Abstract :
Progress in the quantitative use of CT numbers for patient diagnosis has been limited because of scanner drift, energy dependence, and various artifacts. The nature of these errors is discussed, and methods of evaluating them are described. In addition, remedial measures are mentioned, including the use of a three-point calibration phantom.
