    Abstract: Monitoring intracardiac ablation progress in near real time is accomplished by evaluating capture of a pacing signal while ablation energy is concurrently directed to a target site. Sufficiency of ablation is indicated by failure of signal capture at a maximum predetermined pacing voltage. A common electrode in a cardiac catheter is simultaneously used to test pacing capture and to deliver ablation energy.

    Abstract: A medical imaging system for imaging a patient's body includes a catheter having a position sensor and an ultrasonic imaging sensor wherein the position sensor transmits electrical signals indicative of positional information of a portion of the catheter in a patient's body and the ultrasonic imaging sensor transmits ultrasonic energy at a target in the patient's body, receives ultrasonic echoes reflected from the target in the patient's body and transmits signals relating to the ultrasonic echoes reflected from the target in the patient's body. A positioning processor is operatively connected to the catheter for determining positional information of the portion of the catheter based on the electrical signals transmitted by the position sensor. The system also includes a display and an image processor operatively connected to the catheter, the positioning processor and the display. The image processor generates an ultrasonic image of the target based on the signals transmitted by the ultrasonic sensor and depicts in real-time the generated ultrasound image on a display in a same orientation as an orientation of the portion of the catheter in the patient's body based on positional information derived from the position sensor.

    Abstract: A method for position sensing includes placing at a known position within a body of a subject a reference probe including at least one reference electrode. Electrical currents are passed through the body between the reference electrode and body surface electrodes. Characteristics of the electrical currents are measured and are used to generate an approximation of the known position of the reference probe. A correction factor is determined based on a relationship between the approximation and the known position. A target probe including at least one target electrode is placed within the body of the subject and second electrical currents are passed through the body between the target electrode and the body surface electrodes. Characteristics of the second electrical currents are measured and used to generate a calculated position of the target probe. The correction factor is applied to correct the calculated position.
