1
Q
Absorbed dose
A
A measure of the biologically significant effect produced by ionizing radiation
Referred to as dose
2
Q
Exit dose
A
Absorbed dose delivered by a single fixed beam at the beam exit point
To signify the dose delivered to Dmax at the exit point
3
Q
MADR
A
Maximum absorbed dose rate
Also called peak absorbed rate
4
Q
Target dose
A
Dose prescribe at point of interest
5
Q
Integral dose
A
Summation of the dose to the entire irradiated area and represents the total energy absorbed
6
Q
Given dose is
A
Dose as dmax and called applied dose
7
Q
Dmax
A
The point where maximum absorbed dose occurs for single field beams
8
Q
PDD
A
The ratio expressed percentage of the absorbed dose at any depth “d” to the absorbed dose at fixed depth “d0” along the central axis of the beam
