  • Patent number: 11596351
    Abstract: Disclosed herein is a non-invasive system for determining tissue composition. The system comprises an imaging system with a non-invasive probe, a signal analyzer, and a correlation processor. The probe includes active imaging components for emitting energy and collecting imaging data including reflected signals from an object of interest. The signal analyzer analyzes the imaging data and determines one or more signal properties from the reflected signals. The correlation processor then associates the one or more signal properties to pre-determined tissue signal properties of different tissue components through a pattern recognition technique wherein the pre-determined tissue signal properties are embodied in a database, and identifies a tissue component of the object based on the pattern recognition technique.

  • Publication number: 20220139561
    Abstract: Using a patient's physiological parameters ascertained using standard intravascular ultrasound (IVUS) in combination with virtual histology (VH), these physiological parameters are evaluated to predict whether the patient's physiology has an increased risk of producing a Clinical Event or a Silent Clinical Event. In one embodiment the following three physiological parameters: the Plaque Burden; the Minimum Lumen Area; and whether a VH-TCFA or multiple VH-TCFAs are present are compared to target values and ranges. A concurrence of the values for the physiological parameters falling within the target ranges indicates that a patient's physiology has an increased risk of producing a Clinical Event or a Silent Clinical Event, respectively. In other embodiments, combinations of any two of the three physiological parameters listed above are compared to target values and ranges.
