“…Infrared thermal imaging is mentioned as an appropriate technique for mass screening of fever [1]. The temperature of the inner canthus of the eye (T ca ) seems the most suited spot [2] although others argue that the average temperature of the face may be valuable as well, albeit in combination with other physiological parameters [3]. A recent review observed a wide range in fever detection sensitivity from 4 to 90%, while specificity ranged from 75 to almost 100% [4].…”

Several studies suggest that the temperature of the inner canthus of the eye (T ca ), determined with infrared thermal imaging, is an appropriate method for core temperature estimation in mass screening of fever. However, these studies used the error prone tympanic temperature as a reference. Therefore, we compared T ca to oesophageal temperature (T es ) as gold standard in 10 subjects during four conditions: rest, exercise, recovery and passive heating. T ca and T es differed significantly during all conditions (mean DT es 7 T ca 1.80 + 0.898C) and their relationship was inconsistent between conditions. Also within the rest condition alone, intersubject variability was too large for a reliable estimation of core temperature. This poses doubts on the use of T ca as a technique for core temperature estimation, although generalization of these results to fever detection should be verified experimentally using febrile patients.

“…This makes the technique favorable for epidemiological surveillance and massmedicine. In fact, we have already attempted to apply this technique for screening of individuals with suspected infection at a quarantine depot (Matsui et al, , 2010. We have already succeeded in diagnosing influenza patients in as little as 10 s per person.…”

Recently, nonrestrictive and noninvasive sensing techniques to measure vital signs have been actively researched and developed. This study aimed to develop a prototype system to monitor cardiac activity using microwave radar without making contact with the body and without removing clothing-namely, a completely noncontact, remote monitoring system. In addition, heart rate and changes in heart rate variability (HRV) during simple mental arithmetic tasks were observed with the prototype system. The prototype system has a microwave Doppler radar antenna with 24 GHz frequency and approximately 7 mW output power. The experiments were conducted with seven subjects (23.00Ϯ0.82 years). We found that the prototype system captured heart rate and HRV precisely. The strong relationship between the heart rates during tasks (rϭ0.96), LF (cross-correlationϭ0.76), and LF/ HF (cross-correlationϭ0.73) of HRV calculated from the prototype system and from electrocardiograph (ECG) measurements were confirmed. The proposed completely noncontact, remote method appears promising for future monitoring of cardiac activity as an indicator of changes in mental workload in workplaces.

“…This system enables medical inspection by measuring heart and respiratory rates, as well as body temperature by infrared thermography (Matsui et al, , 2010. A similar system is already being tested at the quarantine station at Naha Airport for domestic flights and at Narita International Airport in Tokyo.…”
