Conventional diagnostic modalities for assessing arterial circulation or tissue perfusion include blood pressure measurement, ultrasound evaluation, and contrast-based angiographic assessment.An infrared thermal camera can detect infrared radiation energy from the trigon decal human body, which generates a thermographic image to allow tissue perfusion analysis.We describe a smartphone-based miniature thermal imaging system that can be used as an adjunctive imaging modality to assess tissue perfusion.This smartphone-based camera device is noninvasive, simple to use, and cost-effective in assessing patients with lower extremity tissue perfusion.Assessment of patients with lower extremity arterial ischemia can be performed by a variety of diagnostic modalities, ruoan s?ilytysastia including ankle-brachial index, absolute systolic ankle or toe pressure, transcutaneous oximetry, arterial Doppler waveform, arterial duplex ultrasound, computed tomography scan, arterial angiography, and thermal imaging.
We herein describe a noninvasive imaging modality using smartphone-based infrared thermography.
