Of 6 devices submitted to CDC, 3 met the above criteria and were selected for testing: the FLIR ThermoVision A20M (FLIR Systems Inc., Boston, MA, USA), the OptoTherm Thermoscreen
(OptoTherm Thermal Imaging Systems and Infrared Cameras Inc., Sewickley, PA, USA), and the Wahl Fever Alert Imager HSI2000S (Wahl Instruments Inc., Asheville, NC, USA).
The device used in this study, OptoTherm's ThermoScreen
Infrared Fever Screening System, uses a thermal imaging camera to measure skin temperature by quantifying infrared energy emitted from the face.
Angela Hewlett and her colleagues evaluated the OptoTherm ThermoScreen
in the Emergency Department of The Nebraska Medical Center, UNMC's hospital partner during the height of the H1N1 pandemic from November 18, 2009 to January 9, 2010 to test the tool's viability in a practical clinical setting.
