The 5G+VR (virtual reality) capsule gastrocamera medical system allows patients to receive remote medical diagnosis for gastrointestinal diseases such as gastric diseases without pain and without anesthesia, just by drinking one small capsule, with a diameter of 11 millimeters and a length of 27.5 millimeters. After the capsule has entered the stomach, two magnetic fields can control the movement of the capsule.
