We present a hybrid multi-volume rendering approach based on a novel Residency Octree that combines the advantages of out-of-core volume rendering using page tables with those of standard octrees. Octree approaches work by performing hierarchical tree traversal....We enable flexible mixed-resolution out-of-core multi-volume rendering by decoupling the cache residency of multi-resolution data from a resolution-independent spatial subdivision determined by the tree.

In this paper, we share the process we went through to reach our simple, but effective, solution for integrating multi-volume rendering into an exploratory visualization environment for the diagnosis of FCD. We focus on fetching of multiple data assigned to a sample when they are rendered.

Results: The multi-volume rendering system achieved an interactive frame rate (> 15 fps) when rendering five small volumes (128 (3) voxels), four medium-sized volumes (256(3) voxels), and two large volumes (512(3) voxels).

Using this metaphor, we propose several ways to compute the safety of paths from the region of interest to all tumor voxels and show how this information can be visualized in real-time using a multi-volume rendering system.

In this paper, we present a new multi-volume rendering technique (i.e., progressive fusion) to combine 3D anatomical structures from B-mode imaging and flow information from power Doppler imaging....We have evaluated the progressive-fusion multi-volume rendering method with the phantom and in vivo data acquired using a commercial ultrasound machine (EUB-8500, Hitachi Medical Corporation, Japan) with a 3.5 MHz mechanical probe.
Real-time volume rendering visualization of dual-modality PET/CT images with interactive fuzzy thresholding segmentation [0.03%]

This technique is then incorporated into a real-time multi-volume rendering of PET/CT images. Our method allows a real-time fusion and interchangeability of segmentation volume with PET or CT volumes, as well as the usual fusion of PET/CT volumes.
A direct multi-volume rendering method aiming at comparisons of 3-D images and models [0.03%]
