We tried to improve the basic three-dimensional reconstruction technique by comparing preprocessing, segmentation, shading and rendering techniques in 15 examples of MR investigations of the knee joint. We conclude that signal-normalising, combined threshold and tracking segmentation, grey-level-gradient shading, and combined surface and volume rendering (i. e. hybrid rendering) are the methods of choice for the three-dimensional reconstruction process.
