  1. 11. SBRT of large tumors and tumors located near organs at risk in the thoracic cavity

    Författare :Vitali Grozman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Stereotactic Body Radiotherapy (SBRT) is a non-invasive ablative radiation therapy developed at Karolinska University Hospital in the early 90-s. Its basic principles are highly focused inhomogeneous dose load with rapid fall of in the periphery of the target, delivered in few fractions with high-doses per fraction. LÄS MER

  3. 12. A Novel Approach for Radiotherapy and Radiosurgery Treatment Planning Accounting for High-Grade Glioma Invasiveness into Normal Tissue

    Författare :Wille Häger; Iuliana Toma-Daşu; Marta Lazzeroni; Jesper Kallehauge; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tumor modeling; medical physics; model; simulation; glioblastoma; gbm; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : High-grade gliomas (HGGs) are a type of malignant brain cancer, which include glioblastomas (GBMs). In adults, GBM is the most common malignant primary brain cancer. Attempts to treat patients with GBMs have been conducted for over a century, but the prognosis has only marginally improved. LÄS MER

    Sammanfattning : Rolandic epilepsy (RE) is the most common focal epilepsy syndrome in the pediatric age group with an onset between 3 and 13 years. The syndrome is defined by electro-clinically typical features and has been considered benign according to seizure remission before the age of 16 years. LÄS MER

  5. 14. Seismic Exploration Solutions for Deep-Targeting Metallic Mineral Deposits : From high-fold 2D to sparse 3D, and deep-learning workflows

    Författare :Magdalena Markovic; Alireza Malehmir; Gilles Bellefleur; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Exploration; Seismic; Mineral Deposits; Diffraction; Deep learning;

    Sammanfattning : Mineral exploration has in recent years moved its focus to greater depths than ever before, particularly in brown fields. Exploring new deposits at depth, if economical, would not only expand the life of mine but also provide minimal environmental impacts. It allows the existing mining infrastructures to be used for a longer period. LÄS MER

  7. 15. Validation of Phase Contrast Flow Quantification and Relaxometry for Cardiovascular Magnetic Resonance Imaging

    Författare :Sebastian Bidhult; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :;

    Sammanfattning : Quantitative imaging, where every pixel of an image represents a physical quantity (e.g. timeor velocity) is being increasingly used in the field of diagnostic radiology and has potential toenhance medical diagnosis. LÄS MER
