Frequently Asked Questions for Temporal Temperature Scanners


General


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

ICI Has Been Responding to All Global Health Crises of this Millennium:  Prior to COVID 19, ICI was supplying governments, front-line health responders, non-profits, and corporations with the fever screening systems that were needed to contain the spread of SARS, H1N1, and Ebola.

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

Accuracy is extremely important with any Electrical Medical Device such as this according to the ISO 13154-2017 and FDA screening procedures may suffer due to lack of accuracy and sensitivity.

Is screening people for elevated temperatures difficult to implement? Do I need to be a trained thermographer to fever 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 Statutes and allow your program and process to grow with the ever changing landscape of these statutes.

What is a “blackbody” and when / why do I need it?

A black body is a reference “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 a black body thermal imagers will only produce relative temperature measurements which is not sufficient for human febrile (fever) screening according to ISO 13154-2017 and FDA.

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’s, can provide an estimated core temperature, as well as a surface temperature.

Thermal Imaging Systems


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. 

Are thermal imaging systems used for body temperature assessment considered medical devices?

Yes, when it comes to systems that are used in compliance with ISO 13154-2017 and have achieved an FDA 510(k) Certification they can then be classified as an EMD, Electrical Medical Device, or Imaging Thermometer.

Are thermal imaging systems effective for screening people for fevers in places like nursing homes, airports, businesses, and hospital emergency rooms?

Yes, elevated body temperature (EBT) screening is an extremely beneficial use of thermal imaging technology that is currently begin deployed globally for the detection of febrile (fever) symptoms.  It is not a diagnostic tool as diagnosis is a clinical practice, rather an adjunct tool that assists in EBT methods.

What is the ideal distance from the thermal camera to those being screened for elevated temperatures?

We will work with you to determine the appropriate distance for efficiently integrating elevated body temperature (EBT) screening into your specific workflow. When designing or laying out your specific workflow, please remember that the blackbody must be adjacent to or behind the individual being screened.

Infrared Thermometers


Can you take body temperatures with an infrared thermometer?

Infrared thermometers can be used to measure body temperatures from up to 15 centimeters away from the target zone and provide results in less than half a second. These devices are highly sanitary because they are non-contact, reducing the chance of spreading infectious diseases.

Are infrared thermometers accurate?

ICI’s non-contact thermometers have a margin of error of ± 0.3 °C on skin surface temperature screenings. Infrared thermometers read the surface temperature of a target — not the internal temperature. This means that for fever detection, an infrared thermometer can catch if someone has an elevated skin temperature, though this doesn’t necessarily indicate a fever.

How do I use a non-contact infrared thermometer?

ICI's HotSpot IR Non-Contact Thermometer
ICI HotSpot IR Non-Contact Thermometer

To properly use a non-contact infrared thermometer to scan body temperature, stand 5 – 15 centimeters away from your target. Power on the device and point it at the inside corner of the patient’s eye, holding still. The temperature reading will display within 1 second. Many devices, such as ICI’s HotSpot IR, are battery-powered. You can set an alarm to sound when a temperature reading is abnormally high. ICI’s infrared thermometer powers off automatically and lets you choose between Celsius and Fahrenheit for readings.

Where do you take temperature with an infrared thermometer?

Often, people using a handheld infrared temperature scanner will point the device at the patient’s forehead. However, this is a relatively cool part of the body. It’s best to point the thermometer at the inner canthus of the eye — right in the inner corner. This is the hottest part of the human face.
