Using global illumination in volume visualization of rheumatoid arthritis CT data.

Published in IEEE Computer Graphics and Applications

Proper lighting in rendering is essential for visualizing 3D objects, but most visualization software tools still employ simple lighting models. The advent of hardware-accelerated advanced lighting suggests that volume visualization can be truly usable for clinical work. Researchers studied how volume rendering incorporating global illumination imp...

Excitation spectroscopy in multispectral optical fluorescence tomography: methodology, feasibility and computer simulati...

Published in Physics in Medicine and Biology

Molecular probes used for in vivo optical fluorescence tomography (OFT) studies in small animals are typically chosen such that their emission spectra lie in the 680-850 nm wavelength range. This is because tissue attenuation in this spectral band is relatively low, allowing optical photons even from deep sites in tissue to reach the animal surface...
