1. 1. Modelling and design approaches of magnetostrictive actuators

   Författare :Mattias Oscarsson; Göran Engdahl; Tord Cedell; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetostriction; Terfenol; Coil optimisation; Leakage flux; Modelling tools; Eddy currents; Magnetostriktion; Electrical engineering; Elektroteknik;

   Sammanfattning : A magnetostrictive material elongates when it is subjected to a magnetic field. This effect can then be used to design powerful actuators. LÄS MER

3. 2. Measurement accuracy. Applications in X-ray computed tomography (CT) dose reduction and magnetic resonance spectroscopy (MRS) volume selection

   Författare :Göran Starck; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT; Radiation exposure; Image quality; Tissue characterisation; MRS volume selection; Signal profile; Phantom; Magnetic susceptibility;

   Sammanfattning : X-ray computed tomography (CT) images of transaxial cross sections of the body can be used to determine tissue volumes. However, the considerable radiation dose associated with high-quality clinical images has greatly limited the use of CT for this application. LÄS MER
