    Different types of flood sources were applied toproduce bone phantom images, and the quality of the resulting phantom images was studied. The measurements were made with 37-PMT circular detector ... gamma cameras and with rectangular detectors SPECT devices, with the Scanflex Transbone transmission bone phntom.Phantom images were produced with a 99m-Tc fillable flood source, a 57-Co flood source and dynamic line phantom (Veenstra Instrumenten B.V.). Images were acquired with the number of counts collected under routine clinical conditions (600 000-8000 000 counts) and also with a high number of counts (2 million counts) and were documented on X-ray films. The images were interpreted by three independent experienced observers. From the scores, ROC (receiver operating characteristic) curves were generated. The quality of the images was characterized by the area under the ROC curves. There were no significant didderences between the ROC curve areas of the images produced with the same parameters. The differences between the routine and the high-count images were significant. It is concluded that all of the investigatedflood sources are suitable for the production of bone phantom images for the quality control of nuclear medicine imaging procedures.
