    摘要： An imaging apparatus for imaging an object includes a geometric relation determination unit configured to determine a geometric relation between first and second images of the object. A marker determination unit configured to determine corresponding marker locations in the first and second images and marker appearances based on the geometric relation such that the marker appearances of a first marker to be located at a first location in the first image and of a second marker to be located at a second corresponding location in the second image are indicative of the geometric relation. The images with the markers at the respective corresponding locations are shown on a display unit. Since the marker appearances are indicative of the geometric relation between the images, a comparative reviewing of the images can be facilitated, in particular, if they correspond to different viewing geometries.

    摘要： A system (100) and method are provided for determining an effective cross-sectional area of a tubular cardiovascular structure (400), which may be used in the assessment of blood flow through the tubular cardiovascular structure. Said determining comprises obtaining a three-dimensional Image'of the tubular cardiovascular structure, segmenting the image to obtain a segmentation of the lumen inside the tubular cardiovascular structure, and determining a centerline (430) of the tubular cardiovascular structure. Then, using the segmentation of the lumen, an apparent flow aperture of the tubular cardiovascular structure is determined in the direction of the centerline, e.g., by projecting the segmentation along the direction of the centerline and determining the area in the projection which is free of projected parts. In contrast to area planimetry, the apparent flow aperture does not overestimate the effective cross-sectional area of the tubular cardiovascular structure, and thus may be used to provide a better estimate of the effective cross-sectional area of said cardiovascular structure.
