Cone beam computed tomography (CBCT) is often used for patient setup based solely on bony anatomy. The goal of this work was to evaluate whether CBCT dose can be lowered to the level of kV image pair doses when used for bony anatomy‐based IGRT without compromising positioning accuracy.

你能走多低？CBCT减量研究

锥形束计算机断层扫描（CBCT）通常仅基于骨骼解剖结构用于患者设置。这项工作的目的是评估在用于基于骨骼解剖的IGRT时，是否可以将CBCT剂量降低到kV图像对剂量水平，而不会影响定位精度。
