  1. 1. The impact of metallic cranial implants on proton-beam radiotherapy treatment plans for near implant located tumours : A phantom study on the physical effects and agreement between simulated treatment plans and the resulting treatment for near implant located cranial tumours

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

    Författare :Adam Sjögren; [2018]
    Nyckelord :Proton-based Radiotherapy; Cranial implants; Titanium implants; Cancer treatment; metal streak artifacts.;

    Sammanfattning : Within the field of radiotherapy treatments of tumour diseases, the hunt for more accurate and effective treatment methods is a continuous process. For some years ion-beam based radiotherapy, especially the proton-beam based applications, has increased in popularity and availability. LÄS MER

  3. 2. Skin dose measurement during radiation therapy of mastectomy patients using GafChromicTM EBT3 films.

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Madeleine Bergström; [2017]
    Nyckelord :Mastectomy; Radiation therapy; GafChromic; EBT3; microcirculation;

    Sammanfattning : Purpose: The aim of this study was to develop a method of measuring changes in the skin microcirculation and skin dose for mastectomy patients in connection with the radiation treatment. The distribution of the skin dose, its dependence on the energy of the beam, field geometry and bolus material and the accuracy of the given skin dose in the treatment planning system were studied.

  4. 3. Measurement of absorbed dose to the skin and its relation with microcircular changes in breast cancer radiotherapy

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Chahed Yacoub; [2016]
    Nyckelord :Radiotherapy; Breast; Microcirculation; Skin;

    Sammanfattning : Radiation therapy has been shown to increase local and regional control as well as overall survival with breast cancer, but the vast majority of patients develop acute skin reactions, which are in part related to microvascular changes. These reactions vary between different skin sites. LÄS MER

  5. 4. The effect of concurrent radiation and calcium in two cancer cell lines

    Master-uppsats, Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Jessica Billberg; [2016]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: Calcium is an important ubiquitous second messenger regarding the maintenance of cellular homeostasis, and is therefore tightly regulated. Calcium induces cell death when internalised into cancer cells after permeabilization of the cell membrane by electroporation. LÄS MER

  7. 5. Measurement of absorbed dose to the skin and its relation with microcircular changes in breast cancer radiotherapy

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Chahed Yacoub; [2016]
    Nyckelord :Radiotherapy; Breast; Microcirculation; Skin; Erythema;

    Sammanfattning : Radiation therapy has been shown to increase local and regional control as well as overall survival with breast cancer, but the vast majority of patients develop acute skin reactions, which are in part related to microvascular changes. These reactions vary between different skin sites. LÄS MER
