  1. 26. Clinical evaluation of atlas based segmentation for radiotherapy of prostate tumours

    University essay from Institutionen för fysik

    Author : Christoffer Granberg; [2011]
    Keywords : segmentation; registration; radiotherapy; atlas;

    Abstract : Abstract   Background Semi-automated segmentation using deformable registration of atlases consisting of pre-segmented patient images can facilitate the tedious task of delineating structures and organs in patients subjected to radiotherapy planning. However, a generic atlas based on a single patient may not function well enough due to the anatomical variation between patients. READ MORE

    Keywords : MRI; Medicine and Health Sciences;

    Abstract : Introduction: Regional and global brain volumes are of great interest in many different research projects, not least in Alzheimer’s research. The purpose of this project is to optimize the MPRAGE sequence for automatic and repeatable segmentation of human brain tissue. READ MORE

  6. 30. Automatic landmark detection on Trochanter Minor in x-ray images

    University essay from Institutionen för systemteknik

    Author : Per Holm; [2005]
    Keywords : Technology; trochanter minor; landmark; edge detection; image processing; segmentation; TEKNIKVETENSKAP;

    Abstract : During pre-operative planning for hip replacement, the choice of prosthesis can be aided by measurements in x-ray images of the hip. Some measurements can be done automatically but this require robust and precise image processing algorithms which can detect anatomical features. The Trochanter minor is an important landmark on the femoral shaft. READ MORE
