1. A system that retrieves a volumetric image data subset comprised in data storage of volumetric image data sets, the system comprising: a first query hardware unit that composes a first query that searches the data storage for a volumetric image data set comprising the volumetric image data subset; a second query hardware unit that composes a second query that searches the volumetric image data set for the volumetric image data subset, the second query comprising anatomical structure information that identifies an anatomical structure within the volumetric image data set; a first determination hardware unit that determines the volumetric image data set based on the first query; a second determination hardware unit that determines the volumetric image data subset of the volumetric image data set based on the anatomical structure identified within the volumetric image data set using the anatomical structure information comprised in the second query; a segmentation hardware unit that adapts a mesh of a shape model to identify the anatomical structure within the volumetric image data set and segments the identified anatomical structure from the volumetric data set; and a retrieval hardware unit that retrieves the segmented anatomical structure.
