Abstract: 

Medical imaging is an essential diagnostic tool in medical field and one of the main key issues in health care. Medical imaging is done through invasive, minimally invasive and non-invasive techniques. Medical imaging through non-invasive technique is widely used to view the internal organs of human body. Among the various non-invasive medical imaging modalities, ultrasound medical imaging and magnetic resonance imaging modalities are used for imaging the internal organs as these imaging modalities are safe, risk free, no harmful radiation exposures and do not cause any damage to tissues of the human body. Biomedical image processing has been an interdisciplinary research field which interests many experts and researchers from various fields. The principal objective of this review article is to discuss on the advantages of using magnetic resonance imaging over ultrasound imaging modality, provide an introduction to basic principles and instrumentation of magnetic resonance imaging medical system, generation of magnetic resonance signals and how to process and analyze a significant volume of images for getting high quality anatomical information for diagnosing abnormalities of internal organs within human body thereby to promote interests for further study and research in medical imaging and medical image processing
