Regensburg Breast Shape Model (RBSM)

princ_modes_8_noLabels

The Regensburg Breast Shape Model (RBSM) is a 3D statistical shape model of the female breast, learned from 110 breast scans. It is the first ever which is publicly available and free for research purposes. This work was done in Cooperation between the  Regensburg Medical Image Computing (ReMIC) lab at OTH Regensburg and the University Center of Plastic-, Aesthetic-, Hand- and Reconstructive Surgery at the University Hospital Regensburg.

Visualize the RBSM


The RBSM can be easily visualized with the Scalismo Viewer, developed by the Graphics and Vision Research Group of the University of Basel. We provide a pre-compiled, executable jar file here:

Note that Java need to be installed on your computer (Java version 8.0 or higher is recommended).

Loading the RBSM into the Scalismo Viewer: Open the Scalismo Viewer -> Right click on Default Group -> Select Load Statistical Shape Model -> Browse for the downloaded RBSM and click Open.
