2. 11. Optimizing computed tomography : quality assurance, radiation dose and contrast media

   Author : Patrik Nowik; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Computed tomography (CT) is an important modality in radiology; it enables imaging of the inside of patients without superimposed anatomy. The radiation dose and quality of a CT image are highly dependent on the CT scanner, the scan settings and, if applicable, the timing and dosage of the intravenous contrast media (CM). READ MORE

4. 12. Influence of lifestyle behaviours on bone mineral density among young healthy women: A two-year study. A Tentative Salutary Model

   Author : Carina Elgán; Institutionen för hälsovetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; grounded theory; follow-up; Skeleton; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi; multiple triangulation; stress; time spent outdoors; sleep; salutogenic; bone resorption; bone mineral density; Young healthy women; lifestyle;

   Abstract : The overall aim of this prospective observational study with a salutogenic approach was to investigate bone mineral density (BMD) and BMD changes in the heel bone, in a group of healthy women, in relation to physiological factors and lifestyle behaviours over a two-year period as well as investigating the women’s view of their lifestyle behaviours. Data were collected in 1999 (T1) and 2001 (T2). READ MORE

   Author : Anette Karlsson; Magnus Borga; Anneli Peolsson; Janne West; Todd Parrish; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Muscle Composition; Muscle fat Infiltration; Magnetic Resonance Imaging;

   Abstract : Changes in muscle tissue composition, e.g. decrease in volume and/or increase of fat infiltration, are related to adverse health conditions such as sarcopenia, inflammation, muscular dystrophy, and chronic pain. READ MORE

6. 14. A Measurement Approach to some Robot Related Issues : Robot Safety, Robot Control Tool and Robot Object Recognition

   Author : Nils Karlsson; Jouko Suokas; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The research of the measurement group at Linköping university has for some time been focused on the role of measurements in robotics. The main objective of the group's research work has been to provide the robot with sensor information in order to increase its autonomy. READ MORE

7. 15. Ultrasound Contrast Agents Loaded with Magnetic Nanoparticles : Acoustic and Mechanical Characterization

   Author : VeeraVenkata Satyanarayana Kothapalli; Lars-Åke Brodin; Jan Engvall; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound contrast agents; SPION nanoparticles; harmonic oscillation; backscattering power; attenuation coefficient; phase velocity; nonlinear equation of motion;

   Abstract : The current methodologies in body scanning diagnostic uses different simultaneous imaging modalities like Ultrasound (US), magnetic resonance imaging (MRI), single photon emission tomography (SPECT) and positron emission tomography (PET). The field requires combination of different modalities for effective use in clinical diagnostics. READ MORE
