2. 1. When children undergo radiotherapy. Exploring care, developing and testing preparation procedures

   Author : Jenny Gårdling; Barns och familjers hälsa; []
   Keywords : Radiotherapy; Children; Parents; Radiotherapy nurses; Information; Preparation; Anxiety; General Anaesthesia;

   Abstract : Radiotherapy (RT) is a repetitive treatment divided into daily fractions, scheduled five days a week from one up to several weeks depending upon the child’s diagnosis. Although RT is painless and non-invasive, children experience anxiety. READ MORE

4. 2. Optimising Radiotherapy in Rectal Cancer Patients

   Author : Calin Radu; Bengt Glimelius; Åke Berglund; Lars Påhlman; Ragnar Hultborn; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rectal cancer; locally advanced; radiotherapy; FDG-PET; peripheral boost; protons; quality-of-life; Oncology; Onkologi;

   Abstract : Rectal cancer is the eight most common cancer diagnosis in Sweden in both men and women, with almost 2000 new cases per year. Radiotherapy, which is an important treatment modality for rectal cancer, has evolved during the past decades. READ MORE

5. 3. Radiation Oncology Data and Modelling Side Effects after Radiation Therapy

   Author : Caroline Olsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dose and side effect data; dose-volume response; fractionation effect; LQ model; sequential two-phase radiotherapy; head and neck cancer; parotid gland; xerostomia; pelvic radiotherapy; gynecological cancer; pubic bone; pain; data integration; xerostomia;

   Abstract : Although modern radiation therapy techniques have the ability to conform the dose distribution of ionizing radiation tightly around the volume to be treated, unwanted irradiation to surrounding organs remains a problem. The probability of a side effect arising in the normal tissue of a patient after radiation therapy can be modelled by sigmoid mathematical functions known as normal tissue complication probability (NTCP) models.

6. 4. Geometric distortions in MRI based radiotherapy and PET/MRI

   Author : Josef Lundman; Tufve Nyholm; Anne Larsson; Jörgen Olofsson; Marco Riboldi; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; MRI; PET MR; PET MRI; medical imaging; radiotherapy; geometrical distortions; MR-only; MRI-only; radiofysik; radiation physics;

   Abstract : Magnetic resonance imaging (MRI) offers high soft-tissue contrast compared to computed tomography (CT). This contrast is helpful in many cases, not least for delineating tumours for radiotherapy treatment, and has led to increasing use in radiotherapy treatment planning (RTP). READ MORE

7. 5. Quality assurance for magnetic resonance imaging (MRI) in radiotherapy

   Author : Mary Adjeiwaah; Tufve Nyholm; Rob HN Tijssen; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic resonance imaging; Radiotherapy; geometric distortions; patient-induced susceptibilities MR-only; radiofysik; radiation physics;

   Abstract : Magnetic resonance imaging (MRI) utilizes the magnetic properties of tissues to generate image-forming signals. MRI has exquisite soft-tissue contrast and since tumors are mainly soft-tissues, it offers improved delineation of the target volume and nearby organs at risk. READ MORE
