Filed:

Apr 23, 2001

Appl. No.:

09/840591

Inventors:

Sorin Grunwald - Santa Clara CA

Assignee:

SciMed Life Systems, Inc. - Maple Grove MN

International Classification:

A61B 800

US Classification:

600437, 600443

Abstract:

According to the invention, an object in an ultrasound image is characterized by considering various in-vivo object parameters and their variability within the ultrasonic imaging data. Specifically, it is assumed that the object may be defined in terms of statistical properties (or object identifying parameters), which are consistently different from properties of the environment. Such properties are referred to as the objects signature. The statistical properties are calculated at selected locations within the image to determine if they fall within a predetermined range of values which represents the object. If within the range, the locations are marked to indicate they are positioned within the object. A border may then be drawn around the object and the area calculated.

International Classification:

A61B 0800

US Classification:

600462, 600437, 600455

Abstract:

In an intravascular ultrasonic (IVUS) imaging system ring-down artifact is reduced or eliminated by dynamically enhancing the ring-down over a plurality of scans, determining the ring-down range by keying on a ring-down-to-blood transition characterized by a rapid change from high amplitude to low amplitude echoes, and using a spectral pattern for a single or several A-scans within the ring-down range, using for example an FFT analysis, as the basis of selectively filtering current or subsequent images using the recently computed ring-down pattern.

International Classification:

A61B 8/14

US Classification:

600446

Abstract:

A Graphical User Interface (GUI) for an ultrasound system. The ultrasound system has operational modes and the GUI has corresponding icons, tabs, and menu items image and information fields. The User Interface (UI) provides several types of graphical elements with intelligent behavior, such as being context sensitive and adaptive, called active objects, for example, tabs, menus, icons, windows of user interaction and data display and an alphanumeric keyboard. In addition the UI may also be voice activated. The UI further provides for a touchscreen for direct selection of displayed active objects. In an embodiment, the UI is for a medical ultrasound handheld imaging instrument. The UI provides a limited set of hard and soft keys with adaptive functionality that can be used with only one hand and potentially with only one thumb.

International Classification:

A61B 8/14

US Classification:

600468

Abstract:

The invention relates to the guidance, positioning and placement confirmation of intravascular devices, such as catheters, stylets, guidewires and other flexible elongate bodies that are typically inserted percutaneously into the venous or arterial vasculature. An aspect of the invention includes, for example, an endovenous access and guidance system. The system comprises: an elongate flexible member adapted and configured to access the venous vasculature of a patient; a sensor disposed at a distal end of the elongate flexible member and configured to provide in vivo non-image based ultrasound information of the venous vasculature of the patient; a processor configured to receive and process in vivo non-image based ultrasound information of the venous vasculature of the patient provided by the sensor and to provide position information regarding the position of the distal end of the elongate flexible member within the venous vasculature of the patient; and an output device adapted to output the position information from the processor.

International Classification:

A61B 8/06

US Classification:

600468

Abstract:

An endovascular access and guidance system has an elongate body with a proximal end and a distal end; a non-imaging ultrasound transducer on the elongate body configured to provide in vivo non-image based ultrasound information of the vasculature of the patient; an endovascular electrogram lead on the elongate body in a position that, when the elongate body is in the vasculature, the endovascular electrogram lead electrical sensing segment provides an in vivo electrogram signal of the patient; a processor configured to receive and process a signal from the non-imaging ultrasound transducer and a signal from the endovascular electrogram lead; and an output device configured to display a result of information processed by the processor.
