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 141 Ce-based flood field phantom developed in-house for daily quality control testing of γ-cameras. Methods: Daily uniformity testing was performed for 113 d using the fillable 141 Ce phantom and a commercially available sheet-type 57 Co phantom, and the results were compared. Results: The average integral uniformity obtained by the 141 Ce and 57 Co phantoms was 3.24% and 2.72%, respectively, for detector 1 and 3.31% and 2.78%, respectively, for detector 2. Conclusion: The 141 Ce phantom we developed is a suitable alternative to the commercially available 57 Co phantom.
