Publication number: 20080114253Abstract: The disclosed embodiments include a method, system, and device for conducting ultrasound interrogation of a medium. The novel method includes transmitting a non-beamformed or beamformed ultrasound wave into the medium, receiving more than one echoed ultrasound wave from the medium, and converting the received echoed ultrasound wave into digital data. The novel method may further transmit the digital data. In some embodiments, the transmitting may be wireless. The novel device may include transducer elements, an analog-to-digital converter in communication with the transducer elements, and a transmitter in communication with the analog-to-digital converter. The transducers may operate to convert a first electrical energy into an ultrasound wave. The first electrical energy may or may not be beamformed. The transducers also may convert an echoed ultrasound wave into a second electrical energy.Type: ApplicationFiled: November 10, 2006Publication date: May 15, 2008Applicant: Penrith CorporationInventors: Kevin S.

Patent number: 6561979Abstract: A portable medical diagnostic ultrasound system is provided which includes shielding for electromagnetic interference by forming shielded enclosed compartments around the individual components of the ultrasound system. This compartmentalization of components isolates EMI between the components themselves as well as the outside world. Further, the EMI shielding provides structural rigidity and support for the entire ultrasound system. In another aspect, the EMI shielding provides heat dissipation capability for the internal components of the ultrasound system. The portable medical diagnostic ultrasound system further provides a transducer connector which provides high density interconnects between the transducer and the ultrasound system while providing an ergonomically easy to handle connector. Further, the connector is rugged, providing a high number of connection and disconnection cycles.Type: GrantFiled: September 14, 1999Date of Patent: May 13, 2003Assignee: Acuson CorporationInventors: Andrew J.

Patent number: 6524244Abstract: The preferred embodiments described herein provide a medical diagnostic ultrasound imaging system and method in which a non-real-time operating system is used to transfer image data. In one preferred embodiment, a medical diagnostic ultrasound imaging system includes a central processing unit (“CPU”) located outside of the received signal path to transfer image data. The non-real-time operating system can be used, for example, to transfer image data from a hard disk to system memory for display, to transfer image data from system memory to the hard disk for storage, or to scroll image data to view a loop of image data.Type: GrantFiled: September 14, 1999Date of Patent: February 25, 2003Assignee: Ecton Inc.Inventors: Christopher B.

Patent number: 6508763Abstract: The preferred embodiments described herein relate to a medical diagnostic ultrasound imaging system with at least one reprogrammable logic device, such as, for example, a field programmable gate array (“FPGA”). In one presently preferred embodiment, at least one reprogrammable logic device in the ultrasound system is reconfigured for probe changes (e.g., phased-array, curved array), for operator control changes (such as system mode changes, e.g., B-Mode, color Doppler), and/or dynamically as part of system operation (such as between ultrasonic pulse firings and/or between frames). By utilizing at least one reprogrammable logic device, the preferred embodiments reduce the size and cost of the ultrasound system without compromising the performance characteristics of the system.Type: GrantFiled: September 14, 1999Date of Patent: January 21, 2003Assignee: Ecton, Inc.Inventors: Joseph A.

Patent number: 6312381Abstract: A diagnostic ultrasound system and method for providing temporally accurate EKG data with imaging is provided. The EKG data is linked to imaging data. The frame of data of imaging data contains EKG data in a line of information. Additional EKG data may be provided separately from the imaging data. A scan converter processes both the EKG data and imaging data at substantially the same time, maintaining temporal accuracy. The EKG data provided comprises an entire trace so that the trace on the display appears to be smoothly updated.Type: GrantFiled: September 14, 1999Date of Patent: November 6, 2001Assignee: Acuson CorporationInventors: Christopher B.

Patent number: 6228030Abstract: A scheme is provided for locating the time of occurrence of a predetermined event in a physiologic cycle associated with an anatomical object of a subject's body. Echoes produced from transmission of ultrasound energy into the anatomical object are processed by an image frame acquisition device to produce a series of image frames. Each image frame includes data representing an image of at least a portion of the anatomical object at a given time. Then, the difference is determined between the current image frame and at least one preceding image frame. A frame correlation coefficient is output based upon the difference. The time of occurrence is located at the instance of time when the frame correlation coefficient falls below a predetermined value, or when the rate of change of the frame correlation coefficient exceeds a predetermined value. The physiologic cycle may be the heart cycle and the predetermined event may be the QRS trigger of an electrocardiogram.Type: GrantFiled: August 27, 1999Date of Patent: May 8, 2001Assignee: Ecton, Inc.Inventors: Joseph A. Urbano, Christopher B. Knell, Kevin S. Randall, Andrew J. Wood

Patent number: 6086537Abstract: Speckle is reduced in full motion ultrasound image data representing anatomic structures which have periodic physiological motion. Echoes produced from transmission of ultrasound energy into a subject's body are processed by an image frame acquisition device to produce a series of image frames for each physiologic cycle. Each image frame comprises data representing an image of a portion of the subject's body at a given time within the cycle. Successive image frames obtained at the same point in time within each physiologic cycle are filtered. The filtering is applied to each image frame within the entire current physiologic cycle, thereby deriving full motion speckle-reduced image data.Type: GrantFiled: March 4, 1999Date of Patent: July 11, 2000Assignee: Ecton, Inc.Inventors: Joseph A. Urbano, Christopher B. Knell, Kevin S. Randall, Andrew J. Wood
