Abstract
Perfusion angiography combined with photoplethysmography imaging for peripheral vascular disease assessment A device () and method for performing perfusion imaging receive image sequences that are acquired simultaneously by an X-ray imaging apparatus () and by a photoplethysmography imaging apparatus (). When temporally aligned, changes in the perfusion states of a perfused organic tissue over time are extracted from the two image sequences and an image is generated for display on a display unit () which indicates the changes in the perfusion states at various locations of the perfused organ tissue, thereby capturing both deep organ tissue and superficial organ tissue perfusion properties. A diminution in an image signal strength in the photoplethysmography images caused by a passage of a bolus comprising a previously administered contrast agent () can be used to align the two concurrently acquired image sequences in time.
