Fri March 12th 2010 16:00 ZH286 | Seminar | Some recent developments in micro-PIV Christian Poelma |
Details:Ongoing research in the field of in vivo cardiovascular experiments using microscopic Particle Image Velocimetry will be discussed. Using a recent study in the outflow tract of an embryonic chicken heart as a starting point, I will discuss some innovations that have been introduced to improve the accuracy and applicability of PIV. These include: (1) a posteriori phase-reconstruction of periodic flows (2) the reconstruction of the out-of-plane component (either using the continuity equation in multi-planar measurements or from correlation peak heights in single plane measurements), (3) the role of the depth-of-correlation on observed velocities at low magnifications, and (4) unexpected complications (and a solution) in finding average flow fields in transient flows. |
