A. Withem Konrad Röntgen
B. Bloch and Purcell
C. Hounsfield
D. Gopal Samudram

Answer 1

Hint: Computed Tomography (CT) imaging is also known as "CAT scanning" (Computed Axial Tomography).
Tomography is from the Greek word "tomos" meaning "slice" or "section" and "graphia" meaning "describing.

Complete answer: CT was invented in 1972 by British engineer Godfrey Hounsfield of EMI Laboratories, England and by South Africa-born physicist Allan Cormack of Tufts University, Massachusetts.
Hounsfield and Cormack were later awarded the Nobel Peace Prize for their contributions to medicine and science.
CT scans can detect bone and joint diseases, like complex bone fractures and tumors.
If you have a condition like cancer, heart disease, emphysema, or liver masses, CT scans can find it or help doctors see any changes.
They show internal injuries and bleeding, such as those caused by a car accident and other infections.

Additional information: The original systems were dedicated to head imaging only, but "whole body" systems with larger patient openings became available in 1976.
CT scans became widely available by about 1980.
The first CT scanner developed by Hounsfield in his lab at EMI took several hours to acquire the raw data for a single scan or "slice" and took days to reconstruct a single image from this raw data. Whereas the recent CT scans can acquire data quite easily.

So, the answer is C. Hounsfield

Note: CT scan replaced the more invasive pneumoencephalography for imaging of the brain, as well as most applications of focal plane tomography.
