Medical imaging refers to the visualization of the body parts, organs, tissues or cells for clinical diagnosis, disease monitoring and treatment. The imaging techniques used in medical devices include variety of modern equipments in the field of optical imaging, nuclear imaging, radiology and other image-guided intervention. The radiological method renders anatomical and physiological of the human body at a very high spatial and temporal resolution. The radiology discipline covers methods such as ultrasound, CT scan, X-ray, MRI and other similar devices. Whereas, the optical imaging techniques include devices such as optical coherence tomography (OCT), which helps in revealing abnormalities at cellular level with the help of optical tracers for specific tumor cells.
