   Sammanfattning : In modern, advanced radiotherapy (e.g. intensity modulated photon radiotherapy, IMXT) the delivery time for each fraction becomes prolonged to 10-20 minutes compared with the conventional, commonly 2-5 minutes. The biological effect of this prolongation is not fully known. LÄS MER

4. 3. The virtual tumour - in silico modelling of tumour vasculature, oxygenation and treatment outcome

   Författare :Filippo Schiavo; Iuliana Toma-Daşu; Emely Kjellsson Lindblom; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Medical Radiation Physics; medicinsk strålningsfysik;

   Sammanfattning : Poor tumour oxygenation, namely hypoxia, is one of the major challenges that has been recognised in radiotherapy, yet it is not being accounted for in standard treatments. Hypoxia, resulting from a heterogeneous distribution of vessels (chronic hypoxia) or of a loss in vascular perfusion (acute hypoxia), affects all kinds of solid tumours to different extents. LÄS MER
