Computed Dosimeter Dose Index on a 16-Slice Computed Tomography Scanner
A computed tomography dose index can be used to quantify the radiation dose received during a CT scan and it is an indicator of the radiation dose to the polymetaylenmetaAcrylate (PMMA) standardized phantom. The objective of this study was 2-fold.
