1. 11. Deep Learning-Based Skeleton Segmentation for Analysis of Bone Marrow and Cortical Bone in Water-Fat Magnetic Resonance Imaging

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Adham Belbaisi; [2021]
   Nyckelord :Water-fat MRI; UK Biobank; Deep learning; Skeleton segmentation; Bone marrow; Cortical bone;

   Sammanfattning : A major health concern for subjects with diabetes is weaker bones and increased fracture risk. Current clinical assessment of the bone strength is performed by measuring Bone Mineral Density (BMD), where low BMD-values are associated with an increased risk of fracture. LÄS MER

3. 12. Grafting materials for alveolar cleft reconstruction -a systematic review

   Master-uppsats, Malmö universitet/Odontologiska fakulteten (OD)

   Författare :Pegah Mirdamadian; Raha Salahshour Nargi; [2021]
   Nyckelord :cleft palate; cleft lip; secondary alveolar bone grafting; alveoloplasty; oral surgery; autologous bone graft; bone substitute material; computerized tomography; bone volume; bone height; systematic review;

   Sammanfattning : Aim: The aim of this literature study was to systematically review the scientific evidence on the most effective donor sites and/or bone substitute material for secondary alveolar cleft grafting in alveolar cleft patients. Material and method: In order to acquire a systematic and transparent reporting this literature review was conducted according to the PRISMA statement. LÄS MER

4. 13. Beräkning av bendensitet och benvolym vid datortomografisk helkroppsundersökning av katt : jämförelse av två metoder för beräkning samt inverkan av storlek, ålder, kön och osteoartrit

   Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

   Författare :Stefan Lindén; [2020]
   Nyckelord :katt; bendensitet; benvolym; datortomografi; benvolym; ålder; kön; storlek; felin osteoartrit;

   Sammanfattning : Bone volume and bone density may be affected by disease. Measurement of bone volume and bone density in cats could possibly be used as a tool in diagnosing osteoarthritis (OA), lameness and other diseases expected to affect bone density and bone volume. Measurement of bone volume is also useful when evaluating body composition. LÄS MER

5. 14. Practical implementation and exploration of dual energy computed tomography methods for Hounsfield units to stopping power ratio conversion

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Medicinsk strålningsvetenskap

   Författare :David Kennbäck; [2018]
   Nyckelord :computed tomography; CT; dual energy; DECT; dual energy computed tomography; dual energy CT; HU; SPR; Skandion; Skandionkliniken; Hounsfield; Hounsfield unit; Stopping power ratio;

   Sammanfattning : The purpose of this project was to explore the performance of methods for estimating stopping power ratio (SPR) from Hounsfield units (HU) using dual energy CT scans, rather than the standard single energy CT scans, with the aim of finding a method which could outperform the current single energy stoichiometric method. Such a method could reduce the margin currently added to the target volume during treatment which is defined as 3. LÄS MER

7. 15. Extraction of Follow up Parameters of Bone Density Microwave Sensor from Post Craniotomy and Lower Extremity Trauma Rehabilitation Measurements

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :George George Thomas; [2017]
   Nyckelord :;

   Sammanfattning : Longitudinal microwave based sensor systems facilitates frequent follow ups in scenarios where healing information is largely missing. An example is neonatalcraniotomy where Computerized Tomography (CT) information is available mostly before surgery and up to three years after that. LÄS MER
