A thermology expert tells IPVM "95 to 99% of people" are doing fever screening "wrong" and said "unjustified" compensation algorithms are "unacceptable" and "insane" (many new fever camera vendors, such as Dahua, deploy such algorithms).
UPDATE 8/31: the expert updated his language in an email to IPVM, see this comment for his preferred version.
IPVM interviewed Dr. Robert Schwartz, Chairman of the Board of the American Academy of Thermology. The AAT covers all thermal imaging medical applications, including fever screening.
For this interview, which has been condensed and edited for length and clarity, IPVM discussed the many mistakes operators make when fever screening, the rise of handhelds, whether the FDA should be doing more enforcement, and more, including:
"95 to 99% Of It Is Being Done Wrong"
"First We've Heard of This": Unjustified Compensating Algorithms "Unacceptable"/"Insane"
System Without Blackbody "Isn't Reliable" Without Calibration
Simultaneous Screening Means "You're Not Getting Accurate Temperature"
"No Good Evidence" For Forehead Screening By Fever Cameras
"6-8 Feet" Is "Ideal" Distance For Fever Cams
"You Can't Measure Skin Temperature Through Baseball Hats"
Handheld IR Thermometers "Pretty Useless" Without Best Use Recommendations
