Clinical evaluation of fever-screening thermography: impact of consensus guidelines and facial measurement location - Finding: May provide an effective alternate approach.

As discussed further below, scientific studies support that certain telethermographic systems, also known as thermal imaging systems, may be used to measure surface skin temperature. These systems include an infrared thermal camera and may have a temperature reference source. In this document, they are referred to as thermal imaging systems.

Is screening people for elevated temperatures difficult to implement? Do I need to be a trained thermographer to temperature screen?

Any system utilized for this application should be either a “plug and play” ready to use system or have the capability of being utilized in a more integrated manner.  How these are deployed is at the end user’s discretion, however, it is best to operate under the ISO 13154-2017 / FDA guidance and allow your program and process to grow with the ever-changing landscape of these statutes.

How much does accuracy matter when using thermal imaging for elevated temperature monitoring?

Accuracy is extremely important with any thermal imager used for temperature screening. We follow the best practice recommendations outlined by ISO 13154-2017 and FDA guidance documents to maximize accuracy and get the most precise results.

How does a thermal imaging system differ from a thermometer?

A thermal imaging system is a non-contact, non-invasive, passive imaging system that is measuring the thermal energy that is emitted, or given off, by the human body.  A thermometer is a contact device that is typically applied to the skin or other body cavity to achieve a core temperature measurement.

Thermal imaging systems, through proprietary software, can provide an estimated core temperature, as well as a surface temperature.

Are thermal imaging systems effective for diagnosing COVID-19?

No, elevated body temperature (EBT) screening devices are not diagnostic tools.  They are tools deployed for early detection to assist in diagnostics prior to potential contagious effects.

How long have you been helping integrate thermal elevated body temperature screening into workflows?

ICI responding to all global health crises of this millennium. Prior to COVID-19, ICI supplied governments, frontline health responders, non-profits, and corporations with the temperature screening systems that were needed to contain the spread of SARS, H1N1, and Ebola.

What is a temperature reference source and when / why do I need it?

A temperature reference is a “cavity” that is present in the field of view of the individual being screened. This reference device provides a constant steady temperature by which a Thermal imager can provide an absolute temperature measurement of the inner canthus(tear duct).  Without the use of an accurate temperature reference, thermal imagers will only produce relative temperature measurements, which is not sufficient for human febrile screening according to ISO 13154-2017 and FDA guidances.

"Our goal is to assist in opening our county by providing businesses with highly accurate, point-of-entry temperature screening systems."
