interactive volume rendering for virtual colonoscopy
IEEE Visualization, 1997Co-Authors: Lichan Hong, Kittiboon Junyaprasert, Shigeru Muraki, Arie E Kaufman, Yong Zhou, Zhengrong LiangAbstract:3D virtual colonoscopy has recently been proposed as a non-invasive alternative procedure for the visualization of the human colon. Surface rendering is sufficient for implementing such a procedure to obtain an overview of the interior Surface of the colon at interactive rendering speeds. Unfortunately, physicians can not use it to explore tissues beneath the Surface to differentiate between benign and malignant structures. In this paper, we present a direct volume rendering approach based on perspective ray casting, as a supplement to the Surface Navigation. To accelerate the rendering speed, Surface-assistant techniques are used to adapt the resampling rates by skipping the empty space inside the colon. In addition, a parallel version of the algorithm has been implemented on a shared-memory multiprocessing architecture. Experiments have been conducted on both simulation and patient data sets.

Conceptual Design of a Water-air Amphibious Unmanned Vehicle
DEStech Transactions on Computer Science and Engineering, 2019Co-Authors: Zhi-jun Wang, Ji-xuan Li, Yong MaAbstract:Aiming at the inefficiency of the current maritime search and rescue system, this paper aims to provide a conceptual design scheme for an amphibious unmanned Surface vehicle that can realize the integration of air and water. In this design, detailed mechanical and structural analysis were performed for each part. The amphibious unmanned vehicles can independently choose the air flight and Surface Navigation conditions in harsh sea conditions, to cruise and rescue work. At the same time, the amphibious unmanned vehicle can realize the rapidly transfer between water and air modes through the water-air dual-purpose propulsion module, thus improving the efficiency of cruise and rescue.
