Rouse v. Walter & Associates, L.L.C.
513 F. Supp. 2d 1041 (S.D. Iowa 2007)
You can read an article of Rouse and Wilson's original research here.
The company they founded, Biotronics, Inc. (biotronics-inc.com) still exists, and should not be confused with BioTronics, Inc. (biotronics.com), which is a medical equipment management services company. Biotronics has since branched out from beef ultrasounds to pork ultrasounds. Wilson and Amin still work there.
