3D Model-Based Parameter Quantification on Resource Constrained Hardware using Double-Buffering

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Reconstructing 3D parameter maps of huge volumes entirely on the GPU is highly desirable due to the offeredcomputation speed-up. However, GPU memory restrictions limit the coverable volume. To overcome thislimitation, a double-buffering strategy in combination with model-based parameter quantification and 3D-TGVregularization is proposed. This combination warrants whole volume reconstruction while maintaining thespeed advantages of GPU-based computation. In contrast to sequential transfers, double-buffering splits thevolume into blocks and overlaps memory transfer and kernel execution concurrently, hiding memory latency.The proposed method is able to reconstruct arbitrary large volumes within 5.3 min/slice, even on a single GPU.
