Contrast agent image with a () as a contrast agent specific ultrasound detection

摘要

Highly precise measurements for a flow in vessels, for example, of the coronary artery, can be ascertained by the cubic fundamental information is processed. By means of the display of the flux in vessels with a high contrast - to - fabric - degree of accuracy are ultrasound - based 3 - d - a contrast agent - based coronary arteries angio possible programs. The measurement and the display (20) of the speed of the agent from the cubic fundamental signal (32), simultaneously with the display of the cubic fundamental energy (34) is provided, so that a display image is obtained which is indicated with the energy, and with the speed. A high pulse repetition frequency (prf) to the cubic fundamental detection in connection with long speed mes intervals, the sensitivity with respect to small speeds and the accuracy of measurement (30) increase. Pw - doppler can be improved by providing a cubic fundamental sensitive pulse sequence (40) is used. The use of cubic fundamental sensitive techniques with other movement sch etching techniques, for example, a two-dimensional speed estimation (56) or speckle tracking (54), can operate better than other contrast means detection techniques on the basis of a substantially reduced spurious echoes.
