Breathing motion artefacts in planning CT-scan

Avoid motion artifacts in planning CT-scan (i.e. avoid systematic errors)

 breathhold scanning: multislice CT-scanner, only 3D scan in 1 phase  gated free-breathing scanning: single slice scanner, only 3D scan in 1 phase

 4DCT scanning: multislice CT-scanner , 10 3D CT-scans in 10 breathing phases
