One of our main areas of expertise lies in a type of examination of the gastrointestinal tract that uses a capsule endoscope containing a light source, one or two cameras, a transmitter and a battery. This capsule is either swallowed by the patient or is positioned inside the esophagus, stomach or small bowel during a gastroscopy procedure. Capsule endoscopy, which is used to detect polyps or other GI changes, is easily performed while the patient is awake. This method has a good detection rate for GI changes but cannot be used for the removal of polyps or other surgical procedures.
Images are transmitted to a decoder at a rate of one frame per second and can be viewed in “real time”. In most cases, however, the images obtained are evaluated after completion of the procedure.
