Abstract
An apparatus and a method for detecting clinically-relevant features of the gastrointestinal (GI) tract of a subject are disclosed. The apparatus includes a capsule to be swallowed by a subject and passing through the GI tract of the subject, a capsule housing, a radiation source emitting radiation, a rotatable collimator configured to rotate with respect to the housing and to collimate the radiation emitted by the radiation source, and a radiation detector configured to detect particles, such as photons, gamma radiation, beta radiation and electrons photons generated responsive to the emitted radiation. The apparatus also includes a control unit configured to analyze data regarding the photons. Movement of the capsule in the GI tract can be detected from a comparison between at least two images acquired with the apparatus. The radiation source, radiation detector and control unit may advantageously be integrated inside a single housing.
