TY - THES A1 - Neumann, Mario T1 - Localization and Classification of Teeth in Cone Beam Computed Tomography using 2D CNNs N2 - In dentistry, software-based medical image analysis and visualization provide effcient and accurate diagnostic and therapy planning capabilities. We present an approach for the automatic recognition of tooth types and positions in digital volume tomography (DVT). By using deep learning techniques in combination with dimension reduction through non-planar reformatting of the jaw anatomy, DVT data can be effciently processed and teeth reliably recognized and classified, even in the presence of imaging artefacts, missing or dislocated teeth. We evaluated our approach, which is based on 2D Convolutional Neural Networks (CNNs), on 118 manually annotated cases of clinical DVT datasets. Our proposed method correctly classifies teeth with an accuracy of 94% within a limit of 2mm distancr to ground truth landmarks.

In orthopaedics and biomechanics, SSMs are increasingly employed to individualize measurement data or to create individualized anatomical models. The human spine is a versatile and complex articulated structure and thus is an interesting candidate to be modeled using an advanced type of SSMs. For modeling and analysis of articulated structures, so called articulated SSMs (aSSMs) have been developed. However, a missing feature of aSSMs is the consideration of collisions in the course of individual fitting and articulation. The aim of this thesis is to develop an aSSM of two adjacent vertebrae that handles collisions between components correctly. The model will incorporate the two major aspects of variability: Shape of a single vertebra and the relative positioning of neighboring vertebrae. That way it becomes possible to adjust shape and articulation in view of a physically and geometrically plausible individualization. To be able to apply collision-aware aSSMs in simulation and optimisation in future work, the approach is based on a parallelized collision detection method employing Graphics Processing Units (GPUs).

Due to the explicit character of Lie group operations, our non-Euclidean method is very efficient allowing for fast and numerically robust processing.

However, relying on fully supervised deep learning for this task is challenging because manual annotation occupies valuable time of the clinical experts. Methods We introduce a teacher–student learning approach that learns jointly from annotated simulation data and unlabeled real data to tackle the challenges in simulation-to-real unsupervised domain adaptation for endoscopic image segmentation. Results Empirical results on three datasets highlight the effectiveness of the proposed framework over current approaches for the endoscopic instrument segmentation task. Additionally, we provide analysis of major factors affecting the performance on all datasets to highlight the strengths and failure modes of our approach. Conclusions We show that our proposed approach can successfully exploit the unlabeled real endoscopic video frames and improve generalization performance over pure simulation-based training and the previous state-of-the-art. This takes us one step closer to effective segmentation of surgical instrument in the annotation scarce setting.
