    45 degrees seems a little steep to me. but if everyone uses it then i will.
    i was thinking 5 -10 degrees less?
    all i am doing with this is making sure my facet rhizotomy needles are not too close to the foramen.

    Start to look at the facets in oblique view. When you can see sharp cortical boarders, stop. 45 degrees will get you close but you can do better if you
    use the facet cortices.

    Look at figure 8.6 in the link below:

    I go 30 degrees contralateral oblique and then fine-tune to get sharp foraminal borders
