Bladder
Challenges
Full and empty bladder scans (for ITV generation)
• Highly distensible, V depends on filling
• Moving (positioning, respiration, bowell filling)
• SimDVH unlikely the same as TxDVH...
• Aim at constant bladder filling (difficult to maintain)
• Different regions – Different endpoints
