Dose reduction and image quality in CT angiography for cerebral aneurysm with various tube potentials and current settings
OBJECTIVES: The purpose of this study is to investigate the image quality on both axial and three-dimensional CT angiograms of the brain at various tube potentials and currents, and to propose the use of descriptors for evaluating the image quality of three-dimensional CT angiograms using entropy an...
