Medical imaging is a technique and process that creates a visual representation of the body and the visual presentation of certain organs and tissue functions for clinical analysis and medical intervention. We consider detecting different physical signals from the patient's body and converting them into medical images. In fact, these signals come from a certain process. Transmission of radiography through the body in X-ray projection and fluoroscopy, mammography, and computed tomography. Ultrasound is reflected in the body to be used for ultrasound. The precession of a spin system in a large magnetic field and its application in magnetic resonance imaging¹. These radiographic imaging methods in this article are x-ray radiography, mammography, fluoroscopy, computed tomography, magnetic resonance imaging, and ultrasound imaging. Medical imaging technology is creating an internal visual representation of the body. This is a non-invasive method of observation without opening the body by surgery^1,2. It is used for the clinical analysis and the diagnosis and auxiliary treatment of different medical conditions. Medical imaging technology has also established normal anatomical and physiological databases, making it possible to identify abnormalities. There are many diagnostic imaging technologies, and they also have risks and benefits. In this article, the application of electromagnetic waves and radio frequency waves in different modalities such as general X-ray photography, fluoroscopy, mammography, computed tomography (CT), magnetic resonance imaging (MRI) and ultrasound will be our investigation. Provide utility and challenge. The opinion of. This article presents a comparative study between the different medical imaging modes and their technologies. The conceptual advantages, risks and applications of this technology will be presented with the details of the modes. As of 2010, up to 5 billion medical studies have been conducted worldwide. This article presents comparative studies between different medical imaging modalities, and presents the concepts, risks, benefits, and the applications of these technologies in detail. Relevant technologies are: Radiography, Mammography, Fluoroscopy, Computed Tomography, Magnetic Resonance Imaging, and Ultrasound. Comparisons between these techniques in terms of image quality (spatial resolution and contrast), safety (effects of ionizing radiation and heating effects of radiation on the body), and System availability (real time and cost information) was presented. Discussions suggest that none of these techniques can be trusted exclusively in medical applications.
