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, especially to identify malignant cells. It uses pattern recognition and image processing technology originally developed in DRDO. 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 was initially developed was specifically meant to detect uterine cervical cancer. After validation at reputed institutions, the system was used for mass screening of rural and tribal women in the rural districts of erstwhile Andhra Pradesh for cervical cancer. |
