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 ( physiology ). Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease.
Physically, the robot is very lithe, moving around to scan its environment for targets, and jumping around almost like a ballet dancer when attacking. Its face is smooth with no visible eyes. According to the Eighth Doctor Adventures novel The Eight Doctors by Terrance Dicks , the robots were built by an ancient race, older than the Time Lords ...
Image from an active millimeter wave body scanner. A full-body scanner is a device that detects objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact. Unlike metal detectors, full-body scanners can detect non-metal objects, which became an increasing concern after ...
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 ...
Kalanithi's life takes an unexpected turn when, after weeks of health problems, it is confirmed that he has lung cancer. Images obtained from a CT scan show organ systems compromised by cancer, causing him and his wife great sadness. Searching for the best experts in the field of oncology, Kalanithi begins treatment with a doctor named Emma ...
Modern 3 tesla clinical MRI scanner. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and ...
These scans are non-invasive, and generate a 3D mapping which differentiates between the ink and the paper. The virtual unwrapping process is independent of which type of volumetric scan is used, which allows scientists to test out different scanning methods to find which distinguishes ink from paper best and which easily accommodates scanning ...
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") and industrial radiography. Similar techniques are used in airport security, (where "body scanners ...
