2. 1. Surface guided radiotherapy

   Author : Malin Kügele; Lund Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface guided radiotherapy; DIBH; SGRT; radiotherapy; patient positioning; intra-fraction motion; surface imaging; treatment planning; SGRT; surface guided radiotherapy; intra-fraction motion; DIBH; patient positioning; treatment planning; surface imaging;

   Abstract : Modern radiotherapy aims to treat the decease while minimizing the radiation dose to the adjacent normal tissue, to minimize acute and late effects of the treatment. The foremost technological approaches have been intensity modulated radiotherapy (IMRT) and intensity modulated proton therapy (IMPT) in combination with image guided radiotherapy (IGRT). READ MORE

4. 2. Verification of dose calculations in radiotherapy

   Author : Tufve Nyholm; Mikael Karlsson; Ben Mijnheer; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiotherapy; dose calculation; quality control; pencil kernel; Radiological physics; Radiofysik;

   Abstract : External radiotherapy is a common treatment technique for cancer. It has been shown that radiation therapy is a both clinically and economically effective treatment for many types of cancer, even though the equipment is expensive. The technology is in constant evolution and more and more sophisticated and complex techniques are introduced. READ MORE

5. 3. Clinical application of intensity and energy modulated radiotherapy with photon and electron beams

   Author : Xiangkui Mu; Björn Zackrisson; Mikael Karlsson; Thomas Björk-Eriksson; Erik Blomquist; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Radiotherapy; IMXT; IMET; IMPT; proton beams; electron beams; treatment planning; cancer induction; side-effects; fraction time; intensity modulated radiotherapy; Onkologi; Oncology; Onkologi; Oncology; onkologi;

   Abstract : 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. READ MORE

6. 4. Rectal cancer : Aspects of surgery and radiotherapy

   Author : Michael Dahlberg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Rectal cancer; surgery; preoperative radiotherapy; local recurrence; survival; adverse effects; cost-effectiveness; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

   Abstract : In rectal cancer, local failure is one of the principle causes of morbidity and mortality. The use of radiotherapy as an adjuvant treatment in resectable rectal cancer is extensively studied in order to lower unacceptably high local failure rates. READ MORE

7. 5. Radiotherapy in a FLASH : Towards clinical translation of ultra-high dose rate electron therapy

   Author : Elise Konradsson; Lund Medicinsk strålningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radiotherapy; Dosimetry; Ultra-high dose rate; Electron therapy; FLASH; Fysicumarkivet A:2023:Konradsson;

   Abstract : FLASH radiotherapy (FLASH-RT) is a promising new approach to radiotherapy that has the potential to transform the field. By administering radiation at ultra-high dose rates (UHDR) on a millisecond timescale, FLASH-RT may increase normal tissue tolerance compared to conventional radiotherapy while maintaining the anti-tumoral effect.
