Question

CT scanning has been developed by:
a. Roentgen
b. Godfrey
c. Chardack
d. Lennac

Answer 1

One can say that a medical imaging technique that uses computer-processed combinations of multiple X-ray measurements is called a CT scan. In general, it is made to allow the user to see inside the body without cutting. It is said that the CT scan is used to generate the images which were transverse (axial) anatomical planes, perpendicular to the long axis of the body at the initial stage. However, modern scanners allow the examined data to be reformatted as images in other planes.

Complete answer:
In the year of 1972 the British engineer Godfrey Hounsfield of EMI Laboratories, England, and South Africa born physicist Allan Cormack of Tufts University, Massachusetts together introduced the CT scan. Both the Hounsfield and Cormack have bestowed the Nobel Peace Prize for their charities to medicine and science.

The world's first pacemaker was invented by the scientists Chardack and Greatbatch. An acoustic medical device for auscultation, or listening to internal sounds of an animal or human is called a stethoscope. It was invented by Lennac. A vacuum tube that adapts electric input power into X-rays is called an X-ray tube. It is invented by Roentgen.

Hence, the correct answer is option (B).

Note: We know that the CT scanner has great importance in the present day. Over the last two decades, the usage of CT scans has increased dramatically. A CT scan is taken from different angles to produce tomographic images of a body. It is estimated that in the year of 2007, over 72 million scans were performed in the United States. Also, the count has increased to 80 million in 2015.
