On my list of recommended books for Registry Review, I would have to include:

Sandra Hagen-Ansert  Textbook of Diagnostic Ultrsonography

Terence Case             Introduction to Noninvasive Vascular Lab   (?)

Barton Bean               Vascular Technology (From ESP Seminar)

Sydney Edelman has the best physics references!

I teach in a accredited ultrasound program and use these books constantly.  

In response to your concerns about licensure and SDMS.  I think that Lab
Accreditation will solve most of our problems.  I am not sure that licensure
is the solution, since everytime that begins we seem to get grouped with
Radiology, which we are not.  

In an unrelated topic, It is soo hard to get on AOL that I am ready to
switch, when that occurs, however I will need to know how to subscribe again!
 I can't remeber how I got here and I can already tell that MS Network (which
is probably what I will go to) is not as user friendly as AOL   WAS!!!

thanks
