Questions and Answers

What is the primary purpose of using fast CT scanners like the EBCT scanner?

  • To introduce more spatial and contrast resolution
  • To reduce motion artifacts and loss of spatial and contrast resolution (correct)
  • To speed up the heart beating rate artificially
  • To increase motion artifacts and loss of spatial and contrast resolution

    • What role does the patient's electrocardiogram (ECG) play in the imaging process?

  • Monitors the patient's blood pressure during scanning
  • Generates images without the need for a scanner
  • Delays the imaging process
  • Provides prospective imaging (correct)

    • In retrospective imaging developed for spiral/helical CT scanning, how is the ECG utilized?

  • Controls the lighting in the scanning room
  • Correlated with image reconstruction (correct)
  • Helps in cleaning the scanner components
  • Used to adjust the patient's position
