BUbble Flow Field: a Simulation Framework for Evaluating Ultrasound Localization Microscopy Algorithms

no code implementations1 Nov 2022 Marcelo Lerendegui, Kai Riemer, Bingxue Wang, Christopher Dunsby, Meng-Xing Tang

The ability to produce ULM images, and the availability of a ground truth in localisation and tracking enables objective and quantitative evaluation of the large number of localisation and tracking algorithms developed in the field.

Fast and selective super-resolution ultrasound in vivo with sono-switchable nanodroplets

no code implementations8 Mar 2022 Kai Riemer, Matthieu Toulemonde, Jipeng Yan, Marcelo Lerendegui, Eleanor Stride, Peter D. Weinberg, Christopher Dunsby, Meng-Xing Tang

Ultrasound Localization Microscopy (ULM) provides very high spatiotemporal resolution but the use of microbubbles requires low contrast agent concentrations, a long acquisition time, and gives little control over the spatial and temporal distribution of the bubbles.
