Damadian was the first to perform a full-body scan of a human being in 1977 to diagnose cancer. Damadian invented an apparatus and method to use NMR safely and accurately to scan the human body, a method now well known as magnetic resonance imaging (MRI). [5] Damadian received several prizes.
Fluid-attenuated inversion recovery (FLAIR) is a magnetic resonance imaging sequence with an inversion recovery set to null fluids. For example, it can be used in brain imaging to suppress cerebrospinal fluid (CSF) effects on the image, so as to bring out the periventricular hyperintense lesions, such as multiple sclerosis (MS) plaques.

The idea for the PET scan was originally proposed by William Sweet in the 1950s, but the first full-body PET scanner wasn't actually developed until 1974 by Michael Phelp. [ 9 ] Similarly, the single-photon emission computed tomography scan, or SPECT scan, also works by scanning a tracer within the patient.
[15] [16] [30] Damadian claims to have invented the MRI. [31] The U.S. National Science Foundation notes "The patent included the idea of using NMR to 'scan' the human body to locate cancerous tissue." [32] However, it did not describe a method for generating pictures from such a scan or precisely how such a scan might be done. [33] [34]
"Reynolds Rocket" pen was introduced at Gimbel’s department store in New York City, selling $100,000 worth of pens on the first day. [2] Demand in 1945 was running 30,000 pens per day, making it America's #1 ballpoint pen. [3] However, within three years the price of the pen went from $12.50 to 50¢.
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 various airliner bombing attempts in the 2000s.
Such generic body outlines can be made by Automatic Target Recognition (ATR) software. As of June 1, 2013, all back-scatter full body scanners were removed from use at U.S. airports, because they could not comply with TSA's software requirements. Millimeter-wave full body scanners utilize ATR, and are compliant with TSA software requirements. [12]
A full-body scan is a scan of the patient's entire body as part of the diagnosis or treatment of illnesses. If computed tomography ( CAT ) scan technology is used, it is known as a full-body CT scan , though many medical imaging technologies can perform full-body scans.
