Swallowable camera pill provides imaging of esophageal lining

The video tutorial explains the process of capturing cross-sectional and 3D images of the upper gastrointestinal tract using a pill-sized device. The patient swallows the device, which is then moved through the esophagus to capture images. The device employs a laser to scan its surroundings, and the imaging equipment tracks the laser's reflectance. This process results in a 3D image and a reconstruction of the esophagus.
