Conversion coefficients for dose estimation from dose-length product (DLP) in CT examination

Radiation dose from a CT examination in standard body regions can be estimated from the dose-lenght product (DLP) that each CT outputs. This table shows known commonly used coefficients and their adjustment in two particular CT machines. The calculation of the efective dose estimation is:

E(mSv) = coefficient * DLP * 0.001

The most recent recommendation is based on the ICRP 103 publication (last column).
