An endoscopy involves examining the inside of a person's body. The procedure uses an endoscope.
An endoscope is a medical device consisting of a long, thin, flexible (or rigid) tube. It has a light and a video camera. It helps see the inside of the patient's body on a screen.
Olympus has recently launched the VISERA 4K UHD surgical endoscopy system in Europe. According to the company, this is one of the first integrated endoscopy systems on the market to deliver 4K resolution and Ultra HD video providing four times more image information than Full HD.
An endoscopy is often used to confirm a diagnosis when other medical devices, such as an MRI, X-ray, or CT scan are proved inappropriate.
