Intended Use
The SRT-100 Vision System is a low energy x-ray system, with ultrasound imaging capability, intended for superficial radiotherapy and electronic brachytherapy 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 Sarcoma; and (f) the treatment of 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 the selection of the correct cone applicator size. 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. The red-diode laser assembly is a commercial pointer device employed by physicians for improving the alignment of the focused beam.
Device Description
The Sensus Healthcare SRT-100 Vision is a complete, stand-alone, x-ray radiation therapy system. It consists of five separate components: (a) control console; (b) base unit; (c) ultrasound imaging; (d) red-diode laser; and (e) applicators. 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: (a) 0.10 mm Al at 20 to 30 kV; (b) 0.10 mm Cu at 50 to 100 kV; (c) 0.45 mm Al at 50kV; (d) 0.75 mm Al at 70 kV; (e) 1.15 mm Al at 100 kV; and (f) 4.0 mm Al at 50 to100 kV; into the beam path depending on the kV setting selected by the operator. Ultrasound Imaging: The Derma-Scan C Ultrasound System component is integrated with the SRT-100 Vision computer 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 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. 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 Vision System, driven by the treatment modality.

No
The description focuses on hardware components, control console functions, and automated applicator detection based on magnetic encoding. There is no mention of algorithms that learn from data or perform complex analysis beyond basic system control and measurement correlation.

Yes
The device is described as a "low energy x-ray system, with ultrasound imaging capability, intended for superficial radiotherapy and electronic brachytherapy treatments of primary malignant epithelial neoplasms of the skin and keloids," which are clear therapeutic applications.

No

The document explicitly states that the ultrasound capability, while initially cleared for visualization and measurement, is "employed in a non-diagnostic mode" for this specific device. Its function here is to assist in applicator selection for radiotherapy, not for clinical diagnosis.

No

The device description clearly outlines multiple hardware components including a control console, base unit, ultrasound imaging system, red-diode laser, and applicators. It is a complete, stand-alone x-ray radiation therapy system.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
  • Device Function: The SRT-100 Vision System is a therapeutic device that uses x-ray radiation and electronic brachytherapy to treat skin conditions. While it includes ultrasound imaging, its stated purpose is to assist in selecting the correct applicator size, not for diagnostic purposes on a specimen.
  • Intended Use: The intended use clearly states "intended for superficial radiotherapy and electronic brachytherapy treatments" of specific skin conditions. It does not mention any diagnostic testing of biological samples.
  • Device Description: The description focuses on the components related to generating and delivering radiation for treatment. The ultrasound component is described as being used in a "non-diagnostic mode" to assist with applicator selection.

Therefore, the SRT-100 Vision System is a therapeutic device, not an In Vitro Diagnostic device.

Device Description

The Sensus Healthcare SRT-100 Vision is a complete, stand-alone, x-ray radiation

therapy system. It consists of five separate components: (a) control console; (b) base unit; (c)

ultrasound imaging; (d) red-diode laser; and (e) applicators.

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.

5

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) 0.10 mm Cu at 50 to 100 kV; (c) 0.45 mm Al at 50kV; (d) 0.75 mm Al at 70 kV; (e) 1.15 mm Al at 100 kV; and (f) 4.0 mm Al at 50 to100 kV; into the beam path depending on the kV setting selected by the operator.

Ultrasound Imaging: The Derma-Scan C Ultrasound System component is integrated with the SRT-100 Vision computer 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 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.

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.

6

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 Vision System, driven by the treatment modality.

Intended Use:

The SRT-100 Vision System is a low energy x-ray system. with ultrasound imaging capability, intended for superficial radiotherapy and electronic brachytherapy 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 Sarcoma; and (f) the treatment of 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 the selection of the correct cone applicator size. 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.

The red-diode laser assembly is a commercial pointer device employed by physicians for improving the alignment of the focused beam.

Prescriptive Statement

Caution: Federal law restricts this device to sale by or on the order of a physician.

7

Technological Characteristics/Principles of Operation

The SRT-100 Vision produces and emits filtered, low energy (20 to 100 kV) x-ray radiation, which is electrically generated using a conventional 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, electronic brachytherapy, 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 and electronic brachytherapy 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 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.
