BIOFLUID MECHANICAL STUDIES IN MODELS OF BLOOD
VESSELS AND SOME APPLICATIONS
Lasers are used in a wide variety of medical applications.
While laser catheters have beem developed for highly accurate velocity
measurements, these are invasive; noninvasive techniques are more
desirable but not as precise. The laser is, however, a great tool
for in vitro measurements. Several groups internationally are using
the laser in the study of local velocity dustribution in microscopic
areas of specially constructed models. Laser Doppler anemometry is
widely used to measure the local, time-dependent velocities, while
phase Doppler anemometry has been developed to measure particle size,
distribution and velocity. Most recently, laser analyzer techniques
have been developed for analyzing the particle size of two phase flow
systems. It has become increasingly important for physicians to visualize
blood flow. In addition to the techniques mentioned above, several
laser sheet techniques have been developed for precise measurements.
This paper presents a short review of laser techniques and shows some
applications especially for the laser-Doppler anemometer.
