1. Evaluation of the DXA radiation environment at Sahlgrenska University Hospital
University essay fromAbstract : 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

2. Assessment of hip deformities during childhood: a combined approach of Machine Learning and Finite Element Analysis
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : Osteoarthritis is a degenerative disease that will cause pain and stiffness in the joint if not treated. One cause of early osteoarthritis in the hip joint is pediatric hip deformities. Hip deformities can occur in different stages of childhood and cause the bones to be misshapen or the hip joint to be dislocated. READ MORE

3. Denoising of Dual Energy X-ray Absorptiometry Images and Vertebra Segmentation
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Dual Energy X-ray Absorptiometry (DXA) is amedical imaging modality used to quantify bone mineral density and to detect fractures. It is widely used due to its cheap cost and low radiation dose, however it produces noisy images that can be difficult to interpret for a human expert or a machine. READ MORE

4. Deep Learning to Predict Hip Fracture Risk from Clinical DXA-images
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : Osteoporosis is a bone disease that is defined as low bone mineral density (BMD) and results in an increased risk of bone fracture. It is a serious public health problem that causes excess mortality and major economical and social impact. Today there are more than 8.9 million fractures connected to low bone mineral density worldwide. READ MORE

5. Material Identification using Multiple X-Ray Absorptiometry
University essay from KTH/Numerisk analys, NAAbstract : Dual Energy X-ray Absorptiometry is a proven technique used to identify unknown materials, by measuring the transmission of two X-ray energies. This technique is limited to measuring a single chemical quantity and is not able to handle more chemical variation. To overcome this, one approach is to use multiple-energies to resolve more information. READ MORE
