Patent number: 11536817Abstract: A system and method from improving the image quality achievable with an ultrasound transducer by using a composite aperture for receiving ultrasound echoes. By using two receive cycles per vector, twice as many transducers may be used for receiving ultrasound imaging data than there are physical channels available in the ultrasound probe. An ultrasound probe utilizing a composite aperture can achieve high image quality from a system have reduced power, size, cost and complexity.Type: GrantFiled: October 26, 2020Date of Patent: December 27, 2022Assignee: INTERSON CORPORATIONInventors: Roman Solek, Patrice Richard, Albert Lee

Patent number: 11364010Abstract: A portable ultrasonic imaging probe that is adapted to connect to a host computer via a passive interface cable. The probe includes an array of ultrasound transducers, a high voltage pulser for energizing transducers to emit an ultrasound pulse, analog signal processing circuitry that combines echoes detected by transducers into a single analog echo signal, am analog-to-digital converter that converts the analog echo signal into a digital echo signal; and interface circuitry that transfers the digital echo signal across the passive interface cable to the host computer.Type: GrantFiled: November 22, 2019Date of Patent: June 21, 2022Assignee: INTERSON CORPORATIONInventor: Roman Solek

Publication number: 20140031693Abstract: The invention provides a portable ultrasonic imaging probe directly connectable to an off-the-shelf laptop computer. The probe produces raw digitized data comprising envelope detected ultrasound echo data from an array of ultrasound transducers, and transmits the data to the host computer thereby enabling the host computer to form real-time ultrasonic images of human tissue without the need for any additional electronics. In particular embodiments, the probe includes a plurality of transmit switches configured to connect a transmitting group of the ultrasound transducers to a pulser; a plurality of receive switches configured to connect a receiving group of the ultrasound transducers to analog summing, amplification and signal processing circuitry; and a transmit/receive controller which selects which of said ultrasound transducers are in the transmitting group and which of said ultrasound transducers are in the receiving group.Type: ApplicationFiled: July 26, 2013Publication date: January 30, 2014Applicant: Interson CorporationInventor: Roman Solek

Publication number: 20090051121Abstract: An encapsulated rotary seal around a rotating shaft, the seal having an outer annular body and an inner annular body. The inner annular body engages the rotating shaft and permits free rotation of the shaft while providing a liquid tight seal around the rotating shaft. The outer annular body is moulded about and permanently adhered to the inner annular body, the outer annular body permitting limited non-concentric or eccentric movement of the rotating shaft engaged to the inner annular body without affecting the integrity of the seal between the rotating shaft and the inner annular body.Type: ApplicationFiled: August 6, 2008Publication date: February 26, 2009Applicant: Interson CorporationInventors: Roman Solek, Donald Coulthart
