The passages discuss the mathematical underpinnings of computerized axial tomography (CAT or CT scans) [1]. Allan McLeod Cormack developed mathematical algorithms that could be used to create an image from X-ray data, and Godfrey Newbold Hounsfield designed the first operational CT scanner [1]. The fundamental mathematical problem behind CT scans is reconstructing a function if the values of its integral along all possible cross-sections are known, which is an example of an inverse problem studied by Johann Radon [2].
The passages highlight a significant practical implication: the development of CT scans, which has led to a dramatic increase in their use, from about 3 million scans annually in the United States in 1980 to over 67 million [1]. However, the passages do not detail other practical implications beyond the application in medical imaging through CT scans.

From the book
Title: The Mathematics of Medical Imaging by Timothy G. Feeman Description: In 1979, the Nobel Prize for Medicine and Physiology was awarded jointly to Allan McLeod Cormack and Godfrey Newbold Houns eld, the two pioneering scienti- engineers primarily responsible for the development, in the 1960s and early 1970s, of computerized axial tomography, popularly known as the CAT or CT scan. In his papers [13], Cormack, then a Professor at Tufts University, in Massachusetts, dev- oped certain mathematical algorithms that, he envisioned, could be used to create an image from X-ray data.

nd this procedure is essentially mathematical: If we know the values of the integral of a two- or three-dimensional fu- tion along all possible cross-sections, then how can we reconstruct the function itself? This particular example of what is known as an inverse problem was studied by Johann Radon, an Austrian mathematician, in the early part of the twentieth century.
