Computed Dosimeter Dose Index on a 16-Slice Computed Tomography Scanner
Dose-Response, 2022 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.

Computed Tomography (CT) Standards [PDF]
, 2000 There is currently no standardized method to check the measurement capabilities of computed tomography (CT) systems within industry. The current method to determine the functionality of CT systems is by use of a test phantom to represent the actual part to be tested.
