“…One of the most promising approaches to achieve real-time frame rates for volume rendering is the use of special-purpose volume rendering hardware. New commodity hardware systems are rapidly emerging for real-time 3D visualization [14]. After a detailed analysis on the algorithms and platforms, the graphics-rendering engine was setup using 2 GB VolumePro 1000card by TeraRecon Inc. [15] and nVIDIA GeForce graphics processor running in parallel to render the 3D medical dataset (either volumetric or geometric).…”

Over the past three decades computer graphics and virtual reality (VR) have played a significant role in adding value to medicine for diagnosis and treatment applications. Medical simulation is increasingly used in medical training and surgical planning. This paper investigates the multi-modal VR interface for medical simulation focusing on motion tracking, stereographic visualization, voice navigation, and interactions. Applications in virtual anatomy learning, surgical training and pre-treatment planning will also be discussed.

“…Volumetric modelling (volume rendering) is a visualisation technique (Kaufman et al 2000(Kaufman et al , 1993aGibson 1998), where 3-D models of human organs are generated from scanned images, such as Magnetic Resonance Imaging (MRI), Computer Tomography (CT), or Positron Emission Tomography (PET) scans. These images are then displayed as high quality voxel-based 3-D volumetric models.…”

In this paper we present a number of the immersive VR applications that we have developed during the past 18 months as a means of practically demonstrating the modelling approaches previously reported. The paper discusses the usefulness of the different approaches in assisting medical practitioners to diagnose and track conditions which might lead to impairment or disability, and how they can be used to train medical students to recognise such conditions or to undertake associated medical procedures. Initial findings of a survey of undertaken with medical practitioners as to the effectiveness of VR and in particular immersive models as diagnostic and training aids are also presented.

“…Consider the scenery where smoke rises up through a cloud, or a radiation beam penetrates through a human organ. When objects occupy the same space, colors from each object must be separately classified and shaded prior to being modulated [10]. Because the Cube design features a slice-by-slice processing order, slices from different overlapping volumes have to be interlaced for a correct rendering.…”

We present a novel two-pass approach for both 2D image and 3D volume rotation. Each pass is a pseudo shear. However, it has the similar regularity to a pure shear in that a beam remains rigid. Furthermore, the 3D pseudo shear guarantees that beams within one major axis slice remain in the same directional plane after the shearing. These properties make it feasible to implement the pseudo shears on a multi-pipelined hardware or a massively parallel machine. Compared with the existing decompositions, ours offer a minimum number of shears to realize an arbitrary 3D rotation. Our decomposition also preserves the image/volume quality by guaranteeing no minification for the first pass shear.
