Godfrey Hounsfield

In the early 1900s an Italian radiologist by the name of Alessandro Vallebona was the first one to propose a method to represent a single slice of the body on radiologic film developed on principles of projective geometry (Li, 2013). Throughout the 1900s it was used for practical research etc , but in 1971 in the United Kingdom engineer Sir Godrey Hounsfield and Africa-born physicist Alan Cormack invented the first commercially viable CT scanner in the world. Interesting fact is that they never actually met until their Nobel peace prizes were awarded to them. The very scanner took about 2 hours to produce 1 slice, but nowadays 4 slices can be produced in less than 1 second due to the amazing improvements in speed, quality, technology and comfort. Through the great technological and research improvements high quality images are able to be produced at the lowest possible radiation dose which helps patients avoid other related diseases brought on by radiation exposure and helps retain cancer risk to their lowest possibility. Cormack and Hounsfield were awarded a Nobel peace prize in 1979 for their contributions to medicine and science (LA times,…

II’s order because they felt betrayed by Alexius I. In 1099, after the crusaders celebrated their victory, they concluded that they had to repopulate the city, appoint a rule, and expand their territory to keep Jerusalem under Christian rule. However, the Christians establishment of the Latin kingdom of Jerusalem emerged out of Muslim disunity and alliances between Muslims and Franks. The leaders of the Crusade immediately assigned a ruler to protect and govern Jerusalem. Initially, the…

mechanism by which the artist turns the simple into the phenomenal, the static into the dynamic, the two dimensional into the three dimensional, and can be looked at through the lens of Gestalt psychology--the concept that the work as a whole is different from the sum of its individual parts. Based on the current, Western perception of progress, society can be broken into collections of nations and regions that form pseudo classes or castes--the most distinct being the Emerging Countries and the…

Humans, animals, technology, and this planet, are constantly changing and adapting to their surroundings. Life goes on despite the extent of the change, just as the train represents time moving non stop past the tree, that represents life in the movie. The film Powaqqatsi by Godfrey Reggio, displays great change over time to the new industry that erodes the traditional ways of several countries. Transitioning from a slow motion opening scene to a rapid ending pace, the film uses facial…

bones or internal organs that existed in other planes” (http://theinstitute.ieee.org/technology-focus/technology-history/a-brief-history-of-medical-scanning-technology). From this concept the first tomogram of a single plane of a heart was accomplished in 1914 by a Polish doctor named Karol Mayer. From there in 1960, William Oldendorf patented “an electronically based device that could capture image slices continuously through a solid object.” This device lacked the “computational power to turn…

cancer, and check whether the cancer has recurred There are many more applications of CT Scan such as to check condition of trauma patients arriving after an accident, detection and analysis of cardiovascular disease, spinal problems, etc How does CT-scan work? Series of narrow X – Ray beams of varying intensity as the scanner moves through an arc The X-Ray detectors are able to see hundreds of different intensity X - Rays Data send to a computer Using image processing techniques the…
