Abstract: A common approach when reconstructing a 3D model from medical images is to do segmentation and registration manually and reconstruct these images in Maya or other 3D modeling software. To afford an effective interaction with serially sectioned medical images and reconstructed 3D models, we propose VRKidney. This medical simulation software acts as a common VR tools on computer for man-machine interaction. By integrating image registration, segmentation and reconstruction, VRKidney provides a fast registration and segmentation method using ITK and an interactive manipulation using VTK. This paper discusses the implementation of VRKidney for serially sectioned images and 3D models of human kidney and provides an initial evaluation of the usability of VRKidney in virtual human functions simulation.

The adsorptions of fixed groups −COOH, −OH, −CN, −NH 2 and −SH of dye molecules on three kinds of SnO 2 (110) surfaces were systematically investigated by first principle calculations. It is found that the adsorptions of five fixed groups on three kinds of SnO 2 (110) surfaces are chemical adsorption which includes both dissociative adsorption and non-dissociative adsorption. The most stable adsorption configuration of the five fixed groups on three kinds of SnO 2 (110) surfaces is bidentate chelate adsorption configuration of COOH group on Pt-doped SnO 2 (110) surface with adsorption energy of −3.265 eV. Thus, −COOH group is a promising fixed group of dye molecules for the preparation of dye-sensitized solar cells (DSSCS). At the same time, the Pt-doped SnO 2 photo-anode shows optimal adsorption performance, which provides theoretical basis for the design and application of SnO 2 dye-sensitized cells.
