Diagnosis of dysplasia in Barrett's oesophagus with in-situ elastic-scattering spectroscopy

Barrett's oesophagus is a metaplstic condition resulting from acid reflux that affects a small but significant percentage of the population. Detection of pre-malignant changes within this tissue may allow for preemptive treatment against oesophageal cancer. Optical biopsies using elastic scattering spectroscopy are being investigated as a possible in-situ diagnostic technique.
