A survey of small bowel modelling and its applications for capsule endoscopy

The small intestine, an anatomical site previously considered inaccessible to clinicians due its diameter and length, is the part of gastrointestinal tract between stomach colon. Since introduction into clinical practice two decades ago, capsule endoscopy has become established as primary modality for examining surface lining intestine. Today, researchers continue develop ground-breaking technologies novel miniature devices aiming tissue biopsy, drug delivery therapy. purpose this paper provide engineers in area a comprehensive review progress understanding anatomy physiology intestine how was translated virtual physical test platforms assessing performance these intestinal devices. This will cover both theoretical practical studies on motor activities work mathematical modelling experimental investigation endoscope In end, requirements improving current are drawn, expectations future research field provided.
