To aid speed up masking for spotting Melanoma , the most deadliest type of tegument cancer , dermatologists already utilize digital television camera with wide - angle lenses to capture image of a patient role ’s body . But to ensure there ’s enough result to soar upwards in near and visually study a specific area , researchers at Duke University have developed a 250 megapixel camerathat provides extremely detailed views of a patient ’s skin .
The usual access to creating a massive gigapixel image is to use a individual television camera to take multiple shot of a subject , and then digitally stitch all of the images together into one massive photo . But that attack is time consume , and would postulate a patient to stand still for longer than most people are unforced or able-bodied to .
So the investigator at Duke University took a different plan of attack . A single lens is point at a patient , and the image it produces is simultaneously photographed by 34 digital microcameras — sort of like photographing the Nox sky by pointing your camera at the eyepiece of a scope . The microcameras are all specifically arranged to help compensate for optical imperfectness produced by the big crystalline lens , while software mechanically bring forth a unmarried massive 250 megapixel image of a patient .
The camera can shoot an entire body up to six - and - a - half - foot tall , and before a dermatologist even has a fortune to examine the image , a computer can perform a preliminary check for signs of skin cancer and automatically flag areas of worry . And while the system of rules is n’t a replacement for a dermatoscope , an imaging cock already used by dermatologists for closer scrutiny , it is faster and the automatise feature article can serve speed up cancer masking and the figure of patients that can be processed .
