In this paper, a variety of medical imaging systems including Ultrasonography, MRI, Bone Densitometry, Optical Coherence Tomography, Arthrography, etc. are reviewed and their advantages and disadvantages are also described. In addition to these methods, new techniques in medical imaging such as Shear Wave Elastography and Ultrashort Echo Time are also being reviewed. One of the most important of these methods is radiology imaging. Radiology is one of a variety of methods for imaging various parts of the body. Basically, the first assessment of the patient is radiology. Radiology is a non-invasive and rapid method for diagnosis. The basis of this method is the ionizer radiation rays. Radiology medicine is divided into two parts: diagnostic and therapeutic. Radiology medicine based on the energy used is divided into two types: radiology and nuclear medicine. The basis for the function of radiology is X-rays and the basis for the performance of nuclear medicine is radioactive material. Radiology is more dangerous than nuclear medicine, and is not suitable for pregnant women and children. But radiology is more accurate and faster than other methods. In addition to its advantages, this method also includes dangers for the human body. Wilhelm Röntgen was the first scientist to discover X-rays and record the first radiology image. This paper describes the components of a radiology device, including a X-ray tube, a collimator, a detector, and so on.
