AI/ML Overview

The provided text describes a 510(k) summary for the Sensus Healthcare SRT-100 Vision, an X-ray radiation therapy system with ultrasound imaging and red-diode laser pointing capabilities. It indicates that performance testing consisted of bench testing which demonstrated that the device "provided the same clinical capabilities as the predicate device" and that "the system successfully passed all tests required by IEC 60601-1, Part 2-8, Edition 1.1, 1999" and "tests developed internally for system characterization." Additional performance testing was also executed to "validate the operational characteristics associated with the Sensus Applicators." The ultrasound component was tested in accordance with IEC 60601-2-37 and the red-diode laser in accordance with IEC 60825-1.

However, the document does not provide specific acceptance criteria or the study details proving the device meets those criteria in a quantitative manner. It primarily focuses on the device's technical specifications, intended use, and adherence to various electrical and mechanical safety standards. There are no tables of acceptance criteria with reported performance values, no sample sizes for test or training sets, no details on expert adjudication for ground truth, and no mention of MRMC or standalone performance studies in a clinical context.

Therefore, the following information cannot be extracted from the provided text:

A table of acceptance criteria and the reported device performance: Not provided.
Sample size used for the test set and the data provenance: Not provided.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not provided.
Adjudication method for the test set: Not provided.
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and the effect size of how much human readers improve with AI vs without AI assistance: Not provided. The device is a therapy system, not an AI diagnostic tool.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not provided. The device is a therapy system, not an algorithm.
The type of ground truth used: Not provided. "Bench testing" is mentioned, implying engineering and safety compliance rather than clinical ground truth as typically understood for diagnostic AI.
The sample size for the training set: Not provided.
How the ground truth for the training set was established: Not provided.

The document states that the SRT-100 Vision's non-clinical performance testing "demonstrated that the output of the Sensus Healthcare SRT-100 Vision provided the same clinical capabilities as the predicate device (Sensus Healthcare SRT-100)." This suggests that the primary method of demonstrating effectiveness was through substantial equivalence to a previously cleared device, based on technical and safety performance rather than new clinical outcome studies. It also mentions "A summary of multiple clinical studies for the treatment of keloids and supporting literature can be found in Appendix D of this 510(k)," but the details of these studies are not included in the provided text.

Device Description:

The Sensus Healthcare SRT-100 Vision is a complete, stand-alone, X-ray radiation therapy system, with ultrasound capability. It consists of four major separate components:

Control Console: Specifically designed module housing the switches and indicators used by the operator to set up and execute X-ray exposures. The controls adjust the machine functions and settings only! There is no treatment planning capability. The Control Console is connected, through a cable, to the Base Unit.

Base Unit: The base unit consists of a cabinet containing the high voltage generator, power supply components, cooling system, and an arm/positioning mechanism on which the X-ray tube housing assembly is mounted. A series of Applicators are included, which are affixed to the X-ray port on the X-ray tube housing assembly to limit the X-ray beam and provide fixed Source-to-Skin Distance (SSD). The X-ray Tube-Housing Assembly contains a motorized filter mechanism, which moves the appropriate beam filter into the beam path depending on the kV setting selected by the operator.

Ultrasound Imaging: The Derma-Scan C Ultrasound System component (manufactured by Cortex Technology) is integrated with the SRT-100 Vision System and contains: (a) scanning main unit; (b) handheld probe and (c) a medical grade power supply to provide power to the computer. The ultrasound component is designed and tested to meet international safety requirements.

Red-Diode Laser: A red-diode laser is integrated with the SRT-100 Vision System. The laser is manufactured by U.S. Laser and is classified as FDA Laser Class 3A. The

application of the red-diode laser with the Sensus SRT-100 Vision has been tested in accordance with IEC 60825-1.

Intended Use:

The SRT-100 Vision is a low energy X-ray system, with ultrasound imaging capability, is intended for superficial radiotherapy treatment of primary malignant epithelial neoplasms of the skin and keloids. Applications include basal cell carcinoma, squamous cell carcinoma, Metatypic carcinoma, cutaneous appendage carcinoma, Kaposi's Sarcoma, and the treatment of keloids. Keloids are benign fibrous growths that arise from proliferation of dermal tissue typically arising from injuries to skin tissue.

The ultrasound capability, employed in a non-diagnostic mode, is used to assist the physician in identification of lesion location; and the selection of the correct cone applicator size and energy mode required for delivery of therapy. The Derma-Scan C Ultrasound component was initially cleared with an indication for use as an ultrasonic scanning system used to visualize the layers of skin, including bold vessels, and to make approximate measurements of dimensions in layers of skin and blood vessels, by ultrasonic means.

A red-diode laser is employed for the assisting with cone applicator placement. The laser is manufactured by U.S. Laser and is classified as FDA Laser Class 3A. The application of the red-diode laser with the Sensus SRT-100 Vision has been tested in accordance with IEC 60825-1. The test results can be found in Appendix J of this 510(k).

Prescriptive Statement

The SRT-100 Vision is intended for use by a physician and other specially-qualified individuals properly trained in the system's use and application.

There are some small black dots scattered around the word, possibly due to the image quality or texture of the original document.

Technological Characteristics/Principles of Operation:

The SRT-100 Vision produces and emits filtered, low energy (50, 70 and 100 kV) xradiation, which is electrically generated using a conventional ceramic X-ray tube. Provision is made to limit the x-radiation to a specified treatment field, and to control the radiation dose to the patient through selection and monitoring of energy, emission level and duration of emission. To mitigate effects of ionizing radiation on healthy cells, and to accumulate more damage in the neoplastic cells and keloids associated with scar tissue, the total dose is fractionated, which means distributing the total dose over a period of time. Typically, 8 to 12 fractions at a rate of 1 to 5 per week are used to deliver a total dose of 40-60 Gy, although larger PMENs may require up to 40 fractions over an 8-week period for a total dose of 80 Gy. 1 (Panizzon, R and Cooper, J. (Eds.) Radiation Treatment and Radiation Reactions in Dermatology, Springer Verlag, 2004, p. 75). When treating keloids, typically 1 to 4 fractions are employed, delivering a total dose in the range of 10 to 40 Gy. A summary of multiple clinical studies for the treatment of keloids and supporting literature can be found in Appendix D of this 510(k).

Non-Clinical Performance Testing:

Performance testing consisted of bench testing that has demonstrated that the output of the Sensus Healthcare SRT-100 Vision provided the same clinical capabilities as the predicate device. The system successfully passed all tests required by IEC 60601-1, Part 2-8, Edition 1.1, 1999 - Particular Requirements for the Safety of Therapeutic X-ray Equipment Operating in the Range 10 kV to 1 MV and also tests developed internally for system characterization.

Additional performance testing was executed to validate the operational characteristics associated with the Sensus Applicators. Schematics of the applicators and associated performance curves are located in appendix E of this 510(k).
