Medical Imaging and Diagnosis

  Medical imaging is the technique and process of creating visual representations of the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology). Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease. Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities. Although imaging of removed organs and tissues can be performed for medical reasons, such procedures are usually considered part of pathology instead of medical imaging.

Medical images are pictures of distributions of physical attributes captured by an image acquisition system. Most of today’s images are digital. They may be post processed for analysis by a computer-assisted method. Medical images come in one of two varieties: Projection images project a physical parameter in the lung disease in human body on a 2D image, while slice images produce a one-to-one mapping of the measured value. International radiology conferences explore the new technologies in medical images. Medical images may show anatomy including the pathological variation of anatomy if the measured value is related to it or physiology when the distribution of substances is traced. X-ray imaging, CT, Dynamic MRI, nuclear imaging, ultrasound imaging, and Cellular imaging is the study of living cells using time-lapse microscopy, photography. The discussion focuses on the relationship between the imaged physical entity and the information shown in the image, as well as on reconstruction methods and the resulting artifacts.
