Recent Progress in Medical Imaging Technology

摘要

Medical imaging is the general name given to the methodology in which a biological object's structure or function, which is usually invisible, is visualized by using physical media such as X-rays for the diagnosis and treatment of diseases. The method is divided into ultrasonic imaging, magnetic resonance imaging, nuclear medical imaging, X-ray imaging, and the like, according to the physical media employed. These modalities have their own features and have been used to compete with and complement each other, offering indispensable techniques for medical care. Medical imaging is supported by highly developed engineering technologies, and the medical and engineering technologies in combination are referred to as medical imaging technology. This paper presents a survey of recent developments in medical imaging technology, focusing on magnetic resonance imaging, nuclear medical imaging, and X-ray imaging.
