  1. 21. Image Similarity Scoring for Medical Images in 3D

    University essay from Linköpings universitet/Datorseende

    Author : Felicia Castenbrandt; [2022]
    Keywords : CT; Medical Image Processing; Similarity Scoring;

    Abstract : Radiologists often have to look through many different patients and examinations in quick succession, and to aid in the workflow the different types of images should be presented for the radiologist in the same manner and order between each new examination. Thus decreasing the time needed for the radiologist to either find the correct image or rearrange the images to their liking. READ MORE

  3. 22. COMPARISON OF MULTI-CRITERIA OPTIMIZATION IN TWO DIFFERENT TREATMENT PLANNING SYSTEMS

    University essay from

    Author : Anna Lindström; [2021-05-10]
    Keywords : Medical physics; Multi-criteria optimization; Pareto front; volumetric modulated arc therapy; head and neck cancer; prostate cancer;

    Abstract : Purpose: The purpose with this study was to compare multi-criteria optimization (MCO) for volumetric modulated arc therapy (VMAT) treatment plans in two different treatment planning systems. Theory: When performing treatment planning prior to radiation therapy it is important to prioritize between absorbed dose to target and absorbed dose to organs at risk (OAR). READ MORE

  4. 23. Temporal Multivariate Distribution Analysis of Cell Shape Descriptors

    University essay from Umeå universitet/Institutionen för fysik

    Author : Amanda Krantz; [2021]
    Keywords : ;

    Abstract : In early drug discovery and the study of the effects of new chemical compounds on cancer cells, the change in cell shape over time provides vital information about cell health. Live-cell image analysis systems can be used to extract cell-shape describing parameters of individual cells during exposure to new drugs. READ MORE

  5. 24. Modelling of the DNA Helix’s Duration for Genome Sequencing

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sabina Dzubur; Rim Sharif; [2021]
    Keywords : Nanopore sequencing; DNA sequencing; Linear regression; Supervised learning; Distribution fit;

    Abstract : Nanopore sequencing is the next generation ofsequencing methods which promises to deliver cheaper andmore portable genome sequencing capabilities. A single DNAor RNA strand is passed through a nanopore nested in anartificial membrane with an electric potential applied across it. READ MORE

  6. 25. The effect of noise filters on DVS event streams : Examining background activity filters on neuromorphic event streams

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Giorgos Trogadas; Larissa Ekonoja; [2021]
    Keywords : Dynamic vision sensor; Noise reduction; Filter performance evaluation; Histogram of Averaged Time Surfaces; Neuromorphic vision; Event-based vision; Dynamisk synsensor; Brusreducering; Utvärdering av filter prestanda; Histogram av genomsnittliga tidsytor; Neuromorfisk synsensor; Händelsebaserad syn;

    Abstract : Image classification using data from neuromorphic vision sensors is a challenging task that affects the use of dynamic vision sensor cameras in real- world environments. One impeding factor is noise in the neuromorphic event stream, which is often generated by the dynamic vision sensors themselves. READ MORE
