auburn University, but does not specify the sample size (number of cases or patients) for this test set.
  • Data Provenance: The beta testing was conducted at "Auburn University," which is in the USA. The data was from "real patient cases" and was likely retrospective as it refers to "clinical cases" used for testing a developed device.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

  • Number of Experts: The document states "medical physicists/dosimetrists at Auburn University" conducted functional testing and "clinical physicists contracted by Prowess" verified risk mitigation. It does not provide an explicit number of experts.
  • Qualifications of Experts: "Medical physicists/dosimetrists" and "clinical physicists" are mentioned. No specific experience levels (e.g., "10 years of experience") are provided.

4. Adjudication Method for the Test Set

The document does not describe an explicit adjudication method (e.g., 2+1, 3+1). The testing involved "medical physicists/dosimetrists" and "clinical physicists" validating the system, implying their professional judgment served as the benchmark, but the process for resolving disagreements is not detailed.


5. 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

  • MRMC Study: No, an MRMC comparative effectiveness study involving human readers assisting with or without AI was not conducted or described.
  • Effect Size: Therefore, no effect size for human reader improvement with AI assistance is reported. The Puma device is a record and verify system, not primarily an AI-driven diagnostic or interpretative tool designed to "assist human readers" in the typical sense of AI-enabled image analysis.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

  • Standalone Performance: The non-clinical tests involved "Verification and validation of the software... Functional testing was conducted both in-house and by medical physicists/dosimetrists." This implies extensive standalone (algorithm only) testing against predetermined specifications. The core function of Puma is as a "record and verify system" that automates certain processes (like auto-sequencing), meaning its performance inherently relies on the algorithm operating correctly without continuous human intervention during those automated steps. The clinical physicist/dosimetrist involvement was to validate these functions.

7. The Type of Ground Truth Used

The ground truth for the testing appears to be based on:

  • Predetermined Specifications: The software "has met its predetermined specifications."
  • Expert Consensus/Clinical Judgment: Functional testing by "medical physicists/dosimetrists" and verification by "clinical physicists" against "real patient cases" implies that the correct operation and output were judged against established clinical practice and expert knowledge in radiation therapy planning and delivery.
  • Comparison to Predicate Devices: The overall goal was to demonstrate substantial equivalence, meaning the device's performance aligned with that of legally marketed, safe, and effective predicate devices.

8. The Sample Size for the Training Set

The document does not specify any sample size for a training set. As a record and verify system, especially one cleared in 2010, it's highly unlikely that it relied on machine learning models requiring large "training sets" in the modern AI sense. Its development would have followed traditional software engineering and validation processes against designed specifications.


9. How the Ground Truth for the Training Set Was Established

As no training set is described (due to the nature of the device and the development era), the method for establishing its ground truth is not applicable/not provided.

Device Description 4.

Puma is a medical device, which allows the user to deliver radiation treatment on linear accelerator to a patient. The software has been developed to be a record and verify system that also manages oncology medical information in order to simplify the oncologist administrative tasks and to optimize the quality of patient treatment. It is a Windows® based system, which uses a single database that can be accessed by any Puma client station in the treatment facility. Additionally, Puma is capable of performing such functions as:

  • Recording treatments delivered by the linear accelerator ・
  • Managing patient schedules -
  • Managing schedules for resources such as treatment machines and personnel -
  • Maintaining a central repository of treatment plans and records -

Intended Use 5.

The intended use of Puma is to allow the radiation therapist to deliver treatment to the patient via linear accelerator (linac). This entails selection of the patient, selection of the day's correct treatment for that patient, set up, and delivery of the treatment fields and recording of the treatment. Puma supports auto-sequencing, a process of automatically downloading a group of fields or segments from the record and verify system to the control of the linear accelerator sequentially, without user intervention. In addition, Puma also supports IMRT (Intensity Modulated Radiation Therapy), a process of shaping, modifying, and moving a beam around a target to maximize dose at the target and minimize the dose to normal structures.

Summary of Comparisons to Predicate Devices 6.

Puma is substantially equivalent to the predicate devices, Siemens' Lantis Treatstation and Varian's 4DITC, for purposes of FDA clearance for commercial distribution, as demonstrated and documented in this premarket notification submission. It has the same intended use and indications for use. In addition, the rationalization for substantial equivalence is further evidenced through discussion of similar technological characteristics between Puma and the predicates, as well as test results, which prove that Puma is as safe and effective as the predicate devices.

Summary of Technological Considerations 7.

Puma has many of the same technological characteristics as the predicate devices. There is a limited amount of distinguishing factors when comparing Puma to the predicates, and those features that are different do not affect safety or effectiveness. This is described in detail in Section VII: Substantial Equivalence Comparison.

Summary of Non-clinical Tests 8.

A hazard analysis was completed for Puma. Methods for preventing such hazards were detailed (Section VIII). Verification and validation of the software was conducted in house according to the Verification and Validation (V&V) Protocol, Puma Testing Protocol, and test results are included in Section IX of this submission. Functional testing was conducted both in-house and by medical physicists/dosimetrists at Auburn University. These tests have demonstrated that Puma has met its predetermined specifications, is substantially equivalent in performance as compared to the predicate devices, functions as intended, and is safe and effective for its specified use.

Summary of Clinical Tests 9.

Although clinical testing is not required to demonstrate substantial equivalence in safety and effectiveness, we elected to conduct testing at Auburn University using real patient cases. We feel that

{2}------------------------------------------------

no matter how carefully a product is tested at the manufacturer's facility, such testing cannot replace actual use of the device in a clinical setting. As such, we consider both in-house testing and beta testing at a user site during device development.
