Abstract
An ultrasound system for continuous imaging and for controlling release of an encapsulated agent from a carrier comprises a housing secured to a patient's body, a transducer mounted within the housing, means for controlling the transducer to insonify the drug carrier with an ultrasonic signal and to thereby cause the release of the agent, and means for processing an ultrasonic echo signal to produce an image. Also, a method for controlling release of an encapsulated agent from a carrier comprises the steps of measuring a physiological parameter of a patient based on an ultrasonic echo signal, comparing the physiological parameter to a threshold, and transmitting an ultrasonic signal to insonify the carrier and thereby cause the release of the agent from the carrier in accord with the measured physiological parameter.
