  1. 1. 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

  3. 2. 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. 3. Detection of relapses after treatment for parotid gland carcinoma: the value of post treatment surveillance

    Master-uppsats, Örebro universitet/Institutionen för medicinska vetenskaper

    Författare :Cajsa Naess; [2021]
    Nyckelord :Salivary gland cancer; Parotid Cancer; Relapse; Surveillance; Survival;

    Sammanfattning : Introduction: Salivary glands are exocrine organs that produce and secrete saliva into theoral cavity. Cancer in the salivary glands is a rare but fatal disease with a five- year survivalrate of 75%. Cancer in the parotid glands, the largest salivary glands, affects about 100persons every year in Sweden. LÄS MER

  5. 4. Intensity Modulated Proton Therapy (IMPT) - A comparative treatment planning study

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Malin Ericsson; [2007]
    Nyckelord :Nukleärmedicin; Medicine and Health Sciences;

    Sammanfattning : Purpose: To study Intensity Modulated Proton Therapy (IMPT) with a new treatment planning optimization software. The aim was also to make a comparative study between existing conventional photon plans, Intensity Modulated X-ray Therapy (IMXT) plans and IMPT plans for three different cancer diagnoses. LÄS MER

  7. 5. Intensity Modulated Radiotherapy Treatment Planning with OTP/TMS for Head&Neck Carcinomas in the ARTSCAN study

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Petra Ambolt; [2004]
    Nyckelord :Strålterapi; Medicine and Health Sciences;

    Sammanfattning : Cancer är en otrevlig sjukdom, som drabbar många människor. Man söker ständigt nya och bättre sätt att bota patienter eller åtminstone lindra sjukdomens framfart. Ett vanligt sätt att behandla cancer är med strålning. Strålningen kan bestå av sk fotoner. LÄS MER
