In the use of MRI in acute stroke patients, determination of the perfusion-diffusion (PWI-DWI) mismatch is highly important, since it indicates possible enlargement of the ischemic lesion or deterioration of the patient. When quantitative measures are used such as the ADC of CBF to predict ischemic damage, accurate registration of the ischemic lesion on follow-up MRI to the results obtained in the first MRI is essential. Problems in the registration of stroke images include differences in patient orientation and/or low cooperativeness of the patient in the hyperacute stage of stroke. The aim of the present study is to develop a robust method of stroke image registration.
Mass-casualty triage simulation requires the realistic depiction of wounds and other signs of external injury on victims. Texture maps permit images of actual wounds to be rendered over computer models. Several images...

We present a physically-based, elastically deformable particle system model that combines the oriented particles used in surfaceonly models, and the unoriented particles used in volume-only simulations into a bag of p...

Accurate brain tissue segmentation by intensity-based voxel classification of MR images is complicated by partial volume (PV) voxels that contain a mixture of two or more tissue types. In this paper 1, we present a st...
