Dual kilovoltage at computed tomography: a prereconstruction method for estimation of effective atomic number and
Neuroradiology
|January 1, 1978
Abstract:
Some of the prior efforts at using postreconstruction dual kilovoltage CT scans to obtain an effective atomic number and electron density are reviewed. A prereconstruction method which avoids beam hardening is applied to a phantom and a beginning clinical trial is described.
