State regulations require that CT radiation output be measured using a dosimeter after major service. The most common major service is tube replacement. We hypothesized that historical QC data could be used instead to determine if output measurements are necessary, potentially reducing the need for output measurements that require an on-site visit by a qualified medical physicist.

重新审视在计算机断层扫描中更换 X 射线管后对辐射输出测量的需求

国家规定要求在主要服务后使用剂量计测量 CT 辐射输出。最常见的主要服务是管更换。我们假设可以使用历史 QC 数据来确定是否需要输出测量，从而可能减少对需要合格医学物理学家现场访问的输出测量的需求。
