1. 2D & 3D phase retrieval for propagation-based X-ray phase-contrast tomography
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : Propagation-based X-ray phase-contrast tomography is a 3d imaging technique that utilizes two-dimensional projections from different angular views $\theta =[0,\pi]$ to reconstruct the 3D object information. The phase-contrast allows for higher feature contrast than conventional transmission tomography, as the phase interference gives rise to a sharp edge contrast. READ MORE

2. Sustaining Orientation of Ubiquitin for Single Particle Imaging Using Electric Fields
University essay from Uppsala universitet/Kemisk och biomolekylär fysik; Uppsala universitet/Energimaterialens fysikAbstract : Single-particle imaging, or SPI, is a method used to obtain the three-dimensional structure of particles. Repeatedly aiming X-rays at samples of a particle produces diffraction patterns, which are combined to a best-fit three-dimensional model of the particle. SPI of proteins can be improved by orienting the protein before imaging. READ MORE

3. Evolution of the Vascular Pattern in Mammals : Using Synchrotron Imaging to Visualise Hidden 3D Structures
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : The morphology and histology of long bones are important tools for understanding tetrapod locomotion and growth. In mammals, the epiphyses of long bones ossify from a secondary centre of ossification. The consensus is that vascular canals are closely tied to the formation of these centres. READ MORE

4. Automatic Body Condition Scoring on Dairy Cows of the Swedish red breed
University essay from SLU/Dept. of Animal Nutrition and ManagementAbstract : The objective of this MSc thesis was to investigate parameters reported to be associated with dairy cows’ body condition and its changes. A valid reference of a dairy cow’s body condition was to be suggested and investigated for suitability in the development of a 3D imaging based automatic body condition scoring model. READ MORE
