No
The description focuses on the hardware components, control console functions, and applicator detection mechanism, none of which indicate the use of AI or ML. The "Mentions AI, DNN, or ML" section also explicitly states "Not Found".
Yes.
The device is intended for superficial radiotherapy treatments of primary malignant epithelial neoplasms of the skin and keloids, which are conditions requiring medical intervention. The device's function is to directly treat these conditions using x-rays, thus providing a therapeutic benefit.
No
The device is intended for superficial radiotherapy treatments of skin conditions and keloids, functioning as a treatment delivery system, not for diagnosing.
No
The device description clearly outlines multiple hardware components including a control console, base unit with high voltage generator and x-ray tube, a red-diode laser, and physical applicators. While software is likely involved in controlling these components, the device is fundamentally a hardware system for delivering radiation therapy.
Based on the provided information, the Sensus Healthcare SRT-100+ System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the system is for "superficial radiotherapy treatments of primary malignant epithelial neoplasms of the skin and keloids." This is a therapeutic application, not a diagnostic one.
- Device Description: The description details a system that generates and delivers low energy x-rays for treatment. It does not involve the examination of specimens derived from the human body (like blood, tissue, etc.), which is a key characteristic of IVD devices.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, detecting analytes, or providing diagnostic information based on in vitro testing.
Therefore, the SRT-100+ System is a therapeutic medical device, specifically a radiotherapy system, and not an IVD.

Device Description
The Sensus Healthcare SRT-100+ is a complete, stand-alone, x-ray radiation therapy system. It consists of four separate components: (a) control console; (b) base unit; (c) red-diode laser; and (d) applicators.
- (a) 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.
- (b) 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: (a) 0.10 mm Al at 20 to 30 kV: (b) 0.45 mm A1 at 50kV: (c) 0.75 mm Al at 70 kV; and (d) 1.15 mm Al at 100 kV; into the beam path depending on the kV setting selected by the operator.
- (c) Red-Diode Laser: A red-diode laser is integrated with the SRT-100+ 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.
- (d) Applicators: The system is shipped with a set of interchangeable treatment applicators, which define the source to skin distance (SSD) and the diameter of the treatment beam's exposure. The applicator size, therefore, determines the amount of total dose delivered per minute to the lesion and the actual area that will be treated by the system's x-ray beam. Each applicator is embedded with a unique magnet binary combination, which allows the system to automatically detect an applicator as it is mounted on the x-ray port. This provides the system with the information about the applicator's SSD and diameters, which allows it to correlate the applicable dose rate for each applicator that is attached to the x-ray port, thus allowing for a precise and user-error-free dose rate per minute calculation. There are a variety of applicator sizes available for use with the Sensus Healthcare SRT-100+ System, driven by the treatment modality.

The SRT-100+™ System is intended for use by a physician and other specially-qualified individuals properly trained in the system's use, science, and application.
7
Caution: Federal law restricts this device to sale by or on the order of a physician.
Technological Characteristics/Principles of Operation
The SRT-100+ produces and emits filtered, low energy (20, 30, 50, 70, and 100 kV) xray radiation, which is electrically generated using a conventional metal ceramic x-ray tube (Comet MXR-100). 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. When treating keloids, typically 1 to 4 fractions are employed, delivering a total dose in the range of 10 to 40 Gy.
Review of Clinical Literature
A summary of multiple clinical studies for the treatment of keloids and supporting literature has been collected, reviewed, and a clinical evaluation report scripted in support of this 510(k). The literature collected and reviewed supports Sensus Healthcare's claims of safety and efficacy for the application of superficial radiotherapy treatments of primary malignant epithelial neoplasms of the skin and keloids. Applications include: (a) basal cell carcinoma; (b) squamous cell carcinoma; (c) Metatypic carcinoma; (d) cutaneous appendage carcinoma (e) Kaposi's
8
Sarcoma; and (f) the treatment of keloids. Keloids are benign fibrous growths that arise from proliferation of dermal tissue typically arising from injuries to skin tissue.
Summary of Non-Clinical Performance Testing
All of the Sensus Healthcare SRT-100+ capabilities are also found in the previously cleared SRT-100 Vision System predicate device; and similar capabilities. The Sensus Healthcare SRT-100+ System, as configured, has been engineered and tested to meet Sensus Healthcare product requirements, required electrical and mechanical safety standards, and meet clinical expectations. All testing of the SRT-100+ System was performed in accordance with defined test cases with clearly delineated acceptance criteria. Additionally, FDA consensus standards and recognized ISO and IEC standards (e.g., IEC 60601-1 3rd edition) were employed for the bench testing, functional testing, and overall system performance testing of the SRT-100+. Furthermore, all testing was performed by qualified and accredited independent laboratories.

Substantial Equivalence Discussion
Sensus Healthcare SRT-100 Vision (K150037)
The SRT-100+ was designed using the critical components of the SRT-100 Vision system. including the same X-ray tube for delivery of radiation and the same control boards/PCBs that control the unit. The SRT-100+ has a contracted indication for use when compared to the SRT-100 Vision with the removal of the imaging capabilities (ultrasound module) and a removal of the electronic brachytherapy treatment. Functionally, the unit can perform radiation emissions in the 20, 30, 50, 70, or 100 kV range as opposed to the Vision's larger 20, 30, 50, 60, 70, 80, 90, or 100 kV range. Furthermore, the SRT-100+ has four (4) filtration options vs six (6) filtration options on the SRT-100 Vision. The unit has an articulating arm similar to the predicate device that is used to position the X-ray head for delivery of therapy. During treatment, the same applicators and applicator tips that are attached to the X-ray head of the SRT-100 Vision are used on the SRT-100+. The device is similar in size, dimensions, and
10
weight where both devices are mounted on a baseplate attached to castors for ease of mobility and positioning during installation and operation of the device.
Sensus Healthcare SRT-100 (K123985)
The SRT-100 system was originally designed by Topex Inc. and cleared under 510(k) K063456 on January 09, 2007. The Topex SRT-100 and associated intellectual properties (IP) were acquired by Sensus Healthcare in 2010. The SRT-100 user requirements were reviewed along with the SRT-100 Vision user requirements during the development of the SRT-100+ system. Functionally, the SRT-100 can perform radiation emissions in 50, 70, or 100 kV range as opposed to the SRT-100+'s expanded 20, 30, 50, 70, or 100 kV range. The core functionality of the SRT-100+ is very similar to the SRT-100 including comparable size, weight, and dimensions, but ultimately the SRT-100 Vision was chosen as the predicate device due to similarity of subcomponents used in the device.
Conclusion Statement
All the SRT-100+ System's intended use can be found in the intended use of the predicate device and reference device. Any technological changes to the device are minor, primarily as it pertains to industrial design, and do not raise new questions of safety or effectiveness. Performance testing, along with verification activities demonstrate that SRT-100+ is as safe and effective, and performs as well as the predicate device. Therefore, SRT-100+ can be considered substantially equivalent to the predicate device.
