A Novel Ce-Based Flood Field Phantom: Assessment of Suitability for Daily Uniformity Testing in a Clinical Nuclear Medicine Department.

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.
