Ultrasound technology developer EchoCath reports the successful operation of a new Doppler system to improve the transcutaneous measurement of blood flow. When fully developed, the system could provide accurate, low-cost blood velocity measurement through the skin, according to EchoCath CEO Frank DeBernardis.
The new method, so far demonstrated only in the laboratory, uses three EchoCath diffraction-grating transducers, the Princeton, NJ-based firm said. By deploying the transducers in a star-like arrangement, EchoCath believes blood velocity can be measured independently of the orientation of the blood vessel to the transducer array.
An EchoCath team of engineers presented the method today at the 2000 IEEE Ultrasonics Symposium in San Juan, Puerto Rico. EchoCath expects to begin clinical testing of prototype instruments using this method by the middle of 2001.
