Pre-plan versus intra-operative plan
Pre-planning
• Outpatient TRUS prior to implant
• Positioning probe as outpatient situation
• Less OR time needed
• No possibility for interactive planning
• Oedema effect not taken into account
• No physicist/dosimetrist needed in OR
• Number of seeds to order more accurate
Intra-operative plan
• TRUS at time of implant
• Probe stays in position during whole treatment
• More OR time needed
• Interactive planning possible
• Geometry changes are taken into account
• Physicist/dosimetrist needed in OR
• Risk of inappropriate seed ordering
