Advanced Physics for Brachytherapy 2018

Why in vivo dosimetry?

• Prevent, rare but major accidents

➢ Brachytherapy procedures are performed without the safeguards of Record and Verify systems.

• Human errors are the main cause of inadequate brachytherapy dose delivery, although mechanical failures occur as well. Examples are:

➢

exchanged guide tubes;

➢

misadjusted applicators;

➢

reconstruction errors;

➢

mechanical errors.
