Problems solved by technology

Localization of ICE can be a difficult task as the coronary arteries may not always be visible in the image and as Doppler recordings require an appropriate angle relative to blood flow

Embodiment Construction

[0048] figure 1 An image 1 of the region of the heart presenting the coronary arteries 3 is shown. The heart chambers 5 are visible in image 1 . Within image 1 a region of interest (ROI) 7 is provided. The ICE probe 9 is located within the heart chamber 5 providing the US imaging cone 11 .

[0049] The features, functions and properties described above with respect to methods, devices and systems also apply to figure 1 The features shown and described will not be repeated.

[0050] figure 2 A flowchart is shown of a method of providing a guided measure allowing optimal intracardiac placement of an ICE probe within an image for imaging, for example, a ROI comprising a coronary circulation.

[0051] Acquire images of the S1 cardiac region. The image provides at least one or more coronary vessels and / or at least one chamber of the heart. Define S2 at least one ROI within the image. At least one of position, orientation or access path of the ICE probe relative to the ROI ...

Abstract

The present invention relates to an intra cardiac echo imaging device, an intra cardiac echo imaging system and method for assessing coronary circulation using an intra cardiac echo probe. An image ofa cardiac region is received, wherein the image provides at least one or more coronary vessels and / or at least one heart chamber; at least one region of interest within the image is defined; imagingparameters of an intra cardiac echo probe are received; and at least one of a location, an orientation and access path of the intra cardiac echo probe relative to the region of interest is calculatedbased on: anatomical content in the region of interest and / or in the cardiac region and the imaging parameters of the intra cardiac echo probe; a roadmap and the at least one of the calculated location, orientation and access path of the intra cardiac echo probe is output to a display.

Description

technical field [0001] The invention relates to an intracardiac echo imaging device, an intracardiac echo imaging system, a method for evaluating the coronary circulation using an intracardiac echo probe, as well as a corresponding computer program element and a computer readable medium. Background technique [0002] An intracardiac echo (ICE) probe or catheter allows recording of ultrasound images from inside the chambers of the heart. For electrophysiological (EP) procedures like cardiac ablation or resynchronization of therapeutic aortic blood flow, the pulmonary annulus, ventricular or atrial lining, or other structures are imaged from within the heart. Furthermore, the ICE probe can be used to record Doppler ultrasound (US) images of the coronary arteries of the patient's heart. Such Doppler images allow the derivation of coronary blood flow, which is often considered an important measure for the diagnosis and treatment of coronary artery disease. [0003] WO 2008 / 067...
