Patent number: 9510806Abstract: 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.Type: GrantFiled: March 13, 2014Date of Patent: December 6, 2016Assignee: MAUI IMAGING, INC.Inventors: David M.

Publication number: 20160135783Abstract: 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.Type: ApplicationFiled: January 25, 2016Publication date: May 19, 2016Inventors: Kenneth D. BREWER, David M.

Patent number: 9192355Abstract: 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.Type: GrantFiled: May 14, 2013Date of Patent: November 24, 2015Assignee: MAUI IMAGING, INC.Inventors: David M.

Publication number: 20150045668Abstract: A Multiple Aperture Ultrasound Imaging (MAUI) probe or transducer is uniquely capable of simultaneous imaging of a region of interest from separate physical apertures. Construction of probes can vary by medical application. That is, a general radiology probe can contain multiple transducers that maintain separate physical points of contact with the patient's skin, allowing multiple physical apertures. A cardiac probe may contain only two transmitters and receivers where the probe fits simultaneously between two or more intracostal spaces. An intracavity version of the probe can space transmit and receive transducers along the length of the wand, while an intravenous version can allow transducers to be located on the distal length the catheter and separated by mere millimeters. Algorithms can solve for variations in tissue speed of sound, thus allowing the probe apparatus to be used virtually anywhere in or on the body.Type: ApplicationFiled: October 28, 2014Publication date: February 12, 2015Inventors: David M.
