Treatment verification: importance for BT

 Risk of errors (high compared to EBRT):  Manual procedures: errors in reconstruction of catheters, applicator length, applicator-afterloader connection, etc.  Mechanical equipment: obstructed transfer tubes and applicators, machine failure, etc.  High impact of errors/uncertainties:  High dose gradients  Hypofractionation schemes  Challenge: Low patient volume (compared to EBRT):  Resource investment limitations  Small clinics: Reduced expertise and experience
