Advanced Physics for Brachytherapy 2018

Strategies to reduce uncertainties for brachytherapy planning and treatment

•

Organ filling protocols

• Optimize target contouring (MRI, US, …)

• Adaptive planning to reduce large systematic/random variations between fractions (online planning, plan of the day)

• Advanced in vivo dosimetry (dose rate time profiles)

• Online imaging in treatment room (comparable to CBCT in EBRT) – limited by infrastructure of the BT suite (imaging in treatment room)

➢

CBCT, in-room MRI/CT, 3D ultrasound, …
