Original Abstract

To imaging soft tissues is usually used tomography by magnetic resonance. Ideally, several tissue slices in three orthogonal planes (sagittal, coronal, transverse) are acquired. With slices in three planes is following reconstruction of shape of examined tissues most accurate. In case of acquired slices only in one plane the high spatial information lost occurs by image acquisition. Then it is necessary the shape of tissue appropriately reconstruct. At first the images are segmented and with use of particular segments the three dimensional model is composed. The reconstructed model has step-surface. There are several methods for smoothing the shape. In this article are discussed the methodology for shape smoothing. The results of volumetry with use of several smoothing levels are compared. Impact of shape smoothing to quality of reconstruction is discussed.
