Simulations of Complex and Microscopic Models of Cardiac Electrophysiology Powered by Multi-GPU Platforms
Key aspects of cardiac electrophysiology, such as slow conduction, conduction block, and saltatory effects have been the research topic of many studies since they are strongly related to cardiac arrhythmia, reentry, fibrillation, or defibrillation. However, to reproduce these phenomena the numerical models need to use subcellular discretization for the solution of the PDEs and nonuniform,…
Realistic Simulation of Tomato Garden Based on GPU
The objective of this study is to present a fast algorithm to simulate a virtual tomato garden based on GPUs acceleration. Parametric L-system is used to describe the topological structure of individual tomato plants.
Real-time Mandibular Angle Reduction Surgical Simulation with Haptic Rendering
The real-time methods for bone removal and reconstruction during surgical procedures have been proposed to support realistic visual feedbacks. The simulated contact forces were verified by comparing against the actual force data measured through the constructed mechanical platform.
Temporal and spectral imaging with micro-Computer Tomography
Our proposed method produces five-dimensional volumetric images that distinguish different materials at different points in time, and can be used to segment regions containing iodinated blood and compute measures of cardiac function.
Parallel perfusion imaging processing using GPGPU
In this paper, we will present the implementation of a deconvolution algorithm for brain perfusion quantification on GPGPU (General Purpose Graphics Processor Units) using the CUDA programming model. We present the serial and parallel implementations of such algorithms and the evaluation of the performance gains using GPUs.
