DOI: 10.1002/acm2.13646
Abstract: Abstract Purpose We investigated the hypothesis that the transmission function of rounded end linearly traveling multileaf collimators (MLCs) is constant with position. This assumption is made by some MLC models used in clinical treatment planning… read more here.

DOI: 10.1007/s00024-019-02186-4
Abstract: Seismic ray-tracing methods are widely used in seismology, with most such algorithms being executed in Cartesian or spherical coordinate systems. However, the actual Earth is not a perfect sphere but rather an ellipsoid, meaning that… read more here.
