CAT Scans

Introduction

Figure 1.

Computerised Axial Tomography Scans, or roam scans, ar now a frequently used tool in the medical industry and are based on the candid principle of an roentgenogram. CAT scans take the brain of conventional roentgenogram imagining to a newfangled level. Instead of just finding an learn of the outline of bones and organs as an X-ray would do, CAT scans show us a 3-dimensional representation. This enables doctors to examine the body 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 thusly slowly moves through the hole in the machine. The X-ray tube is attach on a movable noise around the edges of the hole. The ring also supports an array of X-ray detectors directly opposite the X-ray tube. This allows scans to be taken from hundreds of different angles. A computer then takes all this information and puts it together to create a 3D image of the body.

The X-ray was commencement exercise discovered by German physicist Wilhelm radius. He first made the discovery in 1895 when experimenting with electron rays in gas discharge tubes. As he was experimenting he observed that a fluorescent screen in his science laboratory would glow only when the electron beam was turned on.



fluorescent material glows in the presence of electromagnetic radiation; however, Roentgen thought that in covering 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 hand 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 developed much later, in the yr 1972 by Sir Godfrey Hounsfield. The English electrical engineer came up with the idea that one...If you want to get a full essay, order it on our website: Orderessay
