Abstract: Sparse arrays of transducer elements may be beneficial in providing ultrasound transducer probes with a wide total aperture while containing a manageable number of transducer elements. Sparse arrays made with bulk piezoelectric materials or with arrays of micro-elements can be effectively with ping-based multiple aperture ultrasound imaging techniques to perform real-time volumetric imaging.

Abstract: The effective aperture of an ultrasound imaging probe can be increased by including more than one transducer array and using the transducer elements of all of the arrays to render an image can greatly improve the lateral resolution of the generated image. In order to render an image, the relative positions of all of the elements must be known precisely. Systems and methods for accurately calibrating and adjusting a multi-aperture ultrasound system are disclosed. The relative positions of the transducer elements can be computed and aligned prior to and during probe assembly.

Abstract: A method for fuel quantity gauging that measures the quantity of liquid fuel in a fuel tank directly without the need to accurately locate fuel heights throughout the fuel tank using multiple fuel gauging probes. The method may comprise the following steps performed while fuel is flowing out of the fuel tank: (a) changing a volume of gas in the fuel tank (e.g., by injecting or venting gas) during a time interval; (b) measuring a rate of change of the volume of gas in the fuel tank during the time interval; (c) measuring a rate of flow of fuel out of the fuel tank during the time interval; (d) measuring a first pressure and a first temperature of the gas in the fuel tank at the start of the time interval; (e) measuring a second pressure and a second temperature of the gas in the fuel tank at the end of the time interval; and (f) calculating a quantity of fuel in the fuel tank based on the measurement data acquired in steps (c) through (f). Step (f) is performed by a processing unit.

Abstract: Systems and methods of M-mode ultrasound imaging allows for M-mode imaging along user-defined paths. In various embodiments, the user-defined path can be a non-linear path or a curved path. In some embodiments, a system for M-mode ultrasound imaging can comprise a multi-aperture probe with at least a first transmitting aperture and a second receiving aperture. The receiving aperture can be separate from the transmitting aperture. In some embodiments, the transmitting aperture can be configured to transmit an unfocused, spherical, ultrasound ping signal into a region of interest. The user-defined path can define a structure of interest within the region of interest.

Abstract: Increasing the effective aperture of an ultrasound imaging probe by including more than one probe head and using the elements of all of the probes to render an image can greatly improve the lateral resolution of the generated image. In order to render an image, the relative positions of all of the elements must be known precisely. A calibration fixture is described in which the probe assembly to be calibrated is placed above a test block and transmits ultrasonic pulses through the test block to an ultrasonic sensor. As the ultrasonic pulses are transmitted though some or all of the elements in the probe to be tested, the differential transit times of arrival of the waveform are measured precisely. From these measurements the relative positions of the probe elements can be computed and the probe can be aligned.
