“…The complex anatomical structure of the paranasal sinuses makes the development of standardized methods of segmentation and three-dimensional reconstruction limited. Previous studies 3,[9][10][11][12][13][14] have therefore needed to apply both automatic and manual methods to create 3D models. However, manual methods pose two distinct issues relating to time and expertise.…”

Human identifications are made difficult when the remains are severely fragmented or burned. In cases such as these, alternative methods of identification become vital. Three-dimensional reconstructions have increased the potential for utilizing qualitative and quantitative analysis of anatomical structures within forensic anthropology approaches. This paper presents a method to produce three-dimensional reconstructions of paranasal sinuses for biological analysis of skeletal remains. Previous published research has quantified the variability of the paranasal sinuses and has begun to explore their ability to provide biological information within forensic science contexts. However, the complex anatomical structure of the sinuses has led to significant limitations in the ability to produce three-dimensional reconstructions for analysis using an automatic approach. Therefore, this new method for developing three-dimensional models of the paranasal sinuses using an automatic approach that is suitable for a large sample size is timely. It offers a new pathway to more sophisticated methods of analysis that ultimately offer the potential to provide valid and robust distinctions between individuals and identifications in crime reconstructions.

“…The geometric representation of the paranasal sinuses plays a secondary role in the pre-and intra-operative setting as exact segmentation of the paranasal sinuses in computed tomography images is an extremely time consuming task [15,17], and flexibility and quality of the direct representation is higher. A comparison of direct and indirect rendering techniques of paranasal sinuses has been given by Rogalla [13].…”

Virtual endoscopy is among the most active topics in virtual medicine and medical imaging. It focuses on the virtual representation of minimally invasive procedures for training, planning and diagnosis without an actual invasive intervention. In the past few years, virtual endoscopy modes have been transferred from research systems in virtually every commercial medical imaging software, but with varying quality and flexibility. This report covers concepts used in current systems in research and products, and how they might be applied to daily practice in health care. Specifically, I will start with an introduction into virtual endoscopy and the related medical field. This will also include typical scenarios of virtual endoscopy applications as they appear in clinical practice. This part will be followed by a discussion of the technical issues of virtual endoscopy and how they are addressed in currently available systems. Among these issues are navigation through the respective body organ and the orientation aids for the users. In addition, I will highlight the different rendering techniques used and its impact on rendering speed and quality.
