  1. 11. Automatic Tissue Segmentation of Volumetric CT Data of the Pelvic Region

    University essay from Linköpings universitet/Medicinsk informatik

    Author : Julius Jeuthe; [2017]
    Keywords : Image segmentation; Computed tomography; Pelvic region; Threshold segmentation; Region growing; Histogram matching; Atlas segmentation; Morphon;

    Abstract : Automatic segmentation of human organs allows more accurate calculation of organ doses in radiationtreatment planning, as it adds prior information about the material composition of imaged tissues. For instance, the separation of tissues into bone, adipose tissue and remaining soft tissues allows to use tabulated material compositions of those tissues. READ MORE

  3. 12. A 3D-ultrasound guidance device for central venous catheter placement using augmented reality

    University essay from KTH/Medicinsk teknik

    Author : Magnus Jansson; [2017]
    Keywords : Augmented Reality; Central Venous Catheterization; Mechanical complications; Guidance system.;

    Abstract : Central venous catheterization (CVC) is performed frequently in clinical practices in Operation Rooms(OR) and Emergency Rooms(ER). CVC is performed for different reasons such as supply nutrition or medicine. For CVC ultrasound (US), diagnostic device is preferable among other medical imaging technologies. READ MORE

  4. 13. Video Processing for Nail-fold Capillary Blood Velocity Detection

    University essay from KTH/Skolan för elektro- och systemteknik (EES)

    Author : Chen Wang; [2015]
    Keywords : Video analysis; nail-fold capillary; blood velocity detection;

    Abstract : Microcirculation plays an essential and functional role in the human body and reflects people’s physical status with microscopic detail. For peripheral microcirculation, nail-fold microscopy is a convenient and non-invasive tool since the capillaries in the nail-fold are well arranged and parallel to the skin, which is advantageous for microscopic visualization.

  5. 14. Volumetric Terrain Genereation on the GPU : A modern GPGPU approach to Marching Cubes

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Ludwig Pethrus Engström; [2015]
    Keywords : GPGPU; Marching Cubes; DirectX; Volumetric Rendering;

    Abstract : Volumetric visualization is something that has become more interesting during recent years. It has been something that was not feasible in an interactive environment due to its complexity in the 3D space. READ MORE

  6. 15. Automatic Segmentation of Tissues in CT Images of the Pelvic Region

    University essay from Linköpings universitet/Institutionen för medicinsk teknik; Linköpings universitet/Tekniska högskolan

    Author : Martin Kardell; [2014]
    Keywords : Image segmentation; Computed tomography; Pelvic region; Prostate; Thresholding; Region growing; Atlas segmentation; Deformable models;

    Abstract : In brachytherapy, radiation therapy is performed by placing the radiation source into or very close to the tumour. When calculating the absorbed dose, water is often used as the radiation transport and dose scoring medium for soft tissues and this leads to inaccuracies. READ MORE
