Abstract
An integrated electrophysiology and ultrasound imaging system includes a workstation, electrophysiology processing circuits, a compact ultrasound imaging system having a combination of an isolation circuit, an ultrasound signal generator, and a beam former within a single unit. The integrated workstation provides a single control interface and data display for the electrophysiology and ultrasound imaging subsystems. Integrating the control of electrophysiology and ultrasound imaging equipment within a single workstation reduces clinician workload.
