1. 1. Investigation of above-ground biomass with terrestrial laser scanning : A case study of Valls Hage in Gävle

   University essay from Högskolan i Gävle/Samhällsbyggnad

   Author : Mathias Billenberg; [2023]
   Keywords : TLS; tree species; QSM; AGB; volume; wood density; biomass; allometric; point cloud;

   Abstract : The thesis investigates above-ground biomass (AGB) with terrestrial laser scanning (TLS) for estimating AGB in a study area in Valls Hage, Gävle. The study used TLS for field measurements to collect highly detailed point clouds of two tree species for AGB estimation and comparison against validation data. READ MORE

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Cornelia Säll; [2023]
   Keywords : Medicine and Health Sciences;

   Abstract : Background/purpose Quantitative susceptibility mapping (QSM) is an MRI-based post processing technique to evaluate the magnetic susceptibility, χ, of human tissue using phase data. While brain imaging has been the most common application, other areas have also raised interest. READ MORE

4. 3. MRI-based quantification of magnetic susceptibility: Assessment of measurement and calculation accuracy

   University essay from Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/Sjukhusfysikerutbildningen

   Author : Emma Olsson; [2016]
   Keywords : Medicine and Health Sciences;

   Abstract : An object in an external magnetic field will be magnetized and the degree of magnetization is dependent of the magnetic susceptibility of the object. The local magnetic field inside and around an object in the MR scanner will change due to the magnetization of the object. READ MORE
