Visual Analysis of Lung Cancer Imaging Data Using Multidimensional Projections Techniques

Lung tumors are heterogeneous entities consisting of distinct intra-tumor regions with different biological characteristics. Currently, the only means to explore and analyze these distinct intra-tumor regions is to inspect several image acquisitions. From these, per-voxel functional tissue parameters, representative of tissue properties, are...

RegistrationShop: An interactive 3D medical volume registration tool

Image registration is a technique where two images or volumes are mapped onto each other. In medical imaging this is used to combine and compare images from patients in order to find abnormalities or to track a patient’s treatment effects over time. There are registration algorithms and software packages available, but they are cumbersome and...

Direct Visualization of Photographic Volumes

Volume visualization of photographic data is a relatively new domain for medical visualisation. In photographic volumes, voxel colour is predetermined, making colour selection through transfer functions less important, or even unnecessary. However, voxel classi?cation from photographic data is more complex than classi?cation from scalar datasets...

Enhanced visualization for improved lesion diagnosis in virtual colonoscopy

The risk of developing colon cancer is strongly correlated with the appearance of polypoid lesions (also called polyps) in the large intestine [Santoro et al. 2008]. Not all polyps are dangerous; in fact only one percent of polyps smaller than one centimeter is dangerous. However, when polyps grow bigger the risk quickly increases to over fifty...
