Objective: Biomedical signal/image processing and the related imaging modalities is a very vast growing and upcoming field. This paper presents the promising image processing techniques used in medical field. Methods: Application of image processing techniques has played a vital role in assisting the surgeons and physicians in diagnosing the diseases and performing the surgeries for the patients. Clinical medical devices has erupted through combination of hardware and image processing techniques which has a giant leap in medical field. Results: Biomedical signals fetching, image formation, processing of image, and image display for medical/clinical diagnosis based on extracted features from the signal (1D), images (2D) and Video (3D). Image processing has proved its significance in medical analysis and health care. Conclusion: The imaging modalities play a vital role in acquisition of signals and images from human body which involves invasive and non-invasive methods. © RJPT All right reserved.
