Automated Detection of Regions of Interest for Brain Perfusion MR Images [PDF]

open access: yes, 2018
Images with abnormal brain anatomy produce problems for automatic segmentation techniques, and as a result poor ROI detection affects both quantitative measurements and visual assessment of perfusion data.

A New Concept for Kilotonne Scale Liquid Argon Time Projection Chambers

open access: yesInstruments, 2020
We develop a novel Time Projection Chamber (TPC) concept suitable for deployment in kilotonne-scale detectors, with a charge-readout system free from reconstruction ambiguities, and a robust TPC design that reduces high-voltage risks while increasing the
