Abstract
A pendant-geometry, cone-beam breast CT scanner has been constructed and is undergoing thorough testing in our facility. The system is capable of acquiring 30 frames/sec in 2×2 binning mode (1024×768 pixels) using a flat panel detector coupled to a thallium-doped cesium iodide scintillator. The DQE of the detector system for RQA5 and RQA9 x-ray beam qualities were computed, and the low frequency DQE values were 65% and 57% respectively at approximately 16 μR/frame. The results also shown that minor improvements in DQE are achieved for exposures greater than 16 μR/frame. It is expected that the scanner will be available for the imaging of human volunteers in the first half of 2004.
