- Cohort 1
- description
- Cohort of 18 subjects evaluated. Subject will receive 4DCT cine acquisition gated using a respiratory signal from real-time position management (RPM) gating system. Maximum number of allowable images that may be acquired increased from 3000 to 5999 images. Total imaging time for each subject \< 60 minutes.
