Abstract
Effects of kVp, voltage wave form, added filter, and tube current on three-dimensional reconstruction from x-rays have been investigated in relationship to sampling time,spectral heterogeneity, contrast, quantum noise, and patient dose. Comparison of statistical limitations with and without a water-bath indicates that scanners which employ a water-bath are comparatively inflexible in this regard. A degree of flexibility in the choice of kilovoltage and filter seems both desirable and feasible in scanners which do not use a water-bath. Minimization of patient dose is also limited by statistical factors. Reconstructions from measured data have been carried out to demonstrate the relationship between these factors.
