Renal size provides information for the diagnosis and prognosis of kidney diseases. Volume measurement is usually based on semi-axis derived from Ultrasound (US) imaging. Complex pathologies such as Polycystic Kidney Disease (PKD) require complex imaging studies that include contrast media and ionising radiations (X Rays), which are not suitable due toxicity and accumulation of radiation effects. We have developed NEFROVOL which is a low cost, non-invasivesolution to reconstruct the renal structure and to estimate ist volume. To do so, NEFROVOL processes parallel ultrasound images to generate a 3D kidney model. We suggest a way to record the set of images in a DICOM compatible way, since DICOM does not support multiple US slices, similar to CT scans. Tests on geometric solids, fruits and patients yield estimates within 10,% 17% and 25% of the real volume, respectively. NEFROVOL generates electronic medical record documents in CDA standard, as a single measure or as a trend over the years. NEFROVOL is compatible with 3D printing by generating files in STL format.
