Optical Polyp Testing for In Vivo Classification

When a suitable area of tissue is identified by the clinician during a patient's colonoscopy (e.g., a polyp), the imaging probe is inserted into the colonoscope so that it can view the tissue. Optical spectral reflectance and autofluorescence imaging is then performed to collect white light reflected by, and fluorescent light emitted from, the tissue. This is then analysed by hardware and software components in the external analysis unit.
