I find that it is rare with the new ultrsound equipment that a 60 degree angle is not obtainable. You can do the "heel toe" motion, swing the Doppler box, all that stuff, so its almost always do-able. Also changing from linear to sector image can help with tortuous distal ICA's etc.

I work in a small city with a new ultrasound program at the university. There is also a new vascular ultrasound program with students rotating through my lab. I am finding these students are being taught that the angle of insonation should be 60 degrees and nothing else no matter how the vessel is coursing. My students are telling me that he other surgeons' lab and the general US depts. in the 2 hospitals also incorporate this same school of thought. For me, it has always been 60 degrees or less. Is this common practice in other communities? I would appreciate your feedback.
