Publication number: 20130114785Abstract: A method is disclosed for the medical imaging of a body part, in particular the hand, wherein, in a tomographic image data record of the body part, points are marked which fix a face of interest running through the body part and which is singly or multiply curved. This curved face, which runs through all marked points, is then determined and the image content of the curved face is determined from the voxels of the image data record. This image content is mapped onto an observation plane which is finally displayed with the mapped image content on a screen. The method enables by way of example image representation of the structures of the left hand relevant to a skeleton examination by way of tomographic imaging.Type: ApplicationFiled: November 6, 2012Publication date: May 9, 2013Inventors: Gerhard ALZEN, Gabriel HARAS, Grzegorz SOZA, Andreas WIMMER
