A reset device of the present invention includes a microprocessor-based controller and associated programming for operating the reset device. As part of the automatic reset process, a reset device of the present invention is able to perform the connector pin jumpering necessary to resetting many encoders. Methods and systems for passively detecting stable cavitation and enhancing stable cavitation during sonothrombolysis are provided. The method of passively detecting stable cavitation includes providing a determined level of ultrasonic energy and detecting a scattered level of ultrasonic energy. The system for inducing and passively detecting stable cavitation includes a dual-element annular transducer array configured to provide a fundamental ultrasonic frequency and to detect an ultrasonic frequency that is a derivative of the fundamental frequency. The method of enhancing stable cavitation includes administering a nucleating agent and a thrombolytic agent to a treatment zone, providing a determined level of ultrasonic energy, and detecting a scattered level of ultrasonic energy.</p> |
