CT imaging for radiotherapy of lung cancer
• Many imaging modalities are
possible for lung cancer
• CT is the basic imaging
modality in radiotherapy of
lung
• Soft tissue contrast is good in
lung, densities for RT are
important
• A 3D CT scan shows
substantial breathing artifacts
• A ‘slow scan’ reveals the
extent of the motion, but shows
a blurred image
• A 4D CT scan is preferable
