摘要： Projection data (302) acquired during a tomographic examination of a periodically moving object is used to reconstruct a plurality of image layers (308). The image layers (308) are combined to generate image data at a desired phase of motion. To generate a weighting function used to combine the image layers, a reference weighting function (512) is generated at the desired phase. The image layers (308) are weighted to approximate the first weighting function (312). The number of image layers and the size of a sub-region of interest are advantageously selected so that the various image layers can be stored in a relatively high speed memory portion of a computer.

摘要： A coronary arteries tree is approximated by a base sphere (32) which is best fitted to vessels centerlines (38). The base surface (32) is gridded to define pixels (52). The base sphere (32) is mapped to fit the centerlines (38) such that a true form surface (56) is determined. A wall thickness to the true form surface (56) is defined, preferably, by a user. A normal of each pixel (52) is searched for grayscale values of voxels. Each pixel (52) is assigned a maximum of grayscale values of voxels within the defined wall thickness intersected by the corresponding normal. The resulting true form surface is undistorted mode of visualization revealing the arteries tree in its context running on the true surface drawn through the vessels. Mapping the assigned grayscale values onto the base sphere (32) visualizes arteries tree on a globe surface (84) which might be rotatably inspected as a globe. Mapping the assigned grayscale values into a flat surface visualizes arteries tree on a two-dimensional map.

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.
