Patent number: 7984651Abstract: 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: GrantFiled: November 10, 2006Date of Patent: July 26, 2011Assignee: Penrith CorporationInventors: Kevin S. Randall, Jodi Schwartz Klessel, Anthony P. Lannutti, Joseph A. Urbano

Publication number: 20100286527Abstract: An ultrasound system and method is described in which a probe is used in conjunction with a main unit. The probe contains at least two different transducer or transducer array types to provide an operator with a selection of transducer types for use without having to change to a different probe. Transducer types may include wide-band and narrow band transducers or transducer arrays within a single probe, and may be selected for use by a selector switch on the probe. Data collected by the probe during operation may be transmitted wirelessly back to a main unit through the use of a wireless antenna incorporated into the probe. In addition, one of the transducers at either end of the probe may be replaced by an adjunct equipment type such as a stethoscope.Type: ApplicationFiled: May 8, 2009Publication date: November 11, 2010Applicant: Penrith CorporationInventors: Michael G. Cannon, Joseph A. Urbano, Kevin S. Randall, Lawrence A. Engle

Patent number: 7678048Abstract: A medical diagnostic ultrasound system comprises several subsystems, such as a transmit beamformer, a receive beamformer, a B-mode processor, a Doppler processor and a scan converter. These subsystems are within the ultrasound data processing path for processing ultrasound data. One or more of these subsystems are implemented with one or more re-programmable logic devices. For example, one or two field programmable gate arrays are used is each subsystem to perform most or almost all of the subsystems essential functionality.Type: GrantFiled: September 14, 1999Date of Patent: March 16, 2010Assignee: Siemens Medical Solutions USA, Inc.Inventors: Joseph A. Urbano, Christopher B. Knell, Kevin S. Randall, Andrew J. Wood

Patent number: 7570112Abstract: A preamplifier has a variable input impedance. The input impedance is tailored with the signal level to maintain a more optimal performance. The input impedance is varied by at least two amplifiers connected in parallel. Each amplifier has a different input impedance. By controlling the bias currents to the amplifiers, the contribution to the input impedance of the parallel amplifiers is controlled. Gradual variation in input impedance may be obtained by gradual variation in relative contribution by the different amplifiers.Type: GrantFiled: December 15, 2005Date of Patent: August 4, 2009Assignee: Siemens Medical Solutions USA, Inc.Inventors: Kevin S. Randall, James J. Edelen, III

Publication number: 20080188752Abstract: The embodiments contemplate systems and methods for detecting moving tissue within an object. In one such method, a transducer is directed to transmit a first and second ultrasound pulse at a sample volume within a patient. The transducer receives a first and second echo signal of the first and second ultrasound pulses containing information related to the sample volume. A determination is made from the information as to the location and type of blood vessel located within the sample volume, and the located blood vessel information is processed to create an audio representation of the blood flow within the located blood vessel.Type: ApplicationFiled: February 5, 2007Publication date: August 7, 2008Applicant: Penrith CorporationInventors: Kevin S. Randall, Joseph A. Urbano, Lawrence A. Engle, Anthony P. Lannutti, Jodi Schwartz Klessel, Raymond F. Weymer, Michael G. Cannon

Publication number: 20080188747Abstract: The embodiments contemplate systems and methods for detecting moving tissue within an object. In one such method, a first and second ultrasound pulse are transmitted at a first sample volume within an object. A first echo signal of the first ultrasound pulse is received from the first sample volume and a second echo signal of the second ultrasound pulse is received from the first sample volume. An estimate of position displacement data of the first sample volume is computed from the first and second echo signals, and the estimate of position displacement data is compared to a predetermined position displacement data threshold indicative of moving tissue. A determination is made, based on the comparison, whether the first sample volume corresponds to moving tissue and, based on the determination, the transmitting, receiving, computing and determining is repeated for a second sample volume.Type: ApplicationFiled: February 5, 2007Publication date: August 7, 2008Applicant: Penrith CorporationInventors: Kevin S. Randall, Joseph A. Urbano, Lawrence A. Engle, Anthony P. Lannutti, Jodi Schwartz Klessel, Raymond F. Weymer, Michael G. Cannon
