FDA Clears Olympus Endoscope Series
FDA has given 510(k) clearance to the Olympus EZ1500 series endoscopes that the company says feature extended depth of field (EDOF) technology. A company statement says the series’ gastroscope and colonoscope “represent Olympus’ most advanced imaging and latest innovation as part of the EVIS X1 endoscopy system. By allowing physicians to obtain sharp images, EDOF technology allows an entire lesion to be kept in focus and may aid in detection as endoscopists inspect the mucosal lining of the GI tract.”
Olympus says EDOF technology creates an image in total focus by using two prisms to split the light entering the endoscope lens into two separate beams with near- and far-focused images. The beams are then projected simultaneously onto an image sensor, combining them into one image with a wide depth of field.
