Daily flood‐field uniformity evaluation serves as the central element of nuclear medicine (NM) quality control (QC) programs. Uniformity images are traditionally analyzed using pixel value‐based metrics, that is, integral uniformity (IU), which often fail to capture subtle structure and patterns caused by changes in gamma camera performance, requiring visual inspections which are subjective and time demanding. The goal of this project was to implement an advanced QC metrology for NM to effectively identify nonuniformity issues, and report issues in a timely manner for efficient correction prior to clinical use. The project involved the implementation of the program over a 2‐year period at a multisite major medical institution.

使用结构噪声指数的核医学自动化质量控制。

每日洪水场均匀性评估是核医学（NM）质量控制（QC）计划的核心要素。传统上，均一性图像是使用基于像素值的度量标准进行分析的，即积分均一性（IU），它通常无法捕获由伽马相机性能变化引起的细微结构和图案，需要进行主观且耗时的目视检查。该项目的目标是为NM实现先进的QC计量，以有效识别不均匀性问题，并及时报告问题，以便在临床使用之前进行有效纠正。该项目涉及该计划在多站点主要医疗机构中为期两年的实施。
