摘要： Contrast agents may more effectively clear a clot if they are as close to the clot as possible. Radiation force may effectively push and/or pull the contrast agents next to the clot and away from the middle of any flow channels. By transmitting driving acoustic energy, the contrast agents may be positioned for treatment that is more effective by destruction.

摘要： Control of the sonothrombolysis treatment is automated based on feedback from ultrasound. The region to be treated may be tracked to provide ongoing treatment at the desired location. The treatment may be triggered based on detection of sufficient perfusion. The number or intensity of destructive ultrasound pulses may adapt to the number of remaining contrast agents. The treatment may be ceased or modified based on the efficacy.

摘要： Highly specific measurements of flow in vessels, such as the coronary artery, can be obtained by processing cubic fundamental information. By showing flow in vessels with a high degree of contrast-to-tissue specificity, ultrasound based 3D contrast agent based coronary artery angiograms may be possible. Measurement and display of the velocity of agent from the cubic fundamental signal is provided simultaneously with display of cubic fundamental energy, such as providing a display map indexed by both energy and velocity. High pulse repetition frequency (PRF) for cubic fundamental detection in conjunction with long velocity measurement intervals may increase low velocity sensitivity and measurement precision. Pulsed wave (PW) Doppler may be improved by using a cubic fundamental sensitive pulse sequence. Using cubic fundamental sensitive techniques with other motion estimation techniques, such as two-dimensional velocity estimation or speckle tracking, may operate better than using other contrast agent detection techniques because of substantially reduced clutter.

摘要： Contrast agents are characterized with ultrasound. Flowing or unbound contrast agents are distinguished automatically from bound or relatively stationary contrast agents. The bound or relatively stationary contrast agents are highlighted on a display. A processor distinguishes different types of contrast agents or contrast agents in different binding states with relative signal strength or velocity. Attached contrast agents are differentiated from phagocytosed contrast agents. Monitoring absolute signal strength as a function of time may indicate binding. Any one or more of these features may be used.

摘要： Contrast agent enhanced medical diagnostic imaging is improved by selecting particular frames of data. Frames of data are acquired over time. Information from the frames of data are combined, such as for a time intensity curve or maximum intensity processing. Rather than combining information from each of the frames, information from some frames is not used. Frames are selected for inclusion. In one embodiment, the selection is based on one type of data (e.g., B-mode) for combining information for another type of data (e.g., contrast agent data).

摘要： Contrast agents are manipulated with acoustic radiation force while ultrasound imaging. Continuous waves for acoustic radiation force are transmitted. Substantially simultaneously, pulsed waves for imaging are transmitted. Low mechanical index continuous and pulsed waves may be used to increase binding efficiency of drug containing contrast agents with the tissue for treatment. Various techniques may be used to minimize the effect of the continuous waves on imaging with the pulsed waves. The acoustic radiation force may be transmitted with an amplitude profile and/or unfocused or defocused.
