Adapta studio: a case study in the medical sector

These object have been obtained by 3D4MED by using 3d medical imaging techniques and are used for 3d printing applications. However , due to the reconstruction techniques and the 3D scanning techniques in general, they are very hard to process. In fact they are composed by millions upon millions polygons and this can be a problem when they are opened and analysed con computer screens.

The usage of the AMAZ3D software permits to highly reduce polygon count without affecting quality.

Case study #1

Abdominal organs (Kidneys, Pancreas, Duodenum and Spleen) with arterial and venous vascularizations for anatomical comprehension in living donor Kidney procurement. Having a single small and manageable file with different structures of different colors allows the user to better evaluate the anatomy and to select the most suitable approach for the donor Kidney procurement. The use can be easily extended to the pre-operative planning of different complex surgical procedures involving many anatomical structures.

Case study #2

Paediatric rib cage for surgical planning of bone tumor removal. 3d models of very large bone structures (i.e. rib cage) are difficult to manage since the number of triangles is very high. Having small and manageable files allows to share the model with the surgeon for visualization and anatomical comprehension. Moreover, it allows to carry out post-processing operations on the to create a model useful for the pre-operative planning of the surgical intervention.

Conclusions

The collaboration with Adapta Studio’s team was great! Amaz3D software is used regularly at 3D4Med Lab for the triangles’ reduction of STL files which alternatively would not be manageable for 3d printing. We advise those who are dealing with 3D models resulting from segmentation on medical images to use Amaz3D software to streamline the post-processing procedure of the virtual mode.
