  1. 1. A Novel Method for Finding Overlap Depth : Development of ArtiaX, a ChimeraX plugin

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Gunnar Arctaedius; [2023]
    Keywords : Cryo-electron tomography; image processing; surface visualization; overlap measurement; normal projection method; Kryoelektrontomografi; bildbehandling; ytvisualisering; överlapsmätning; normalprojektionsmetoden;

    Abstract : Visualization and image filtering are important parts of cryo-electron tomography analysis. ArtiaX, a plugin developed for UCSF ChimeraX, has been extended to improve the functionality of these two parts. For the visualization, a method of moving 3D surfaces to remove overlap between them has been developed and implemented. READ MORE

  3. 2. Dynamic Real-Time Fire Propagation for Networked Multiplayer Games

    University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Author : Iris Kotsinas; Viktor Tholén; [2022]
    Keywords : fire simulation; fire propagation; fire; game system; real-time; dynamic system; multiplayer games;

    Abstract : Simulating fire propagation in games can be problematic since it requires immense computational power if the fire is portrayed physically accurate. To decrease the computational power required, simplifications and approximations must be made. READ MORE

  4. 3. Optimisation of image acquisition and reconstruction of 111In-pentetrotide SPECT

    University essay from Radiofysik

    Author : Daniel Holmberg; [2012]
    Keywords : Radiation Science; Nuclear Medicine; SPECT; OSEMS; Image analysis; MLEM; Radiation Physics; 111-In; Pentetrotide; Monte Carlo; ESSE; OSEMS;

    Abstract : The aim of this study is to optimise the acquisition and reconstruction for SPECT with 111In- pentetrotide with the iterative reconstruction software OSEMS. For 111In-pentetrotide SPECT, the uptake in the tumour is usually high compared to uptake in normal tissue. READ MORE

  5. 4. Effects of slabbing and slice thickness on image reading time and micro calcification detection in breast tomosynthesis

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Martin Andersson; [2011]
    Keywords : Röntgen; Medicine and Health Sciences;

    Abstract : Breast tomosynthesis (BT) is a new X-ray modality that reconstructs the breast volume in many slices instead of, as in mammography, showing a single 2D projection of the breast. The slice thickness is typically 1 mm for clinically used BT-units. READ MORE

  6. 5. Utvärdering av radiologiska kriterier för att bedöma tillståndet ileus på hund

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Charlotta von Delwig; [2006]
    Keywords : ileus; hund; diagnostik; metod; smådjur; radiologi; röntgen;

    Abstract : Dogs presenting with vomiting and abdominal pain, are common patients at the small animal clinic, and the reason for these symptoms can have various aetiologies. One common reason for these symptoms is obstruction of the small intestine caused by a foreign body. READ MORE
