Philips said it will team with Academic Medical Center in Amsterdam to test the technique as part of a European multi-center study. They want to develop technology that analyzes perfusion angiography images and also produces quantitative information on blood flow in the capillaries of the foot.
Perfusion angiography is a new X-ray imaging technology that relies on the high temporal and spatial resolution of X-ray angiographic images. Philips said it’s developed software that assesses subtle physiological changes in perfusion levels.
Researchers want to improve on the existing standard of care, which relies on image-guided, minimally invasive treatments including angioplasty to reopen major blood vessels in the feet to restore blood flow. The process involves live X-rays and the use of a catheter inserted into a blood vessel in the leg and navigated to the foot in order to use a balloon or stent to restore blood flow.
Philips said that imaging is lacking, however, because it doesn’t give clinicians a good look at micro-circulation function. The Dutch conglomerate said its new technology would allow for the more detailed imaging in order to better measure the problem and affects of treatment.
"As a new instrument for image-guided therapy, perfusion angiography could usher in a new age of precision personalized treatment for diabetic patients that suffer from severe foot complications," Ronald Tabaksblat, business leader of Philips’ image guided therapy systems division, said in prepared remarks.
