WebApr 5, 2016 · The final state of the tumor at the end of a radiotherapy course is dependent on the doses given in each fraction during the treatment course. This study investigates … WebRadiotherapy aims to deliver ablative dose to the tumour with minimal normal tissue exposure - this requires accurate alignment of treatment beam with patient anatomy. Organ motion during treatment violates such alignment, and may compromise treatment efficacy significantly. One motion management strategy is to adaptively reposition and reshape … WebDec 5, 2005 · Abstract. Adaptive radiation is defined as the evolution of ecological and phenotypic diversity within a rapidly multiplying lineage. When it occurs, adaptive radiation typically follows the colonization of a new environment or the establishment of a “key innovation,” which opens new ecological niches and/or new paths for evolution. fl notary affidavit
