Indications for Use

The Thermidas IR System is for adjunctive use in addition to other clinical diagnostic procedures for diagnostic imaging for thermally significant indications of all skin regions of the human body. The system is for reviewing and reporting of temperature patterns and changes. The significance of the value of these thermal patterns is determined by professional investigation. The system is not intended for absolute temperature measurements. The Thermidas IR system is intended for use by trained technical personnel.

Device Story

System captures naturally emitted infrared radiation from human skin via off-the-shelf thermal imaging camera (FLIR A615); processes data via Thermidas Imager software on Windows workstation; produces quantitative thermal maps/images on display. Used in clinical settings by trained technical personnel. Software allows real-time viewing, storage of images/video, and manual analysis tools (color scale adjustment, region-of-interest statistics, reporting). Healthcare providers use visual thermal patterns and relative temperature variations as adjunctive information to support clinical diagnostic procedures. Device does not provide absolute temperature measurements or automated diagnostic conclusions; clinical decision-making relies entirely on professional interpretation of thermal findings.

Clinical Evidence

No clinical data; bench testing only. Device performance validated through compliance with standards including IEC 62304, EN 60601-1, and EN 60601-1-2.

Technological Characteristics

Microbolometer-based infrared camera (640x480 resolution); detects temperature differences down to 50 mK. Gigabit Ethernet connectivity. Windows-based workstation. Standards: EN ISO 13485:2016, EN ISO 14971:2012, IEC 62304:2015, EN 60601-1:2006+A1:2013, ANSI/AAMI ES60601-1:2005/(R)2012.

Indications for Use

Indicated for adjunctive diagnostic imaging of all human skin regions to detect thermally significant temperature patterns and changes. Intended for use by trained technical personnel. Not for absolute temperature measurement.

Regulatory Classification

Identification

A telethermographic system for adjunctive diagnostic screening for detection of breast cancer or other uses is an electrically powered device with a detector that is intended to measure, without touching the patient's skin, the self-emanating infrared radiation that reveals the temperature variations of the surface of the body. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

## Background

The ability to use Infrared technology to measure temperature variations and patterns of the body's service is commonplace technology.

Thermal imaging devices are non-invasive systems that do not touch the patient's body. The devices use infrared radiation technology to detect, measure, and quantify patterns and variations in skin temperature. The data is converted via software using algorithmic derivatives to an image on a computer screen.

Thermal imaging is a technique that can be employed by trained medical professionals and used as an adjunctive diagnostic screening tool (in conjunction with medical examination and other diagnostic tests) to detect skin temperature variation.

#### Device Description

The Thermidas IR System consists of an off-the-shelf thermal imaging camera, a mount for the camera and a Windows workstation running the Thermidas Imager software. The Thermidas IR System is a non-invasive medical device which uses infrared radiation naturally emitted by the patient, which senses variations in temperature. The captured data is processed by software producing a quantitative image on the computer screen. The medical professional can use the image to review, analyze, investigate, and quantify the temperature of the objects that are

imaged.

# Comparison of Intended Use and Principle of Operation:

Thermal sensor technology is essentially the same among various products regardless of technical specifications or applications used. Thermal imaging captures and records objects within the view of the camera using the captured object's naturally emitted infrared radiation.

The devices use infrared radiation technology to detect, measure, and quantify patterns and variations in skin temperature. The data is converted via software using algorithmic derivatives to an image on a computer screen.

As used in the medical field the information from infrared devices are strictly limited to thermal findings. The medical professional/reviewer may use information gathered from the devices and subsequent image such as location of findings, distribution of thermal patterns, and intensity to

{7}------------------------------------------------

make a thermal correlation with expected or abnormal patterns for the imaged region of the body.

The Thermidas IR System is substantially equivalent to the intended use, principle operation and similar software features the already FDA-cleared red-Hot Thermal Imaging Systems (K171928). Please refer to 510(k) summary, premarket notification and additional information for the Med-Hot Thermal Imaging Systems predicate device as set forth in Section 12 of this application.
