The imaging process has two fundamental stages: detection and display. The detection stage can be quantified rigourously using Shannon's information theory. This requires the contrast scale (CS), modulation transfer function (MTF), and noise power spectrum [N(f)] to be combined into a signal-to-noise ratio (SNR). This results in two fundamental summary(More)
Although computed tomography (CT) delineation of normal white matter of the cerebral hemispheres has been well documented, there has been no description of white matter within the cerebellum. Through the use of phantom studies, CT number correlations between cerebellum and cerebral hemispheres, and anatomic correlation with in vitro specimens, the ability(More)
