Hi,

I am looking for information on the Ultrasonic Process Tomography for discontinue  phase two-component flow imaging. Currently our g=
roup has developed a prototype system consisting of a transducer ring of 36 elements. A large scale transputer array was also built =
dedicated at the geometric and algorithmic parallelism for the real-time ultrasound image reconstruction. Real-time image reconstruc=
tion has been achieved at the fresh rate about 50 frame/s (about 20ms) at the image resolution of 200x200. In order to calculate the=
 void rate of the flow (this system is initially designed to imaging the bubbled flow, water or oil) an algorithm of parallel implem=
ented Hough Transform has been developed and used to identify the potential bubbles geometrically. I would appreciate any informatio=
n relating to such topics
