A group of Austrian and German researchers are using OCT — an optical method roughly analogous to ultrasound — to look at how blood vessels differ among different skin conditions. The most common type of skin cancer (basal cell carcinoma) has a distinctive blood supply. This is still very preliminary work, and it’s specifically related to skin cancer.
Still, pretty neat. Read about it in my story at Optics & Photonics News:
– Spotting Cancer By Its Blood Supply.
