摘要： A method for visualizing a region of interest within a viewport includes presenting tomographic image data as an image in a viewport using a set of global image processing operations, presenting a viewing window in the main viewport; and using a second, different set of image processing operations that is local to the viewing window, wherein the second, different set of image processing operations reduces image artifact with respect to a desired structure of interest in the viewing window.

摘要： A computed tomography system (100) includes a windowing component (140) that receives an ECG signal that includes a premature heart cycle. The ECG signal is time-synchronized with x-ray projection data of a beating heart. The windowing component (140) either removes or repositions a first reconstruction window within a first heart cycle to correspond to a desired cardiac phase when the premature heart cycle causes the first reconstruction window to correspond to a different cardiac phase, based on available data. A reconstructor (148) that reconstructs projection data corresponding to a plurality of reconstruction windows from different cardiac cycles generates image data indicative of the desired phase of the heart.

摘要： A method for performing a medical procedure is provided, including recording geometric information at a plurality of time points in a plurality of cardiac cycles of a heart of a subject. Subsequently, a transient event is detected that is produced at a location on the heart during a cardiac cycle. A time of occurrence of the transient event is identified in the cardiac cycle during which the transient event occurred. A map of the heart is displayed responsive to the identified time of occurrence and the geometric information recorded at a time point in the cardiac cycle that corresponds to the time of occurrence of the transient event.

摘要： A diagnostic imaging apparatus generates a three-dimensional diagnostic image representation. The image representation is converted into an image representation of the patient's heart. A left lower posterior point of the heart image representation is selected as a first approximation of a left ventricle apex and a line of preselected orientation is drawn through the first approximation apex as a first approximation ventricle axis. The ventricle axis is redefined by generating short axis slices across the approximated ventricle axis, isolating a selected one of the ventricles, determining a centroid of each short axis slice of the selected ventricle, and fitting the axis to the apex approximation and the centroids. The apex location is redefined by looking for the lowermost short axis slice orthogonal to the redefined axis which intersects the ventricle volume and selecting the intersection point as the next approximation of the apex. The axis and apex redefining are iteratively repeated to determine the ventricle axis and apex automatically.

摘要： A diagnostic imaging system (10) images overlapping cyclically moving and stationary regions of a subject. A low resolution reconstruction processor (50) reconstructs acquired data into a series of consecutive low resolution volumetric image representations. A motion region determining processor (70) determines a boundary of the moving region from the consecutive low resolution volumetric image representations. A high resolution reconstruction processor (60) reconstructs the acquired data into a high resolution volumetric image representation. A stationary region removing processor (84) removes stationary region image data from the high resolution volumetric image representation, which stationary region image data lies exterior to the moving region boundary. A display (86) displays the high resolution volumetric image representation.
