Compiled by 8/2011 Please
Radiography has numerous modality technologies that are worthy of comparison. Among the more interesting and frequently used are MRIs, CTs, and Mammograms.
Each of these modalities work in a distinctive way and, consequently, vary considerably in their application. The predecessor of CTs,
tomography and radon transform, were actually developed in the early 1900s respectively in Italy by radiologist Alessandro Vallebona and by Johann Radon. The technology produces a radiographic image of
a single slice of the subjects body. In the 1970s, however, the advent of minicomputers facilitated the use of a transverse axial scanning method that would come to be
known as CT. This technology was spearheaded into development by Godfrey Hounsfield and Allan McLeod Cormack. Through his work at Central Research Laboratories in the United Kingdom, Hounsfield
was able to produce the prototype of the first CT scanner that was commercially viable in terms of cost and availability (Richmond 329).
As is the case with most medical technology, CTs quickly progressed from that first prototype to much more complex and capable versions. CTs are now capable of scanning a
larger number of slices of the body in a much smaller period of time (Freiherr 126). Furthermore, there has been a radical improvement in resolution and image quality. High
