Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues . Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease.
A radiologist interpreting magnetic resonance imaging Dr. Macintyre's X-Ray Film (1896). Radiology (/ ˌ r eɪ d ɪ ˈ ɒ l ə dʒ i / rey-dee-ol-uh-jee) is the medical specialty that uses medical imaging to diagnose diseases and guide treatment within the bodies of humans and other animals.
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object.Applications of radiography include medical ("diagnostic" radiography and "therapeutic radiography") and industrial radiography.
Interventional radiology (IR) is a medical specialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices.
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.
Taking an X-ray image with early Crookes tube apparatus, late 1800s.. For the first three decades of medical imaging's existence (1897 to the 1930s), there was no standardized differentiation between the roles that we now differentiate as radiologic technologist (a technician in an allied health profession who obtains the images) versus radiologist (a physician who interprets them).
Medical imaging. The measure is used in radiology to quantify the quality of acquired images. It is a difficult quantity to define because it depends on the human ...
Tomography is imaging by sections or sectioning that uses any kind of penetrating wave. The method is used in radiology, archaeology, biology, atmospheric science, geophysics, oceanography, plasma physics, materials science, cosmochemistry, astrophysics, quantum information, and other areas of science.
