  1. 16. Detection and Segmentation of Brain Metastases with Deep Convolutional Networks

    University essay from KTH/Datorseende och robotik, CVAP

    Author : Max Losch; [2015]
    Keywords : deep learning; cnn; convnets; convolutional neural networks; metastases; computer vision; brain tumor; medical imaging; mri;

    Abstract : As deep convolutional networks (ConvNets) reach spectacular results on a multitude of computer vision tasks and perform almost as well as a human rater on the task of segmenting gliomas in the brain, I investigated the applicability for detecting and segmenting brain metastases. I trained networks with increasing depth to improve the detection rate and introduced a border-pair-scheme to reduce oversegmentation. READ MORE

  3. 17. Angiogeneshämmare som behandling mot metastaser : var forskningen är idag och vart den är på väg

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

    Author : Carl Johan Grevby; [2013]
    Keywords : tumör; angiogenes; metastasering; angiogeneshämmare;

    Abstract : Syftet med denna litteraturöversikt är att göra en utvärdering över de mekanismer som är viktiga vid tumörmetastasers nybildning av kärl s.k. angiogenes och med vilka metoder man kan hindra dem. READ MORE

  4. 18. Robustness of the voluntary breath-hold approach for the treatment of early stage lung cancer with spot scanned proton therapy

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Jenny Dueck; [2013]
    Keywords : Medicine and Health Sciences;

    Abstract : Background: Intra- and interfractional variations in anatomy can cause unplanned substantial alterations of the dose distribution of the target in proton therapy. Motion management methods might be used in order to minimize anatomical variations. READ MORE

  5. 19. 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

  6. 20. Volumetric Quantification of Metastatic Burden from SPECT/CT Images

    University essay from Lunds universitet/Matematik LTH

    Author : Hanna Carlsson; [2012]
    Keywords : Technology and Engineering;

    Abstract : Bone scintigraphy images are used to investigate the presence of metastases in patients with prostate cancer. An analysis of these images indicates the proportion of cancer in the bones; the Bone Scan Index (BSI). This value is an important prognostic factor used to predict the future for the patients.
