Dosimetry basics and dose optimization strategies for CT examinations
https://doi.org/10.24287/1726-1708-2018-17-3-127-132Abstract
This article describes basic approaches to CT dose calculations. Basic scan parameters and their influence on the dose are described, as are the typical strategies for dose saving in the single medical hospital environment.
