Question:medium

Cardiac images obtained with conventional CT may not be precise due to:

Show Hint

In medical imaging physics: - Anatomical Motion during projection acquisition causes Motion Artifacts (blurring and streaks). - Because conventional CT scanners have slow rotation speeds relative to a beating heart, they blur cardiac structural details. Resolving coronary arteries clearly requires ultra-fast rotation times or ECG-gated acquisition loops.
