  1. 1. Automation of robust Pareto front-based radiotherapy treatment planning for prostate cancer patients

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Niklas Eliasson; [2019]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose/objective The main objective was to create a software that automates the process of creating treatment plans used for Pareto front-based dose planning for prostate cancer patients. A second objective/purpose was to add a robustness test to this program to evaluate the effect of prostate movements on the treatment plans. READ MORE

  3. 2. Evaluation of Tomodirect for treatment of thoracic and abdominal cases

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Sara Talozi; [2018]
    Keywords : Medicine and Health Sciences;

    Abstract : Sedan 1970-talet har antalet rapporterade cancerfall dubblerats, dels på grund av förändrade levnadsvanor och dels på grund av bättre screeningmetoder som upptäcker cancern i tidigt skede. Tidig upptäckt av cancern i kombination med utvecklad cancerbehandling har bidragit till att risken för att avlida av cancer har minskat. READ MORE

  4. 3. Theoretical analysis and simulation of microwave-generation from a coaxial vircator

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Martin Hägg; [2017]
    Keywords : HPM; high power microwaves; vircator; virtual cathode oscillator; cst; particle-in-cell; PIC; particle studio; microwave weapon; HPM; high power microwaves; virtual cathode oscillator; HPM; mikrovågor; strålvapen; CST; particle in cell; BAE systems; virkator; strålkälla; högeffekts mikrovågor; koaxiell virkator;

    Abstract : High-power microwave, HPM, systems can be used as non-lethal weapons with the ability to destroy or disturb electronics, by damaging internal circuits and inducing high currents. Today microwave sources are being developed with peak powers exceeding 1 GW, one of these devices is the vircator, a narrowband source which is unique to the HPM community. READ MORE

  5. 4. Dosimetric verification of synthetic CT using Cone Beam CT in an MRI only workflow

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Emilia Palmér; [2017]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and purpose: The MRI only workflow aims to base the treatment planning solely on magnetic resonance imaging (MRI), hence excluding the traditional computed tomography (CT) scan. To do that synthetic computed tomography (sCT) data is generated, replacing the conventional CT data. READ MORE

  6. 5. High-­dose rate intraluminal brachytherapy for oesophageal cancer using MR imaging: A clinical implementation

    University essay from Lunds universitet/Sjukhusfysikerutbildningen; Lunds universitet/Medicinsk strålningsfysik, Lund

    Author : Rrezarta Reci; [2015]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose: The aim of this study was to investigate a new methodology for brachytherapy of oesophageal cancer using magnetic resonance (MR) imaging for treatment planning. That includes finding a suitable oesophageal applicator that can be visualised on MR images and to create dose and fraction schedule that should be used brachytherapy treatments. READ MORE
