The invention relates to a position determining device for determining a position of an elongate object within a tubular structure, said position determining device comprising a first providing unit for providing a first distribution of curvature values at a plurality of first points along a path within the tubular structure. The position determining device further comprises a second providing unit for providing a second distribution of strain values or of curvature values at a plurality of points along the object, and a position determining unit for determining the position of the object relative to the path on the basis of the first and second distributions.

Methods, systems, and techniques are provided to a position determination device for determining a position of an instrument within a tubular structure. The position determination device comprises a first curvature values providing unit for providing first curvature values being indicative of first curvatures of the tubular structure at several first locations along the tubular structure and a second curvature values providing unit for providing second curvature values being indicative of second curvatures of the instrument at several second locations along the instrument. A position determination unit determines the position of the instrument within the tubular structure based on the first and second curvature values.

The invention relates to an image processing device () for finding corresponding first and second regions in two image data sets of an object. In a first image data set a source line and in a second image data set a corresponding target line are determined depending on reference regions detectable in both image data sets. A first region in the first image data set is projected onto the source line, thereby dividing the source line into two source sub-lines and defining a source ratio as the ratio of the length of one of the source sub-lines to the length of the entire source line. A second region in the second image data set is then determined such that a projection of the second region onto the target line leads to a corresponding target ratio which is similar to the source ratio.

An apparatus for adjusting images is provided. The apparatus comprises an image decomposing unit for decomposing an input image I into high-pass images HP, HP, . . . , HPN and a low-pass image LPN, and an image adjusting values determining unit for determining high-pass image adjusting values &#x3b5;, &#x3b5;, . . . , &#x3b5;for adjusting the high-pass images HP, HP, . . . , HPN and a low-pass image adjusting value &#x3b4;for adjusting the low-pass image LPN. The apparatus further comprises an image adjusting unit for adjusting the high-pass images HP, HP, . . . , HPN using the high-pass image adjusting values &#x3b5;, &#x3b5;. . . , &#x3b5;and the low-pass image LPN using the low-pass image adjusting value &#x3b4;, and an image recomposing unit for recomposing the adjusted high-pass images HP*, HP*, . . . , HPN* and the adjusted low-pass image LPN* into an adjusted image A.

The invention relates to a method for segmentation of a digital image being represented by picture element data for the purposes of visualization, segmentation and quantification, such as determining the volume of a segment. The method comprises the steps of performing a watershed transformation of the digital image by applying a watershed transformation method on the picture element data to provide one or more basins and post-processing by processing the picture element data belonging to at least one of the basins, where post-processing is one or a combination of the following steps: (i) gray-scale based segmentation, (ii) visualization using a transfer function, or (iii) volumetry using histogram analysis.
