SPL Inner Ear Atlas

Launch SPL Inner Ear Atlas

The SPL Inner Ear Atlas is an human ear based on CT stans from a experimental CT scanner. It was created as a joint project between the German Cancer Research Center and the SPL.


The atlas was derived from a high-resolution flat-panel computed tomography (CT) scan (aprox 140 µm high contrast resultion), using semi-automated image segmentation and three-dimensional reconstruction techniques [Gupta, Bartling, et al. AJNR Am J Neuroradiol. 2004]. The current version consists of the original CT scan; a set of detailed label maps; a set of three-dimensional models of the labeled anatomical structures.

The SPL Ear Atlas provides important reference information for surgical planning, anatomy teaching, and template driven segmentation.
