INTRACORPORALEN SONDE ZUR GENAUEN BESTIMMUNG DER GESCHWINDIGKEIT EINER FLÜSSIGKEIT, INSBESONDERE DES DURCHFLUSSES DURCH DIE AORTA |
摘要 |
The probe according to the invention comprises: - at least one ultrasonic transducer (4) with wide beam (4a), fixed on a support block (3) making it possible to measure, by Doppler effect, the velocity of a moving target (11), - at least one ultrasonic transducer (5) with a narrow beam (5a), fixed on a support block (3) and whose beam is in a known relative position with respect to that of the wide beam (4a), - and a control and processing unit (8) comprising means (14,15) for measuring and processing characteristics of the signal from the narrow-beam transducer (5), in order to determine the only suitable orientation of the wide-beam transducer which allows exact measurement of the flow rate. <IMAGE> |
