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.

Perfusion angiography combined with photoplethysmography imaging for peripheral vascular disease assessment

The application relates to the problem of navigating a surgical instrument (at) towards a region-of-interest (at) in endoscopic surgery when an image () provided by the endoscope is obscured at least partly by obscuring matter (at), wherein the obscuring matter is a leaking body fluid, debris or smoke caused by ablation. To address this problem, a computer-implemented method is proposed, wherein, upon detecting that the image from the endoscope is at least partly obscured, a second image is determined based on a sequence of historic images and based on the current position and orientation of the endoscope. Furthermore, a virtual image () is generated based on the determined second image.
