Abstract Background Most studies on synthetic computed tomography (sCT) generation for brain rely on in-house developed methods. They often focus on performance rather than clinical feasibility. Therefore, the aim of this work was to validate sCT ima

ObjectivesMRI-only radiotherapy (RT) provides a workflow to decrease the geometric uncertainty introduced by the image registration process between MRI and CT data and to streamline the RT planning. Despite the recent availability of validated synthe

Kurderna i Rojava, norra Syrien, blev från 2015 västvärldens viktigaste allierade i kampen mot Islamiska staten, IS. Det började när IS attackerade staden Kobane, vars YPG-gerilla och kända kvinnliga soldater mot alla odds lyckades besegra angr

In order to give the correct dose to a patient, the monitor chamber for a proton scanning system has to be calibrated. As recombination of ion pairs occurs in the monitor chamber, the relation between the number of particles traversing it per time un
