A Handbook |
|
|
|
|
Transonic Systems, the pioneer of transit-time ultrasound flowmetry, has produced and published an 80-page handbook, "Flow-based Intraoperative Graft Patency
Assessment" in collaboration with B. Mindich, MD,
chief of cardiac surgery, The Valley Hospital, Ridgewood, NJ. The handbook is available in quantities from Transonic Systems (click here), or in separate pdf files below. To view individual chapter of the handbook, click on the links below.
