Which position is this?
Hughston Method
( what it looks like when you use the collimator for leg support, don't forget to protect foot if collimator is hot)
Settegast (tangential)
1.) How much is the knee flexed?
2.) whats the technique (all the same for tangential)
3.) Whats the CR angle and position
