From: Aortic acceleration as a noninvasive index of left ventricular contractility in the mouse

Experimental setup to simultaneously measure ascending aortic Doppler flow velocity using DFVS, left ventricular dimensions and ascending aortic flow velocity using VEVO770 system with 710B probe. Also, shown in the figure are lines representing the horizontal plane, and the angle of orientation of 20 MHz Doppler probe (≤ 25°) and that of the 710B probe (≈70°).
