Endoscopes Utilizing Tunable Microlenses

Endoscopes are important medical instruments that produce images of the interior surfaces of cavities in human bodies, for example the gastrointestinal (GI) tract including the esophagus, stomach, colon, and part of the small bowel joint spaces abdominal cavity thorax and other structures. In recent years, through technical improvements like wireless capsule endoscopy [32] and robotic surgery [33], minimally invasive surgery has become a common treatment. [Pg.171]
