Calculation of renal volume in pregnant bitches: a) calculation by two-dimensional method (ellipsoid): in plane A is measured length and in plan B the width and depth, which is automatically calculated the volume by the software, b) calculation by three-dimensional method (VOCAL): in plane A the kidney was rotated in “z” axis, and its external surface defined in manual mode, with rotation by 30° (6 plans) or 12 (15 plans). At the end of the delimitation of the latter area the program automatically calculated the volume and provided a three-dimensionally reconstructed image. VOCAL: Virtual Organ Computer-aided AnaLysis
