CAT Scans

Introduction Figure 1. Computerised Axial Tomography Scans, or mold scans, ar now a frequently used light beam in the medical industry and are based on the candid principle of an roentgenogram. CAT scans take the brain of naturalized roentgenogram imagining to a newfangled level. Instead of just finding an learn of the outline of bones and organs as an roentgenogram would do, CAT scans show us a 3-dimensional representation. This enables doctors to examine the bole in narrow slices at a time to pin-point specific areas. A CAT scan machine looks like a titan doughnut tipped on its side as shown in Figure 1. The patient lies down on the platform, which and then slowly moves through the hole in the machine. The X-ray thermionic tube is attach on a movable noise slightly the edges of the hole. The ring also supports an array of X-ray detectors directly reverse the X-ray tube. This allows scans to be taken from hundreds of different angles. A negatronic comput er then takes all this information and puts it together to create a 3D image of the body. The X-ray was commencement exercise discover by German physicist Wilhelm radius. He first made the baring in 1895 when experimenting with electron rays in gas discharge tubes. As he was experimenting he observed that a light top in his science laboratory would glow only when the electron beam was turned on.

fluorescent material glows in the front line of electromagnetic radiation; however, universal gas constant thought that in finish his tube with cardboard, the radiation would not escape and react with the fluorescent screen. Roentgen then experimented by putting various objects! in the way, but, the screen still glowed. ultimately he put his impart between the electron beam and the fluorescent screen and he saw a silhouette of the bones in his hand. Roentgen later received the first Nobel Prize in physics in 1901 for his discovery of this new kind of ray. CAT scanners were veritable much later, in the yr 1972 by Sir Godfrey Hounsfield. The English galvanizing engineer came up with the idea that one...If you want to get a full essay, order it on our website: BestEssayCheap.com
