    Sammanfattning : 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. LÄS MER

  3. 2. Image-driven simulation of brain tumors using a reaction-diffusion mathematical model

    Master-uppsats, Linköpings universitet/Avdelningen för medicinsk teknik

    Författare :Kristos Qiqi; [2023]
    Nyckelord :brain tumor; cancer; mathematical model; simulation; magnetic resonance images; hjärntumör; cancer; matematisk model; simulering; magnetresonanstomografi bilder;

    Sammanfattning : Brain tumors pose a big challenge in the field of neuro-oncology. Gliomas are the largest subgroup. Magnetic resonance imaging is a non-invasive tool for detecting and characterizing these tumors. Mathematical models, such as the reaction-diffusion equation, can be used for understanding the intricate behavior of gliomas. LÄS MER

  4. 3. Ultrasound neural style transfer using domain specific features

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Madelene Alanenpää; [2023]
    Nyckelord :;

    Sammanfattning : Ultrasound imaging is a widely used fast, low-cost, and non-invasive modality for monitoringfetal development during pregnancy and identifying potential problems or other injuries.However, interpreting the images may be difficult due to the noisy appearance and requiresextensive training of sonographers.

  5. 4. Predicting Gastrointestinal Adverse Events in Dogs Treated with Chemotherapeutic Medication

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Emmie Andersdotter; [2023]
    Nyckelord :calprotectin; cancer; canine; chemotherapy; cytostatic medication; dog; gastrointestinal toxicity; gastrointestinal adverse events; gut microbiota; influential factors; questionnaire;

    Sammanfattning : Despite significant advances in the treatment of cancer in canine patients, gastrointestinal toxicity still remains a relatively common finding after chemotherapeutic treatment. These adverse events may cause a fundamental reduction in the patient’s quality of life. LÄS MER

  7. 5. Flash Pulse Thermography Measurements of Coat Thickness

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Alexander Häggkvist; [2023]
    Nyckelord :Flash Pulse Thermography; Power Function; Dynamical Thermal Tomography;

    Sammanfattning : The application of varnish, metal coats, and paint is a common practice for modifying or enhancing material properties. Metal coats are frequently used as protective layers against corrosion, heat, and wear, while also influencing characteristics like conductivity, weight, and production costs. LÄS MER
