  1. 1. Emphysema Classification via Deep Learning

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Olov Molin; [2023]
    Keywords : Deep learning; emphysema; CNN;

    Abstract : Emphysema is an incurable lung airway disease and a hallmark of Chronic Obstructive Pulmonary Disease (COPD). In recent decades, Computed Tomography (CT) has been used as a powerful tool for the detection and quantification of different diseases, including emphysema. The use of CT comes with a potential risk: ionizing radiation. READ MORE

  2. 2. Evaluation of Computer Tomography based Cancer Diagnostics with the help of 3D Printed Phantoms and Deep Learning

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Alex Back; Pontus Pandurevic; [2023]
    Keywords : Machine Learning; Deep Learning; Convolutional Neural Networks; Perception Loss; CNN; DL; ML; Computer Tomography; CT; Cancer Diagnostics; Evaluation of Image Reconstruction; Radiomics; Tumors; 3D Printed Phantoms; 3D Printing; PLA;

    Abstract : Computed x-ray tomography is one of the most common medical imaging modalities andas such ways of improving the images are of high relevance. Applying deep learningmethods to denoise CT images has been of particular interest in recent years. READ MORE

  3. 3. Evaluation of the DXA radiation environment at Sahlgrenska University Hospital

    University essay from

    Author : Saga Söderholm; [2022-05-18]
    Keywords : Medical physics; DXA; DEXA; Dual-energy X-ray absorptiometry; Bone mineral density;

    Abstract : Purpose: The aims of this work were to evaluate the radiation environment in the dual-energy X-ray absorptiometry (DXA) rooms at Sahlgrenska University Hospital, estimate personnel doses, determine legal requirements for DXA personnel, examine the operators’ view on radiation safety and develop material with dose information for patients and operators. Theory: DXA is a low dose X-ray modality mainly used in osteoporosis examinations, for which it is considered the reference technique. READ MORE

  4. 4. Actin filaments as an indicator of impaired neuronal differentiation mediated by disruption of the retinoic acid signalling pathway

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Hanin Salloum; [2022]
    Keywords : Retinoic acid; actin; cytoskeleton; neural progenitor C17.2 cells; neuron; Coronin 1C; Cdc42 Cdc42 effector protein 4 gene ; Fn1 Fibronectin ; Wnt pathway.;

    Abstract : Retinoic acid (RA) is a well-known neurodevelopmental signaling molecule. It is reported to induce effects on neurite formation in differentiating neurons and to interfere with the actin cytoskeleton. Therefore, this project aimed to investigate the mechanisms behind effects of RA on the actin cytoskeleton of developing neurons using the C17. READ MORE

  5. 5. Improving antibody-based immunotherapy protocols in vitro : Study on optimization of antitumor immunity by antibody-dependent phagocytosis with the monoclonal antibody rituximab

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Giovanni Ferro; [2022]
    Keywords : ;

    Abstract : The monoclonal antibody Rituximab (RTX) has been widely and successfully used to treat non-Burkitt B cell lymphoma in human patients. The combination of immunotherapy with low-dose chemotherapy has increased the success of the treatment and translated into increased patients’ survival. READ MORE
