Appl. No.:

09/645872

Assignee:

Kininklijke Philips Electronics N.V. - Eindhoven

International Classification:

A61B 800

US Classification:

600443, 600458

Abstract:

An ultrasonic imaging method and apparatus are described for imaging the coronary arteries of the heart. The vascular system is infused with an ultrasonic contrast agent. A volumetric region of the heart wall including a coronary artery is three dimensionally scanned. A projection image of the volumetric region is produced from the scanning, providing a two dimensional contrast image of the coronary artery with the appearance of an angiogram. Preferably the coronary artery signals are segmented from contrast signals emanating from the myocardium and the heart blood pool so that the coronary arteries are clearly highlighted and distinct in the ultrasonic angiogram.

Inventors:

Rohit Garg - Seattle WA
Edward A. Miller - Everett WA
Damien Dolimier - Bothell WA
Danny M. Skyba - Bothell WA

Assignee:

Koninklijke Philips Electronics N.V. - Eindhoven

International Classification:

A61B 800

US Classification:

600443

Abstract:

A system and method are provided for simplifying off-line quantification of ultrasound images by displaying a graphical user interface showing a real-time ultrasound image for enabling a user to freeze the real-time ultrasound image to display an image sequence capable of being modified and played back by the user. Upon freezing the real-time image, the graphical user interface displays a tagging system having a corresponding identification tag for each ultrasound image of the image sequence. The graphical user interface further displays time intensity curves each corresponding to an ROI in the frozen image. When the user selects a particular ROI in the frozen image, the curve corresponding to the selected ROI is brightened and the other curves are dimmed.

International Classification:

A61B 800

US Classification:

600440, 600458

Abstract:

A method and system for displaying a parametric image showing tissue perfusion includes an ultrasonic imaging system coupled to an ECG device. The ECG device triggers the imaging system to obtain contrast image data showing tissue perfusion at a respective predetermined time during each of a plurality of heartbeats. Parametric image data for discrete locations in the area of interest such as the myocardium is determined from the temporal contrast data acquired during reperfusion of the tissue in the area of interest. The parameters are mapped to a display value such as color to produce a parametric perfusion ultrasound image. Sequences of images may be produced which depict both perfusion characteristics and dynamic wall motion of the myocardium in a common image sequence.

International Classification:

G06K 9/00

US Classification:

382128

Abstract:

A system and method are provided for simplifying off-line quantification of ultrasound images by displaying a graphical user interface showing a real-time ultrasound image for enabling a user to freeze the real-time ultrasound image to display an image sequence capable of being modified and played back by the user. The graphical user interface displays graphs or curves providing data related to the ultrasound images. Each data point on the curves represents one ultrasound image of the ultrasound images. When the user selects a particular data point on a curve of a graph, the corresponding ultrasound image is displayed by the graphical user interface. The user can then select another data point on the same curve or another curve to display another corresponding ultrasound image. The two ultrasound image framescan then be compared. The system and method of the present invention further provide the ability for a user to select a region of interest within one of the displayed images to display parameters associated with the selected region of interest for the two ultrasound images.
