A Multiple Aperture Ultrasound Imaging system and methods of use are provided with any number of features. In some embodiments, a multi-aperture ultrasound imaging system is configured to transmit and receive ultrasound energy to and from separate physical ultrasound apertures. In some embodiments, a transmit aperture of a multi-aperture ultrasound imaging system is configured to transmit an omni-directional unfocused ultrasound waveform approximating a first point source through a target region. In some embodiments, the ultrasound energy is received with a single receiving aperture. In other embodiments, the ultrasound energy is received with multiple receiving apertures. Algorithms are described that can combine echoes received by one or more receiving apertures to form high resolution ultrasound images. Additional algorithms can solve for variations in tissue speed of sound, thus allowing the ultrasound system to be used virtually anywhere in or on the body.

An ultrasonic device includes a driving circuit to provide drive power, a first transducer array to generate ultrasonic waves, the first transducer array being connected to receive power from the driving circuit, and a second transducer array to detect reflected or elicited ultrasonic waves incident on the device from a target and generate a signal based on those waves, the second transducer array being acoustically transmissive and disposed over the first transducer array such that the generated ultrasonic waves pass through the second transducer array. The second array is tuned to operate on top of the first. The functions of the two arrays may be reversed and the array tuned to operate with the first array receiving and the second array transmitting.
