|
Exposure |
Ability of xrays to ionize a volume of air.easured in roentogens (R) |
|
|
Kerma |
Aka absorbed dose. Air kerma is xray energy absorbed in quantity of air |
|
|
Absorbed dose |
Amount of xray energy absorbed in unit of mass. Measured in grays (Gy) |
|
|
Effective dose |
Accounts for the tissue type that the radiation was absorbed. Approximates the relative risk from exposure. Measured in sieverts (Sv) |
|
|
CT dose index (CTDI) |
Approximate measure of the dose received in a single CT section or slice |
|
|
CTDI 100 |
A fixed measurement taken with a 100mm long pencil ionization chamber and makes no reference to slice number |
|
|
CTDI-W |
Internationally accepted weighted dose index. Yields more of an accurate dose approximation by summing 2/3 of exposure recorded at the periphery with one third the centrally recorded dose |
|
|
CTDI-vol |
Used to approximate the radiation dose for each section obtained during a helical scan. |
|
|
Multiple scan average dose (MSAD) |
Similar to CTDI - vol for conventional step and shoot methods. The calculation of the average cumulative dose to each slice within the center of a scan consisting of multiple slices |
