Embodiment Construction

[0030] figure 1 An outline of an image processing system 100 for contouring three-dimensional medical image data according to one embodiment of the present invention is shown. The system 100 includes a processing unit 140 plus a first interface 110 , a second interface 120 and a third interface 130 respectively. Preferably, a memory 150 is also included, which stores software for performing the processes described below when the software is run on the processing unit 140 . For presentation purposes, figure 1 Interfaces 110, 120 and 130 are illustrated as separate entities. However, in a practical implementation two or more of these interfaces may be integrated into a common unit.

[0031] The first interface 110 is configured to enable the processing unit 140 to access the source data SD in the form of three-dimensional medical image data representing the anatomical structure of interest. The source data SD also contains tissue adjoining the anatomical structure of interes...

Abstract

An anatomic structure of interest is contoured in 3D source data by selecting a first subset of data in a first image slice at a first axial position (z1). A first set of instructions identifies a first edge (E1) of the anatomic structure of interest in the first image slice. Then, a second subset of data is selected in a second image slice at a second axial position (z2); and a second set of inst- ructions identifies a second edge (E2) of the anatomic structure of interest in the second image slice. A three-dimensional shell (3DS) is calculated based on the first and second edges (E1; E2) andthe source data (SD). The three-dimensional shell (3DS) represents an approximation of a delimiting surface that separates the anatomic structure of interest from adjoining tissues in the 3D source data.

Description

technical field [0001] The present invention generally relates to solutions for enhancing the information content of medical image data. More specifically, the invention relates to an image processing system and a corresponding method according to the preamble of claim 1 . The invention also relates to computer programs and processor-readable media. Background technique [0002] The process of defining voxels representing specific anatomical structures, or so-called organ delineation, is one of the most tedious and time-consuming parts of radiotherapy planning. This process typically involves manually animating outlines in 2D slices using simple drawing tools, and can take hours to delineate all structures of interest in the high-resolution 3D dataset used for planning.
