Abstract
Ultrasound diagnosis and therapy for disruption of a thrombus are provided with a same ultrasound system. A same transducer and system images contrast agents and ruptures the contrast agents to mechanically weaken or destroy a thrombus.

14. In a computer readable storage medium having stored therein data representing instructions executable by a programmed processor for contrast agent ultrasound imaging and therapy, the storage medium comprising instructions for:
using one transducer to image a blood clot and contrast agents and to mechanically break or weaken the blood clot with disruption by at least some of the contrast agents. - View Dependent Claims (15, 16, 17, 18, 19)

20. A method for contrast agent ultrasound imaging and therapy, the method comprising:
-
first transmitting acoustic energy with an ultrasound transducer to a thrombosis, the transmitting being about 0.5 MI or less;
receiving, with the ultrasound transducer, acoustic energy in response to the first transmitting, the received acoustic energy responsive to contrast agents and the thrombosis;
second transmitting acoustic energy, with the ultrasound transducer, the transmitting being about 1.0 MI or more and operable to alter the contrast agents associated with the thrombosis. - View Dependent Claims (21, 22, 23)
