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.
