3-D Medical Scanner Anthony D’Onofrio BME 281 Section 2, Tuesdays 11/27/12

Currently Primary care physicians currently rely on instruments that are essentially magnifying glasses to check for ear and eye infections They only allow doctors to check for inflammation of the ears and eyes

New 3-D Device Handheld scanner – University of Illinois at Urbana-Champaign – Image all the sites they examine and more Bacterial colonies in the middle ear in 3-D Monitor the thickness and health of patients' retinas. Relies on optical coherence tomography (OCT) – Visualization technology – Similar to ultrasound imaging Uses light instead of sound to produce the images.

Basic Components The scanners include three basic components Near-infrared light source and OCT system Video camera Used to relay real-time images of surface features and scan locations Microelectromechanical (MEMS) based scanner to direct the light Near-infrared wavelengths of light penetrate deeper into human tissues than other wavelengths By measuring the time it takes the light to bounce back from these tissues, computer algorithms build a picture of that tissue

Future Faster more accurate scans Give doctors a way to monitor conditions, and possibly make more efficient and accurate referrals to specialists. Diabetic patients also benefit. About 40 to 45 percent of diabetics develop leaky blood vessels in their retinas Retinopathy, Lead to thickening of the retina, blurry vision, and eventually blindness. Allow doctors to monitor the health of the retina, potentially catching retinopathy in its early stages. Changes in the eye could help doctors diagnose diabetes
