Patent number: 10987086Abstract: An intravascular ultrasound imaging system comprises a catheter having an elongated body having a distal end and an imaging core arranged to be inserted into the elongated body. The imaging core is arranged to transmit ultrasonic energy pulses and to receive reflected ultrasonic energy pulses. The system further includes an imaging engine coupled to the imaging core and arranged to provide the imaging core with energy pulses to cause the imaging core to transmit the ultrasonic energy pulses. The energy pulses are arranged in repeated sequences and the energy pulses of each sequence have varying characteristics. The reflected pulses may be processed to provide a composite image of images resulting from each different characteristic.Type: GrantFiled: October 5, 2017Date of Patent: April 27, 2021Assignee: ACIST Medical Systems, Inc.Inventors: Thomas C. Moore, Kendall R. Waters, J. Steve Reynolds, Duc H. Lam, Donald Masters

Patent number: 10134132Abstract: An intravascular imaging system includes a transducer capable of generating raw data representative of the structure of a patient's vasculature. The system includes an imaging engine for receiving the raw data and generating enhanced data for presentation to a user. The imaging engine includes a coherence filter, an envelope detection module having one or more envelope detectors, and a spatial filter for processing data in various stages. Such stages of processing in the imaging engine act to reduce high frequency noise, generate low frequency data, reduce low frequency noise, and display low frequency data with an improved signal-to-noise ratio. The system can include an image generator for generating an image based on enhanced data and a display for displaying the generated image.Type: GrantFiled: June 6, 2017Date of Patent: November 20, 2018Assignee: ACIST MEDICAL SYSTEMS, INC.Inventors: Duc Lam, J Steve Reynolds

Patent number: 5885218Abstract: A spatial filtering method and apparatus which is particularly useful for addressing the problem of pulsation motion in intravascular ultrasound imaging, but may also be applied to imaging systems in other environments. According to a specific embodiment, the present invention provides a method and related apparatus for determining relative motion (rotation, pulsation, or in-plane translation and/or a combination thereof) in orthogonal r-.theta. memory space, prior to scan conversion, between a first and second image frame, and displaying an accurate image and/or performing pre-scan conversion image stabilization of the image.Type: GrantFiled: November 7, 1997Date of Patent: March 23, 1999Assignees: SciMed Life Systems, Inc., Boston Scientific LimitedInventors: Tat-Jin Teo, J.
