Abstract

The effect of surface waves, generated by moving the scanning arms in water phantoms, on radiation dosimetry is studied. It is shown that in large water tanks, high arm speeds can result in dosimetric errors of up to 5%. The measurements that are started after damping the water waves can result in about a 50% improvement in accuracy of measurements. It is shown that the water surfaces at the start of the measurements have high fluctuations that transform to a steady phase by elapsing time.

摘要

研究了在水模中移动扫描臂所产生的表面波对辐射剂量测定的影响。结果表明，在大型水箱中，较高的臂速可导致高达5%的剂量测定误差。在水波衰减后开始的测量可使测量精度提高约50%。结果表明，测量开始时水面波动较大，随着时间推移会转变为稳定状态。
