This project aims to develop optimal, efficient and robust signal processing methods for diffusion magnetic resonance imaging (dMRI) with reduced scan times. A child, possibly distressed, can only be motionless long enough to undergo a basic dMRI scan of the brain, but enhanced forms of dMRI need at least 60 minutes. The project’s processing methods will use spherical geometries, which encode information about white matter fibres in the brain, to collect and reconstruct images. The project is expected to reduce dMRI scan times and ultimately make non-invasive and inexpensive early detection of neurological disorders such as dementia feasible.

该项目旨在开发最佳，高效和鲁棒的信号处理方法，用于减少扫描时间的扩散磁共振成像（dMRI）。一个孩子，可能是痛苦的，只能不动足够长的时间来接受基本的dMRI扫描的大脑，但增强形式的dMRI需要至少60分钟。该项目的处理方法将使用球形几何形状，它编码有关大脑中白色物质纤维的信息，以收集和重建图像。该项目预计将减少dMRI扫描时间，并最终使痴呆等神经系统疾病的非侵入性和廉价的早期检测成为可能。
