1. Hypoxic Target Volume Determination in PET/CT Imaging : The Impact of Deformable Image Registration
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Using a tailored dose distribution for personalized radiotherapy with the help of positron emission tomography (PET) might give an edge for successful tumour elimination. One of the main determinants for tumour radioresistance in several solid tumours has been investigated as hypoxia, including head and neck cancer (HNC). READ MORE
