文摘
- •
Federated optimisation is a new method for kinetic analysis of dynamic medical images.
- •
It exploits inherent redundancy in images to efficiently improve time activity curve fits.
- •
Visual consistency is sometimes slightly improved, without explicit regularisation.
- •
The method is agnostic to model formulation.
