Gastric Contraction Imaging System Using a 3-D Endoscope

Abstract: This paper presents a gastric contraction imaging system for assessment of gastric motility using a 3-D endoscope. Gastrointestinal diseases are mainly based on morphological abnormalities. However, gastrointestinal symptoms are sometimes apparent without visible abnormalities. One of the major factors for these diseases is abnormal gastrointestinal motility. For assessment of gastric motility, a gastric motility imaging system is needed. To assess the dynamic motility of the stomach, the proposed system measu… Show more

“…Several advanced, preferably noninvasive and real-time, imaging technologies have been adopted to overcome this hurdle, but further progress is still required. Magnetic resonance (MR), contrast-enhanced MR, computed tomography (CT) and nuclear imaging, capsule endoscopy, 3D endoscope imaging, high-resolution electrical mapping, and electrogastrogram have been used to visualize the gut lumen (patho)-physiology and gain insight into the in vivo behavior of drug/formulation in preclinical species, healthy humans, and patients. Furthermore, systematic exploration of the capabilities of molecular dynamics (MD) simulations, synchrotron small-angle X-ray scattering, coherent anti-Stokes Raman spectroscopy, and surface plasmon resonance would promote understanding of membrane transport, drug-colloidal structures interactions, lipid imaging at the molecular level, drug or excipient release, disposition, and intracellular concentrations. ,,, Thus, a plethora of opportunities not only for GI imaging but also for the development of data analysis and in silico tools, which will be interacting or even be integrated into PBPK models, is foreseen.…”

“…This would allow more accurate resection of subsurface tumours or other features not easily visible by optical means. Furthermore, topological data may add diagnostic value by detecting features such as flat polyps, or quantifying the function of the gut through its motility 5 .…”
