IDEA #9TZ4KI Technology Of Precise Estimate Of Blood Flow's Parameters "Truth"

LIFE SCIENCES • MEDICALRESEARCH TECHNOLOGY OOFF PRECISE ESTIMATE OOFF BLOOD FLOW''SS PARAMETERS ""TRUTH"" DescriptionEstimation of parameters of blood flow in various organs and tissues is a basis of instrumental diagnostics of cardiovascu(cid:2) lar diseases. Ultrasonic Doppler examination is the most wide(cid:2) spread method of noninvasive estimations of blood flow's parameters. It is based on the spectral analysis of an Doppler echosignal, which frequency’s shift transfers the information about the distribution of the blood flow velocities in the field of interest. Serious lack of known variants of such research is low accuracy of estimation of parameters of hemodynamics. Traditionally in the spectral analysis of improvement of accura(cid:2) cy of measurements achieve by increasing of duration of echosignal's sample. However, this way does not give desir(cid:2) able result in ultrasonic Doppler echoscopy of blood flow owing to its high dynamism. Changes of blood flow's speed connected with cardiocycle even on traditionally short sam(cid:2) ples of echosignal (10(cid:2)20 ms), gives essential expansion of spectrum and, as consequence, decrease of resolution and accuracy of the spectral analysis. The technology "Truth" provides measurement of parameters of blood flow with an error essencially smaller, than traditional technologies allow and gives the possibility to estimate the true blood flow parameters. Development of technology "Truth" has been started during execution of the project *793 “ Creation of an ultrasonic cere(cid:2) bral Doppler angiograph having a three(cid:2)dimensional image reconstruction (USCDA) ” Innovative Aspect and Main Advantages • Highly effective iterative method of compensation of spec(cid:2) tral expansion of Doppler signal which eliminates correspon(cid:2) ding errors in an estimation of speed's parameters of the blood flow caused by its high dynamism; • Unprecedented reliability of estimations of hemodynamic's parameters (that is especially important in making decision concerning necessity of cardiovascular, cerebrovascular and other vascular surgical interventions); • An opportunity of integration in earlier released ultrasonic Doppler scanners (for example, ULTIMA PA). Introduction of technology "Truth" into medical practice would improve quality of diagnostics of cardiovascular and cere(cid:2) brovascular pathology, and also vascular diseases of other localization. 128 Pic.1.
