Perspective on the First 10 Years of the CT Scanner Industry

High resolution tomographic imaging of the alveolar region of the mammalian lung

“…This approach blurred structures lying out of the selected region of interest. But this advance over conventional radiographies was insufficient to make two-dimensional tomographic images a useful diagnostic tool [41].…”

Commentary on “Computed Tomography of the Body: Initial Clinical Trial with the EMI Prototype” and “Computed Tomography of the Body: Early Trends in Application and Accuracy of the Method”

“…Who might have expected then that CT would become responsible for about two thirds of medical radiation exposure [6]? EMI had originally projected a worldwide need for about 25 machines [1]. However, interestingly, along with the recognized benefits of this early validation of the clinical value of CT technology, some of the potential abuses were already being seen: "Situations are developing in which nonradiologic physicians are installing CT devices in their offices" [5].…”

“…It is lost to history whether these words helped to inspire the executives of Electric and Musical Industries (EMI) to direct surplus earnings from Beatles record sales toward revolutionizing the way radiologists "look through you." Regardless, EMI's financial support of the research of Godfrey N. Hounsfield (who had been an EMI employee since 1951), made possible by the Beatles, did lead to the first prototype CT scanner in 1967 and the first clinical "EMI scanner" in 1971 [1].…”

Review of Gallium-68 PSMA PET/CT Imaging in the Management of Prostate Cancer

“…Within 4 months of Roentgen’s discovery of X-rays in Germany in November 1895, Walter Drowley Filmer, an amateur scientist and electrician, used X-rays to localize a foreign object within a patient in Newcastle, New South Wales [ 4 ]. The introduction of CT scans took a little longer with Australia waiting 2 years from the installation of the first whole body CT scanner at Northwick Park Hospital in London in 1975 [ 5 ] to the installation of the first CT scanner in a Sutherland hospital in Sydney [ 6 ]. The first human magnetic resonance imaging (MRI) scan was performed in 1977 and in 1986 the first MRI was installed in the private sector, in Sydney [ 7 ].…”
