| Title | An optimising feature in StarTrack software for analysing diffusion MRI data |
| Description | StarTrack is a program developed in Matlab to analyse diffusion imaging data using DTI, spherical deconvolution (SD) and tractography. At its core, it computes diffusion tensors or fibre orientation distributions (FOD) and performs whole-brain tractography using different algorithms to map the human white matter anatomy. A part of my project was to implement a gradient optimisation method in finding the local maxima of these 3D spherical functions (FODs) within the StarTrack software and assist the implementation of 2 different bootstrapping methods for uncertainty calculations in the analysis. |
| Type Of Technology | Software |
| Year Produced | 2018 |
| Open Source License? | Yes |
| Impact | The optimisation algorithm added to the software allows for for a more precise estimation of the directionality of fibre organization on a sub-voxel level in diffusion MRI data and therefore outputting more precise structural connectivity measures. |

| Description | Conference presentations (ISMRM 2017, ISMRM 2018, OHBM 2018) |
| Form Of Engagement Activity | A talk or presentation |
| Part Of Official Scheme? | No |
| Geographic Reach | International |
| Primary Audience | Other audiences |
| Results and Impact | A talk presentation and poster presentations have been done at 2 different international conferences - International Society for Magnetic Resonance in Medicine (ISMRM) in 2017 and 2018, and Organisation for Human Brain Mapping (OHBM) in 2018. The attendance at the talk was 50-100 people. The questions after the presentations started debated and triggered ideas for future research. Multiple people approached me after the talk to get more information on the results of my research. |
