摘要： A method for assisting the planning of an interventional biventricular pacing procedure includes segmenting an image dataset of a heart of a patient to extract a surface of a left ventricle (LV) and a LV myocardium of the patient's heart, utilizing the segmented image dataset to divide the LV into myocardial segments or into a plurality of short axis slices, and detecting wall motion of each short axis slice of phases of a cardiac cycle of the patient's heart with respect to a reference phase. The method also includes localizing a region most recently attaining maximum displacement and a region most recently attaining maximum velocity, and generating 2D or 3D renderings including renderings indicating at least one of time delays of contraction, a maximum displacement, or a maximum velocity.

摘要： A method of cardiac radiological examination for coronarography comprises the steps of: a) introducing contrast medium simultaneously in the left coronary artery and in the right coronary artery from the aortic root and, in parallel, b) acquiring a sequence of dynamic images of the propagation of the contrast medium in the left and right coronary arteries with a displacement of the image plane, during the acquisition of said images, along a determined trajectory (E28). The contrast medium can be introduced in a cyclic manner during the acquisition of dynamic images, each cycle of introduction corresponding to a phase of closure of the aortic valve in the cardiac rhythm. 3D and 4D images with optimal efficiency can be obtained in the use of contrast medium. An injection device for producing the above cycles is synchronized with the introduction of the contrast medium.

摘要： A method for selecting and/or labeling a vessel image includes operating an imaging system to obtain reconstructed image data including a volume having vessels therein. A bone removal routine is then applied to the reconstructed image data to produce a bone-free image. An initial point on a main vessel in the bone-free image is located, and bifurcation points and branches departing from the main vessel are identified. An adjacency graph of each branch coming from the main vessel is built. The method includes either or both of selecting and displaying a best or at least a favorable path through the vessels in accordance with predetermined criteria using the adjacency branch, or labeling and displaying branches of the main vessel.
