This paper describes work in progress to explore the transfer of focus+context ideas from Information Visualization to Volume Visualization. Section 2 gives background to the two fields which we bring together in this research. In section 3 we present a taxonomy of focus and context methods for volume visualization, in terms of nature of focus region, type of focus effect and space in which the effect is applied. Section 4 details two particular methods that we have implemented, and describes their application to a medical dataset - this dataset is of a cerebral aneurysm in the Circle of Willis, requiring focus on an aneurysm without losing context of the surrounding arteries.
