The first computed tomography (CT) system capable of producing images of any part of the human body without the need for a cumbersome "water tank" was the Automatic Computerized Transverse Axial (ACTA) scanner, designed by Dr. Robert S. Ledley, DDS, at Georgetown University. This revolutionary machine was equipped with 30 photomultiplier tubes ...
CT scan. A computed tomography scan(CT scan; formerly called computed axial tomography scanor CAT scan) is a medical imagingtechnique used to obtain detailed internal images of the body.[2] The personnel that perform CT scans are called radiographersor radiology technologists.
Quantitative computed tomography ( QCT) is a medical technique that measures bone mineral density (BMD) using a standard X-ray computed tomography (CT) scanner with a calibration standard to convert Hounsfield units (HU) of the CT image to bone mineral density values. [ 1] Quantitative CT scans are primarily used to evaluate bone mineral ...
Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used for angiography —the visualization of arteries and veins —throughout the human body. Using contrast injected into the blood vessels, images are created to look for blockages, aneurysms (dilations of walls), dissections (tearing of ...

The first PET-CT systems were constructed by David Townsend (at the University of Geneva) and Ronald Nutt (at CPS Innovations in Knoxville, TN) with help from colleagues. [4] The first PET-CT prototype for clinical evaluation was funded by the NCI and installed at the University of Pittsburgh Medical Center in 1998. The first commercial system ...
Cone Beam CT scanner. MeSH. D054894. Cone beam computed tomography (or CBCT, also referred to as C-arm CT, cone beam volume CT, flat panel CT or Digital Volume Tomography (DVT)) is a medical imaging technique consisting of X-ray computed tomography where the X-rays are divergent, forming a cone.
