Sorta about right for what I have seen to - except to note that on a c-arm 
fluoro there is a definite - and not surprising - aniosotropy to the 
scatter:  A considerable forward angle - ie. much greater along side the II 
downstream of the phantom that along side the tube - or even as near the 
patient but tube side!
