To simulate the hemodynamic effects in the feet in response to a thigh cuff occlusion, we have developed a multi-compartmental model in which the circulatory system for the leg is represented by its electrical equivalents. Dynamic vascular optical to

Objective Vascular optical tomographic imaging (VOTI) is a novel imaging modality that is capable of detecting hemoglobin concentrations in tissue. VOTI is non-invasive, non-ionizing and does not require contrast injection. This technology was applie

Peripheral Arterial Disease (PAD) is caused by a reduction of the internal diameters of the arteries in the upper or lower extremities mainly due to atherosclerosis. If not treated, its worsening may led to a complete occlusion, causing the death of

Dynamic optical tomographic imaging has shown promise in diagnosing and monitoring peripheral arterial disease (PAD), which affects 8 to 12 million in the United States. PAD is the narrowing of the arteries that supply blood to the lower extremities.

We present dynamic diffuse optical tomography (DDOT) results from a 34-patient study for detecting peripheral arterial disease and patients with and without diabetes. DDOT achieved a sensitivity of 80% and a specificity of 70%.

We introduce here a temporally constrained image reconstruction method that enables fast dynamic tomographic imaging of the spatial distribution of tissue parameters (e.g., HbO2, Hb, StO2, etc). The proposed method decomposes the original time varyin

Peripheral Arterial Disease (PAD) is the narrowing of the functional area of the artery generally due to atherosclerosis. It affects between 8-12 million people in the United States and if untreated this can lead to ulceration, gangrene and ultimatel
