1. A system for determining a probability of the existence of polyps in a gastrointestinal tract of a patient through capsule dynamics, comprising:
a capsule that can be swallowed by a patient; wherein the capsule comprises a controller, a transceiver and one or more sensors that track information of position and/or motion of the capsule within the patient and transmit the information;
a recorder comprising a transceiver and controller;
wherein the recorder is worn by the patient and receives transmissions of the information from the capsule;
wherein the system determines position or motion information of the capsule from the information received from the capsule, analyzes the position or motion information and determines a probability score representing the likelihood of the existence of polyps in the gastrointestinal tract of the patient; and
wherein the system comprises a display that is provided with a message to notify the patient of further actions to be performed in response to the determined probability score; and
wherein the information from the capsule is used to determine a time interval for traversing the gastrointestinal tract or specific organs within the gastrointestinal tract, and the probability score is based on the time interval.
