Bio-imaging refers to tools and technologies used to create structural or functional images of living objects or systems. Medical imaging in bio-imaging involves use of techniques and processes to create images of the anatomical areas and tissues of the human body to the molecular level. This helps in diagnosis and examination of disease and also helps to establish database of normal anatomy and physiology for future study. On the other hand, molecular biology in bio-imaging is related to the spatial and temporal arrangement of biological macromolecules. Bio-imaging incorporates radiology which involves various imaging technologies of X-ray radiography, medical ultrasonography or ultrasound, magnetic resonance imaging, elastography, endoscopy, thermography, tactile imaging, medical photography and nuclear medicine functional imaging techniques such as positron emission tomography. Medical imaging is considered as a set of techniques that produce images of internal structures of the body non-invasively. Bio-imaging aims to improve human health with the use of imaging techniques to advance diagnosis, prevention and treatment of human diseases.
