Abstract
A method to generate an attenuation correction map to compensate imaging errors in emission tomography resulting from the presence of hardware parts inside the imaging volume of an emission tomograph. Components of 3-dimensional CAD models of the hardware parts to be compensated are converted into voxels on a predetermined grid and assigned a filling factor per voxel. Image data sets of each component are multiplied with respective attenuation coefficients and thereafter superimposed to form an attenuation correction map. Thereby, in a simple and automatable way a profoundly exact, mostly noise-free and exactly reproducible attenuation correction map for attenuation correction in an emission tomography device may be generated.
