The Fundamentals of Biomedical Image Processing

Various Modalities Of Medical Imaging

There are number of medical imaging modalities used for different purposes and applications such as ultrasound imaging, mammographic imaging etc. There have been several improvements over the technologies and imaging methods including modern image acquisition systems and sensors with which the medical imaging systems are built. The most commonly used technique for capturing breast X- ray images is Mammography. Although High quality scanners are nowa day’s avalaible but improper radiation still poses problems sometimes and hence, the radiation risk is expected to be negligible (Guy, 2005).

Computer aided diagnosis systems used a digital mammographic image as input image to be analysed from a conventional film mammogram and masses, calcifications or other abnormal areas are detected. The Anomalies present may indicate the presence of cancer. The accuracy of breast cancer detection has been enhanced to a significant level with the advent digital mammographic techniques.
