Simulation of Interventional Neuroradiology Procedures
Found in: Medical Imaging and Augmented Reality, International Workshop on
By Wieslaw L. Nowinski, Chee-Kong Chui
Issue Date:June 2001
pp. 0087
Abstract: We describe the design and development of a computer environment for planning interventional neuroradiology procedures. The Neuroradiology Catheterization Simulator called NeuroCath is intended for interventional procedures involving vascular mal...
 
A VR Simulator for Intracardiac Intervention
Found in: IEEE Computer Graphics and Applications
By P. Chiang, Jianmin Zheng, You Yu, Koon Hou Mak, Chee Kong Chui, Yiyu Cai
Issue Date:January 2013
pp. 44-57
A VR simulator provides low-cost, realistic training for intracardiac techniques for determining the heart's mechanical and electrical activities. A geometric method models interaction between a catheter and the heart wall. Boundary-enhanced voxelization a...
 
In situ spatial AR surgical planning using projector-Kinect system
Found in: Proceedings of the Fourth Symposium on Information and Communication Technology (SoICT '13)
By Chee-Kong Chui, Chin-Boon Chng, Binh P. Nguyen, Rong Wen
Issue Date:December 2013
pp. 164-171
Traditional surgical planning is challenged by limited spatial information of 2-D medical images or separated planning phases between 3-D model based virtual planning and its in situ registration. This paper presents an augmented surgical planning method w...
     
Ant colony optimization for model predictive control for blood glucose regulation
Found in: Proceedings of the Third Symposium on Information and Communication Technology (SoICT '12)
By Binh P. Nguyen, Chee-Kong Chui, Yvonne Ho
Issue Date:August 2012
pp. 214-217
This paper presents an adaptation of the Ant System method to find the optimal control input for blood glucose regulation using Model Predictive Control (MPC). The Ant System optimization method was implemented to solve a linear MPC problem and performance...
     
Implementation of model predictive control with modified minimal model on low-power RISC microcontrollers
Found in: Proceedings of the Third Symposium on Information and Communication Technology (SoICT '12)
By Binh P. Nguyen, Chee-Kong Chui, Yvonne Ho, Zimei Wu
Issue Date:August 2012
pp. 165-171
Due to the ability of modeling multivariable systems and handling constraints in the control framework, model predictive control (MPC) has received a lot of interest from both academic and industrial communities. Although it is an established control techn...
     
Particle-based simulation of blood flow and vessel wall interactions in virtual surgery
Found in: Proceedings of the 2010 Symposium on Information and Communication Technology (SoICT '10)
By Binh P. Nguyen, Chee-Kong Chui, Dong Ni, Jing Qin, Wai-Man Pang
Issue Date:August 2010
pp. 128-133
We propose a particle-based solution to simulate the interactions between blood flow and vessel wall for virtual surgery. By coupling two particle-based techniques, the smoothed particle hydrodynamics (SPH) and mass-spring model (MSM), we can simulate the ...
     
Prediction-based directional search for fast block-matching motion estimation
Found in: Proceedings of the 2010 Symposium on Information and Communication Technology (SoICT '10)
By Binh P. Nguyen, Chee-Kong Chui, Sim-Heng Ong, Trang T. T. Do
Issue Date:August 2010
pp. 86-91
This paper proposes an efficient block-matching motion estimation algorithm known as prediction-based directional search (PDS). This new algorithm is applicable to a wide range of video processing applications. The algorithm uses the motion vectors in two ...
     
The LogP and MLogP models for parallel image processing with multi-core microprocessor
Found in: Proceedings of the 2010 Symposium on Information and Communication Technology (SoICT '10)
By Chee-Kong Chui
Issue Date:August 2010
pp. 23-27
Despite the advancement and availability of the multiple core microprocessors, it remains an issue on how to fully utilize this relatively new computing platform to achieve optimal performance for a parallel algorithm. There are limitations to the existing...
