Questions and Answers
What is the basis for the Nobel Prize in Medicine?
What is the basis for the Nobel Prize in Medicine?
- The classification of CT based on X-ray tube and detector movement
- The rotating mechanism of CT scanners
- The introduction of higher generation CT scanners
- The first generation of CT, involving one X-ray source and one X-ray detector (correct)
Why doesn't a higher generation number necessarily mean a higher performance system?
Why doesn't a higher generation number necessarily mean a higher performance system?
- Higher generation CT scanners have more advanced X-ray tube and detector movement
- Higher generation CT scanners may have similar or inferior performance (correct)
- Higher generation CT scanners have better component arrangement
- Higher generation CT scanners have slower rotating mechanisms
What is the characteristic of the geometry in the first generation CT scanners?
What is the characteristic of the geometry in the first generation CT scanners?
- It involves multiple X-ray sources and detectors
- The source detector assembly returns to its starting position at the end of translation (correct)
- The source and tube were not rotated with respect to the patient
- The X-ray source would only translate once for each view
