   Sammanfattning : Bakgrund Gynekologisk cancer drabbar många kvinnor globalt och är ett samlingsnamn för äggstockscancer, vulvacancer, livmoderhalscancer och livmodercancer. Vanliga behandlingsmetoder inkluderar strålbehandling, cellgiftsbehandling (cytostatika) och kirurgi. LÄS MER

3. 17. Influencing factors of posttraumatic growth in breast cancer patients : A descriptive literature review

   Kandidat-uppsats, Högskolan i Gävle/Avdelningen för vårdvetenskap

   Författare :Caizhen Huang; Yueyan Qian; [2023]
   Nyckelord :;

   Sammanfattning : WHO(2015) claimed that breast cancer is the most common cancer among women in developed andless developed countries. The number of women diagnosed is much higher in high-income countries likedeveloped countries than in low- and middle-income countries like developing countries, in part becauseearly detection programs are better in developed countries than in developing countries, and becausedeveloping countries lack health care resources and infrastructure, which makes breast cancer treatment achallenge(Taurin & Alkhalifa, 2020).

4. 18. Generating Synthetic CT Images Using Diffusion Models

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Salih Saleh; [2023]
   Nyckelord :Machine learning; artificial intelligence; generative models; diffusion models; MRI; CT; synthetic CT; radiation therapy;

   Sammanfattning : Magnetic resonance (MR) images together with computed tomography (CT) images are used in many medical practices, such as radiation therapy. To capture those images, patients have to undergo two separate scans: one for the MR image, which involves using strong magnetic fields, and one for the CT image which involves using radiation (x-rays).

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

   Master-uppsats,

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

   Sammanfattning : 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. In an MRI only workflow, the CT scan is excluded and a synthetic CT is used for treatment plan ning. LÄS MER

7. 20. STANDARDIZED ORGAN AT RISK VOLUME FOR EXTERNAL BEAM RADIATION THERAPY IN PROSTATE CANCER AND ITS RELATIONSHIP TO VOLUMES DEFINED BY CLINICAL PRACTICE

   Master-uppsats,

   Författare :Dang Thao; [2022-01-13]
   Nyckelord :Medical physics; Radiation therapy; Prostate cancer; Organs at risk;

   Sammanfattning : Background/ Purpose: In radiation therapy (RT), the radiation dose calculated in tumours and normal tissue depends on how the volumes are defined. It is difficult to standardize how tumour volumes should be defined because their anatomical extension can differ greatly between individuals. LÄS MER
