摘要

摘要：本文的目的是研究钇-90放射栓塞各步骤的测量不确定度。我们研究了初始剂量测定时剂量校准器精度、测量仪精度和剂量率测量时操作人员读数不确定度对测量不确定度的贡献。计算这些不确定度的传播，以确定各种规定剂量的最终剂量传递不确定度。在剂量测定和剂量率测量的每一步操作中，特别是在低规定剂量的情况下，与操作相关的不确定性会显著影响最终剂量的百分比。

Y-90 Treatment Dose Delivery Uncertainty from Measurement Uncertainties.

Abstract: The objective of this note was to study the measurement uncertainties at each step of Yttrium-90 radioembolization. We studied the measurement uncertainty contribution from the dose calibrator accuracy during the initial dose assay, the survey meter accuracy, and the operator's reading uncertainties during the dose rate measurements. The propagation of these uncertainties was calculated to determine the final dose delivery uncertainty for various prescribed doses. The percentage of final dose delivered could be affected significantly by the uncertainties associated with operation at each step of dose assay and dose rate measurements, especially for low prescribed doses.
