Porównanie dwóch metod weryfikacji geometrycznej podczas radioterapii raka prostaty

CBCT allows the correction of displacement of the prostate based on the soft tissues and the bone anatomy. 2D-kV allows correction of prostate shifts only on the basis of the bones. The results obtained by the method of 2D-kV are flawed by 20% (along the sagittal axis) and by 9% (along the vertical axis) error with respect to the CBCT method.
