The advents of technologies have led to tremendous increases in the diversity and size of the available data. In the field of medicine, the advancements in medical imaging technologies have dramatically improved the quality of the acquired data, such as a higher resolution and higher signal-to-noise ratio. In addition, the dramatic reduction of the acquisition time has enabled the studies of organs under function.At the same pace, the progresses in the field of biology and bioinformatics have led to stable automatic algorithms for the generation of biological data. As the amount of the available data and the complexity increase, there have been great demands on efficient analysis and visualization techniques to support quantitative visual analysis of the huge amount of data that we are facing. This thesis aims at supporting quantitative visual analysis in the presence of data uncertainty within the context of medicine and biology. In this thesis, we present several novel analysis techniques and visual representations to achieve these goals. The results presented in this thesis cover a wide range of applications, which reflects the interdisciplinary nature of scientific visualization, as visualization is not for the sake of visualization. The advances in visualization enable the advances in other fields. In typical clinical applications or research scenarios, it is common to have data from different modalities. By combining the information from these data sources, we can achieve better quantitative analysis as well as visualization. Nevertheless, there are many challenges involved along the process such as the co-registration, differences in resolution, and signal-to-noise ratio. We propose a novel approach that uses light as an information transporter to address the challenges involved when dealing with multimodal data. When dealing with dynamic data, it is essential to identify features of interest across the time steps to support quantitative analyses. However, this is a time-consuming process and is prone to inconsistencies and errors. To address this issue, we propose a novel technique that enables an automatic tracking of identified features of interest across time steps in dynamic datasets. Although technological advances improve the accuracy of the acquired data, there are other sources of uncertainty that need to be taken into account. In this thesis, we propose a novel approach to fuse the derived uncertainty from different sophisticated algorithms in order to achieve a new set of outputs with a lower level of uncertainty. In addition, we also propose a novel visual representation that not only supports comparative visualization, but also conveys the uncertainty in the parameters of a complex system. Over past years, we have witnessed the rapid growth of available data in the field of biology. The sequence alignments of the top 20 protein domains and families have a large number of sequences, ranging from more than 70,000 to approximately 400,000 sequences. Consequently, it is difficult to convey features using the traditional representation. In this thesis, we propose a novel representation that facilitates the identification of gross trend patterns and variations in large-scale sequence alignment data.The ISBN 978-91-7519-514-8 on the title page is incorrect.
