Diabetes complication arises mostly in the foot and worst scenarios leading to amputation. The aim is to do a 3-dimensional reconstruction of foot vessels during cuff inflation and deflation through a signal collection using remote NIRS having high spatial resolution and low sensitivity. The images could be of use for non-ionizing and non-invasive assessment of blood flow.

The comparison of temporal features was consistent. At 0 mm Hg, there is greater blood flow which resulted in greater absorption of optical light, therefore, lesser NIR intensity detected. However, better vessel structures were reconstructed in lesser blood flow with higher scattering and less absorption.
The processing of signals allowed the extraction of spatiotemporal features and 3D image reconstruction. These images could be of use as biomedical evidence in the assessment of foot vessels that could improve patients’ quality of life.
