How was the CT scan made?
CAT scanners use X-ray technology to create three-dimensional images of the body’s internal structures. Images are obtained by rotating the x-ray generator and detectors around the patient. This information is fed into a computer, which reconstructs images of the body structures within its plane of focus.
What is a CT machine made of?
CT scanners are composed of three important elements: an X-ray tube, a gantry with a ring of X-ray sensitive detectors, and a computer. In this method, images are created using the same physics principles as in conventional radiography.
How do you make a CT scan machine?
Here’s what you’ll need:
- An X-ray tube consisting of an anode and a cathode.
- Collimators, which are devices that allow the X-ray photons to be targeted at a specific part of the body.
- A detector array.
- A power source.
- Copper or aluminum filters to remove low-energy X-ray photons.
Who invented the first CT scan machine?
Godfrey Hounsfield
Godfrey Hounsfield, a biomedical engineer contributed enormously towards the diagnosis of neurological and other disorders by virtue of his invention of the computed axial tomography scan for which he was awarded the Nobel Prize in 1979.
Why was CT scan invented?
So, what was the catalyst for his work with the CT scan? According to Hounsfield, the idea to invent such technology came to him while on vacation. At the time, all he wanted was to reconstruct a 3D picture of a box. He intended to achieve this by re-imagining the object as a series of slices.
What was used before CT scans were invented?
Before computed tomography, tomographic images could be made by radiography by focal plane tomography, representing a single slice of the body on radiographic film. This method was proposed by the Italian radiologist Alessandro Vallebona in the early 1900s.

What year was CT scan invented?
1967
In 1967 Sir Godfrey Hounsfield invented the first CT scanner at EMI Central Research Laboratories using x-ray technology. In 1971 the first patient brain CT was performed in Wimbledon, England but it was not publicized until a year later.
What does a CT scan show?
CT scans show a slice, or cross-section, of the body. The image shows your bones, organs, and soft tissues more clearly than standard x-rays. CT scans can show a tumor’s shape, size, and location. They can even show the blood vessels that feed the tumor – all without having to cut into the patient.
