    Sammanfattning : Construction of radiotherapy treatments for cancer is a laborious and time consuming task. At the same time, when presented with a treatment plan, an oncologist can quickly judge whether or not it is suitable. This means that the problem of constructing these treatment plans is well suited for automation. LÄS MER

  4. 3. Beräkning av bendensitet och benvolym vid datortomografisk helkroppsundersökning av katt : jämförelse av två metoder för beräkning samt inverkan av storlek, ålder, kön och osteoartrit

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

    Författare :Stefan Lindén; [2020]
    Nyckelord :katt; bendensitet; benvolym; datortomografi; benvolym; ålder; kön; storlek; felin osteoartrit;

    Sammanfattning : Bone volume and bone density may be affected by disease. Measurement of bone volume and bone density in cats could possibly be used as a tool in diagnosing osteoarthritis (OA), lameness and other diseases expected to affect bone density and bone volume. Measurement of bone volume is also useful when evaluating body composition. LÄS MER
