Izdelava 3D geometrijskih modelov jeter

Žnidaršič, Urban (author), Kunc, Robert (mentor)

Jetra so organ v človeškem telesu, ki se zelo dobro obnavlja. Da bi lahko predvideli, kako hitro bi se jetra obnavljala po operaciji, bi potrebovali geometrijske modele jeter, na katerih bi lahko izvajali simulacije. Te modele smo poskusili izdelati s 3D skeniranjem korozijskih odlitkov jeter ter s segmentacijo posnetkov, narejenih z magnetno resonanco in računalniško tomografijo. S 3D skeniranjem modelov ni bilo mogoče izdelati, s segmentacijo pa smo dobili modele različnih kvalitet. Na kvaliteto končnih modelov sta najbolj vplivali ločljivost in barvna homogenost uporabljenih posnetkov.

• Title: Creation of 3D geometric models of liver

Abstract

The liver is an organ in the human body with exceptional regeneration properties. In order to predict the regeneration rate after surgery we would need geometric models of liver on which we could perform simulations. We tried to create these models by 3D scanning vascular corrosion casts of liver and by segmentation of magnetic resonance and computed tomography images. Creation of models by 3D scanning was not possible and the models acquired by segmentation varied in quality. The factors that affected quality of the final models the most were image resolution and colour homogeneity.
