As promised, here is a #tweetorial on spatially-fractionated radiotherapy aka Lattice aka GRID.

If you missed the #CTOS2019 talk by @Notorious_RBE, this one is for you! Spatial fractionation aims to intentionally deliver heterogeneous dose: alternating “hot” and “cold” areas with a differential of 30-100% Rx.

Thats right: you want 30% cold spots in tumor. (👇 #MedPhys reaction).
