  1. 1. 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

  2. 2. Comparing Weak and Strong Annotation Strategies for Multiple Instance Learning in Digital Pathology

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Alice Ciallella; [2022]
    Nyckelord :Multiple-Instance Learning MIL ; prostate cancer; bag creation; digital pathology; binary classification; multiclass classification;

    Sammanfattning : Prostate cancer is the second most diagnosed cancer worldwide and its diagnosis is done through visual inspection of biopsy tissue by a pathologist, who assigns a score used by doctors to decide on the treatment. However, the scoring system, the Gleason score, is affected by a high inter and intra-observer variability, lack of standardization, and overestimation. LÄS MER

  3. 3. Feasibility of single time point dosimetry during 177Lu-PSMA-617 treatments of prostate cancer

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Elias Nilsson; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: Standard dosimetry methods for radionuclide therapies re- quire imaging at multiple time points post injection. An alternative method has been presented in the literature that uses previously acquired pharma- cokinetic data to create so-called dose factors. LÄS MER

  4. 4. Validation of a method utilising MR images for dose planning of prostate cancer treatment : Validation of new coil technology applied on the pelvis region of healthy volunteers

    Master-uppsats, Linköpings universitet/Institutionen för hälsa, medicin och vård

    Författare :Tova Rung; [2022]
    Nyckelord :Synthetic CT; Air coil;

    Sammanfattning : By generating a synthetic CT image (sCT) directly from the MRI, the electron density can be calculated, and the CT examination can be excluded from the patient flow minimizing the risk of uncertainties in the registration. Basing the radiation treatment process solely on MR images is called MRI-only and is beneficial for the patient as it can provide more accurate radiation treatment than the standardised treatment with fewer CT examinations and possibly a more cost-effective radiation treatment process.

  5. 5. Mäns erfarenheter av att leva med diagnostiserad prostatacancer

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för hälsovetenskaper

    Författare :Ariya Senajak; Jessie Valdez; [2022]
    Nyckelord :experiences; prostate cancer; sexual health; suffering; support; erfarenhet; lidande; prostatacancer; sexuell hälsa; stöd;

    Sammanfattning : Bakgrund: Prostatacancer är en av det vanligare cancerformer som drabbar män. Behandlingar som innefattar kirurgisk, cytostatisk, strål- och hormonbehandling orsakar lidande för männen. Sjuksköterskan har som skyldighet att vägleda, motivera och informera männen kring sin sjukdom. LÄS MER
