Intrafraction patient motion is a well-documented phenomenon in radiation therapy. In stereotactic radiosurgery applications in which target sizes can be very small and dose gradients very steep, patient motion can significantly impact the magnitude and positional accuracy of the delivered dose. This work investigates the impact of intrafraction motion on dose metrics for small targets when treated with a virtual cone.

研究使用虚拟锥体治疗小目标时分次内运动对剂量学结果的影响

次间患者运动是放射治疗中一个有据可查的现象。在目标尺寸可能非常小且剂量梯度非常陡峭的立体定向放射外科应用中，患者的运动会显着影响所输送剂量的幅度和位置精度。这项工作研究了当用虚拟锥体处理时，分次内运动对小目标剂量指标的影响。
