Abstract

Daily quality control testing of a γ-camera is of the utmost importance in assessing whether the camera is suitable for clinical use. The aim of our study was to assess the suitability of a fillable Ce-based flood field phantom developed in-house for daily quality control testing of γ-cameras. Daily uniformity testing was performed for 113 d using the fillable Ce phantom and a commercially available sheet-type Co phantom, and the results were compared. The average integral uniformity obtained by the Ce and Co phantoms was 3.24% and 2.72%, respectively, for detector 1 and 3.31% and 2.78%, respectively, for detector 2. The Ce phantom we developed is a suitable alternative to the commercially available Co phantom.

摘要

对γ相机进行每日质量控制测试对于评估该相机是否适合临床使用至关重要。我们研究的目的是评估自行研制的可填充铈基泛源模体用于γ相机每日质量控制测试的适用性。使用可填充铈模体和市售片状钴模体进行了113天的每日均匀性测试，并对结果进行了比较。对于探测器1，铈模体和钴模体获得的平均积分均匀性分别为3.24%和2.72%；对于探测器2，分别为3.31%和2.78%。我们研制的铈模体是市售钴模体的合适替代品。
