PURPOSE This work sought to quantify a radiology team's assessment of image quality differences between two CT scanner models currently in clinical use, with emphasis on noise and low-contrast detectability (LCD). METHODS A water phantom and a Kagaku anthropomorphic body phantom were scanned on GE Discovery CT750 HD and LightSpeed VCT scanners (4 each)(More)
We present mass models for three S0 galaxies with a strong disk component observed almost on edge (NGC 2732, NGC 4111, and NGC 4350). For the analytical representation of the surface-brightness distribution, the method of MultiGaussian Expansion, first presented by Monnet et al. (1992: A&A 253, 366) is applied to V -band surface photometry. A simplified(More)
