| Title: | HIGH-RESOLUTION MAPPING OF BIO-ELECTRIC FIELDS | |||||||||||
| Abstract: | A current source density mapping system includes an ultrasound transducer emitting an ultrasound wave traveling along an ultrasound beam directed at a mapping field in a region of living tissue and an ultrasound pulser delivering a transmit pulse to said ultrasound transducer. The system includes a timing device producing controlled excitation of the transmit pulse; a plurality of recording electrodes positioned in contact with the living tissue detecting an acoustoelectric voltage signal generated at a bioelectric current source and within a focal zone of said ultrasound beam. An amplifier operatively connected to the recording electrodes amplifying the acoustoelectric voltage signal at a predetermined gain; and an analyzing component comprising a digitizer, a sampling device, a signal processor and a display unit operatively connected to the amplifier determining the location of the bioelectric current source by analyzing the acoustoelectric voltage signal detected by the recording electrodes in response to an interaction between the ultrasound wave and the presence of a current source in the mapping field. | |||||||||||
