<unk>  requires a number of different preparatory procedures to ensure clear images are taken of a patient's gastrointestinal tract for an accurate diagnosis of disease. There are various types of<unk> s, but for a generalized description, one can assume the most common setup requires the<unk> , sensor array, storage unit, and computer system being used. First, a patient will need to have the sensor array placed on their abdomen with a recording unit worn as a belt. The patient may be asked to stay at the hospital or return home depending on the start time. Next, the pill must be swallowed by the patient. After approximately 8 hours the sensor array can be removed and returned to a physician. The<unk>  will be excreted through regular bowel movements. During the procedure, there are a number of different policies to follow. A patient should only drink clear liquids for the first two hours after swallowing the pill and may eat after 4 hours. MRI studies, ham radios, metal detectors, and strenuous physical activity should all be avoided. Additionally, all external equipment must be kept dry.
