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.

### 5.4 Device Description
The SMILE-100 System is a breast thermography device with a visualization tool that helps a healthcare personnel to review, measure and analyze thermally significant indications in the breast region. It is intended to be used in the hospital, acute care settings, outpatient surgery, healthcare practitioner facilities or an environment where patient care is provided by qualified healthcare personnel.
SMILE-100 System consists of the following:
- An off-the-shelf FDA cleared thermal camera with its associated camera control software (i) provided by the thermal camera vendor for capturing and viewing thermal images
- An off the shelf laptop/desktop computer system with display, keyboard and mouse. (ii)
- SMILE-100 Software for viewing thermal patterns in thermal images (iii)
The SMILE-100 Software takes thermal images captured using off-the-shelf FDA-cleared thermal camera and provides various visualization options in multiple customizable views/palettes and also generates a report with quantitative thermal parameters and annotated images. The Software supports two user roles (i) a thermographer or imaging technician role and (ii) Expert thermologist role. The imaging technician captures thermal images and uploads them to the cloud-hosted SMILE-100 Software which performs image quality checks and submits to Expert. The Expert can select a temperature threshold for the SMILE-100 Software to highlight areas with thermal activity above the threshold in thermal images. The software makes no estimation of the thermal threshold. The software makes no determination regarding what the thermal patterns or relative temperature values mean. Expert thermologist needs to infer the meaning of high thermal activity and other areas of interest based on his/her visual interpretation of those patterns and thermal values.
#### 5.5 Indications for Use
SMILE-100 System is intended to review, measure and record skin temperature patterns and variations emitted from the human body. It is intended for use as adjunctive diagnostic imaging for thermally significant indications in the breast region. The significance of the value of these thermal patterns is determined by professional investigation. This device is intended for use by qualified healthcare personnel trained in its use. The system is not intended for absolute temperature measurements. The system is not intended to be used as a thermometry device.
