Modern Brachytherapy: Treatment Delivery Verification

▪ Delivered Treatment versus Planned Treatment

Currently we assume that:

• The geometry and location of the implanted catheters

• The connection of channels to implanted catheters

• The length of the channels

• The source movement patterns ( dwell positions and dwell times ) within the implanted catheters

• The patient anatomy at the relevant location

are during treatment delivery exact as considered and planned in the RTP.
