Abstract The liver tumors represent a major pathology in the medical practice, considering their high incidence, the diagnostic difficulties and the high rate of morbidity and mortality (Hosch et al., 2006). Ultrasonography remains the main imaging method for diagnosing liver tumor masses. This position is sustained by the large addressability of the investigation,its non invasive and, consecutively, repetitive character and the lower price (Badea et al., 2007). Three-dimensional ultrasound has become an increasingly important component of clinical imaging; it exploits the real-time capability of ultrasound to build a volume that can then be explored using increasingly affordable high performance workstations (Nelson, 2006). Three dimensional ultrasonography provides several advantages, increases the efficiency of the liver tumor screening by using the multi-slice function, allows a better time and human resource management, the precise location on three axes of the tumor and the exact assessment of the distances relative to the main vessel structures of the liver. It is also able to characterize the tumor texture and to sum up the total volume of liver masses, with applications in post-chemotherapy follow-up (Badea et al., 2007). |
