-
BSF is equal to ______ at Dmax.
TAR
-
PDD is directly proportional to:
- Field Size
- Energy
- Distance (SSD)
(PDD needs the FED)
-
PDD is inversely proportional to:
Depth
(both PDD & TMR are inversely proportional to depth)
-
TAR & TMR are directly proportional to:
Field Size & Energy (aka beam quality)
(TMR = FE)
-
TAR & TMR are inversely proprtional to:
Depth
(both PDD & TMR are inversely proportional to depth)
-
TAR & TMR are independent of:
SSD
(that's why it's perfect for SAD tx's)
-
BSF or PSF is dependent on:
Field Size & Energy
-
Penumbra is directly proportional to:
-
Penumbra is indirectly proportional to:
SCD
-
TAR = TMR X _____
BSF
TAR = TMR X BSF
