Introduction

Infrared thermography (IRT) has gained significant interest in medical applications for its potential in diagnosing various conditions. Smartphone-based IRT modules offer portability and affordability, leading to increased utilization in medical settings. However, differences in performance among these modules raise questions about their reliability for medical use.

Materials and methods

This study compared three smartphone-based IRT modules (SmartIRT—Hikmicro, FLIR One Pro, and Seek Thermal CompactPRO—which, according to their datasheets, exhibit comparable quality and parameters. Temperature stability, surface temperature of the body, and spatial uniformity of provided images were assessed using calibrated black body measurements and surface temperature monitoring.

Results

The Hikmicro module exhibited the most stable temperature readings, while FLIR One Pro showed the highest temperature increase over time. Seek Thermal CompactPRO demonstrated relatively better spatial uniformity. However, discrepancies in image resolution were noted, with FLIR One and Seek modules modifying image sizes through post-processing algorithms.

Conclusion

While SmartIRT modules offer affordability and portability, their performance varies significantly. Temporal stability emerges as a critical factor, with the Hikmicro module demonstrating leadership in this aspect. Careful consideration and validation are necessary when selecting and utilizing SmartIRT modules for medical applications.
