MME TV: Hemodynamics - A discussion of arterial waveforms
This week we review temporal flow patterns of arterial waveforms. Why does a perfectly healthy popliteal artery look very different from a perfectly healthy internal carotid artery? The answer lies in the tissue requirements at the end of that vessel......
MME TV: Aliasing
What is aliasing? Dr. Shepherd addresses this issue in our VIP Physics course. Watch a portion of his lecture here that describes what actually happens when we sample high velocity flow....

MME-Sunda Shelf Archaeology Project- "Anomaly Discussion"
The crew of the Southern Sun discuss the discovery of an anomaly seen on the depth sounder and make a plan on how to approach the problem and discover what it is.Husband and wife team, Hans and Roze Berekoven are the Maritime Mysteries Explorers. Th......
MME TV: Fetal Circulation - A Quick Review
Dr. Shepherd reviews the course of blood flow from the uterine artery through the placenta into the umbilical vein through the ductus venosus and beyond....
MME TV: Perforated IUD
Last week we discussed imaging technique for IUD placement and the importance of a complete sagittal and coronal sweep of the uterus. This week we will review a perforated IUD....
Web Seminar: Hemodynamics of Counterpulsation
http://www.maquet.com/The Intra-aortic balloon pump (IABP) has been the first-line choice for mechanical circulatory support around the world due to its clinical efficacy, safety profile across a broad range of patient care scenarios, and low cost. I......
Experimental Measurements of AAA Hemodynamics
(September 4, 2008) Roberty Peattie, PhD, discusses his research of flow fields in physically replicated models of the human aorta to discover the velocity of flow which causes wall shear stresses.2008 Stanford AAA Summithttp://vascular.stanford.edu/......

MME TV: Placenta previa
Dr Shepherd walks us through a common mistake in the diagnosis of placenta previa during the transabdominal approach. It is the lower uterine contraction. An awareness of the average length of a cervix is critical in distinguishing the internal os fr......
Spectra of Basic Waveforms
The spectra of basic waveforms: sine, triangle, square, and sawtooth. The sine wave has a single partial (the fundamental); the triangle wave has only odd harmonic partials with relatively small amplitudes proportional to one over the square of the p......
MME TV: Fistula Evaluation
CC walks us through a radiocephalic arteriovenous fistula case study. The main purpose of this exam is to find out if the fistula is working properly. You want to evaluate for any flow limiting stenosis, the formation of thrombus and any inflow or ou......
