Designing Casual Serious Games in Science. The case of "Couch Potatoes Defense"

Quantification and modelling of the dosimetric impact of the treatment couch in volumetric modulated arc therapy (VMAT)

Background: As the volumetric modulated arc therapy (VMAT) becoming a main role of treatment ways, the effect of couch top becomes more significant. It is imperative to re-evaluate the couches that previously may have been considered of no importance during early treatment techniques. The impact of couch top on radiation delivery was explored and the couch model was tested with the aim of reduc...
