Abstract
A method and system for forming an ultrasound image of a tissue while simultaneously ablating the tissue in which the application of therapy current is sequenced with at least the ultrasonic detection phase of the ultrasonic visualization process. In this way, no ultrasonic detection takes place while therapy current passes, and no therapy current passes while ultrasonic detection takes place. The sequencing can take place using a communication protocol between a therapy system controlling the application of therapy current and an ultrasonic imaging system controlling the ultrasonic visualization process. Depending on the communication protocol used, the therapy system and the ultrasonic imaging system can handoff control to one another or one system can have exclusive control over the other.
