   Abstract : Radiation and medical drugs are used to fight head and neck cancer, but unfortunately in some cases these treatments cause development of other diseases and injuries. Osteoradionecrosis (ORN) and medical-related osteonecrosis of the jaw (MRONJ) are dreaded late complications in jaws from radiation therapy and medical drugs and cause great suffering to those affected.

4. 3. osimetric impact of system spe cific geometric distortion on head and neck treatment plans in MRI only based radiation therapy

   University essay from

   Author : Jesper Brovall; [2022-01-13]
   Keywords : Medical physics; Dosimetry; MRI; Radiation therapy;

   Abstract : Background/ purpose: Because of the superior soft tissue contrast, in comparison with computed tomography (CT) data, magnetic resonance imaging (MRI) is of high interest to include in a larger extent in the ra diation therapy (RT) process.

5. 4. 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)

   Author : Viktor Rosenberg; [2022]
   Keywords : Positron emission tomography; image registration; hypoxic tumour volume; dose escalation; tumour control probability;

   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
