Abstract
An apparatus and method for medical practitioners to detect the presence of abnormal cells including cancerous and pre-cancerous cells by using a transport capsule containing an imaging apparatus including UV sources and fluorescence detectors for obtaining images and fluorescence data of biological cells and tissue. The method includes the steps of scanning biological tissue using an ultra-violet (UV) source to obtain fluorescence data, transferring fluorescence data and/or images using a radio frequency (RF) or other suitable means to a personal computer (PC) system, analyzing the image and/or fluorescence data in the PC, identifying -tissues with precancerous and cancerous cells, and optionally determining their precise location, and assessing the accuracy of the calculated fluoroscopic images.
