CYTOSCAN SYSTEM
This is a personal computer based system capable of acquiring and analyzing the image of a cell with a view to detect and classify cell abnormalities. The system was found very useful for mass screening of people for cancer. It uses pattern recognition technology originally developed by DRDO for life support systems and also image processing technology. The hardware consists of a PC/AT, microscope, CCD camera and frame grabber. The multi module software consists of an acquisition module, display module, mouse based delineation module to mark the cell to be analysed, module to measure geometrical and textural parameters and an expert system to detect and classify cell abnormalities. The software that has been developed is specifically meant to detect uterine cervical cancer. Statistical programs to analyse large volumes of cell data have also been developed. The technology was completely validated at Kidwai Memorial Institute of Oncology, Bangalore and Nizams/ Institute of Medical Sciences, Hyderabad. The system was used under project TULASI, in the rural districts for screening rural and tribal women for cervical cancer. |
