摘要： An ultrasound system that detects a characteristic of an ultrasound wave. The system includes a circuit member defining a sensing portion operable to be exposed to the ultrasound wave. The system also includes a current generating device that generates a current in the sensing portion of the circuit member. Furthermore, the system includes a voltage sensor that detects a voltage across the sensing portion due to the exposure to the ultrasound wave to thereby detect the characteristic of the ultrasound wave.

摘要： 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.

摘要： Devices are disclosed for obtaining data of a sample, particularly data capable of being processed to produce an image of a region of the sample. An exemplary device includes a light-beam source, an acoustic-wave source, an optical element, and an acoustic detector. The optical element is transmissive to a light beam produced by the light-beam source and reflective to acoustic waves produced by the acoustic-wave source. The optical element is situated to direct the transmitted light beam and reflected acoustic wave simultaneously along an optical axis to be incident at a situs in or on a sample to cause the sample to produce acoustic echoes from the incident acoustic waves while also producing photoacoustic waves from the incident light beam photoacoustically interacting with the situs. The acoustic detector is placed to receive and detect the acoustic echoes and the photoacoustic waves from the situs. The acoustic detector can comprise one or more hydrophones exploiting the acousto-electric effect.
