  1. 1. Robustness Analysis of Perfusion Parameter Calculations

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alicia Palmér; [2024]
    Keywords : Perfusion; Medical image analysis; Dynamic Contrast Enhanced Magnetic Resonance Imaging; Tofts model; Functional imaging; Optimization; T1 map; Perfusion; Medicinsk bildanalys; Dynamisk kontrastförstärkt magnetisk resonanstomografibildtagning; Tofts-modell; Funktionell bildbehandling; Optimering; T1 karta;

    Abstract : Cancer is one of the most common causes of death worldwide. When given optimal treatment, however, the risk of severe illness may greatly be reduced. Determining optimal treatment in turn requires evaluation of disease progression and response to potential, previous treatment. READ MORE

  2. 2. Enhancing person re-identification: leveraging DensePose for improving occlusion handling and generalization

    University essay from Lunds universitet/Matematik LTH

    Author : Björn Elwin; Anton Fredriksson; [2023]
    Keywords : Mathematics and Statistics;

    Abstract : In this master’s thesis we propose a DensePose-based person re-identification (re-ID) machine learning algorithm building upon previous research on this topic. DensePose, a deep neural network that performs human body part segmentation on images, forms the foundation of our approach. READ MORE

  3. 3. Dynamic Torque Control of Brushed DC Motors for Hardware-in-the-Loop Integration

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Eric Schyllert; [2023]
    Keywords : Technology and Engineering;

    Abstract : The main goal with the thesis was to design, construct and evaluate a system able to drive and brake a mechanical axis to simulate loads and stored rotational energy - a hardware force simulator. The force simulator was then to be integrated in a existing hardware-in-the-loop testing rig to enhance the mechanical dynamics of door simulations. READ MORE

  4. 4. Centennial Climate Variability

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Thomas Askjær; [2022]
    Keywords : Climate variability; paleoclimate; climatemodelsimulations; proxyrecords; spectralanalysis; model proxycomparison;

    Abstract : Throughout earths history, the climate have always naturally varied due to both external forcings and internal mechanisms. With the outlook on future climate change, it is important to understand the climate system and this includes its natural variability. Depending on the driving mechanisms, the variability happens over different timescales. READ MORE

  5. 5. 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

    University essay from Linköpings universitet/Institutionen för hälsa, medicin och vård

    Author : Tova Rung; [2022]
    Keywords : Synthetic CT; Air coil;

    Abstract : 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.
