"This article deals with three-dimensional reconstruction methods of nuclear magnetic resonance images. The testing images were observed by tomograph with basic magnetic field of 4.7 T at the Institute of Scientific Instruments (Academy of Sciences of the Czech Republic). There were acquired 10 slices of the testing phantom. There were found methods with the aim of getting utmost information about the shape of the testing phantom. One possible way is to increase the count of the sensed slices, but it implies decreasing of the signal to noise ratio. The second approach is finding the compromise between the effective count of slices and the following interpolation of other slices between the sensed ones. The both approaches were compared. The resultant images were segmented by the active contour methods which are based on partial differential equations solution [1], [2]. The advantage of these methods is that the images may not be preprocessed before segmentation. The appropriate segmented slices were co"@en .
