  1. 21. Correlation between PET/MRI image features andpathological subtypes for localized prostate cancer

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Jens Lindahl; [2021]
    Nyckelord :MRI; PET; Image features; Image processing; Localized prostate cancer; Pathological subtypes; MR; PET; Bildegenskaper; Bildbehandling; Lokal prostata cancer; Patologiska undertyper;

    Sammanfattning : Prostate cancer is the most common cancer in Sweden. Patients with the condition have a good prognosis in general and most cases can be treated. LÄS MER

  3. 22. Design of a Polygeneration system in Filipinas ETCR, Colombia

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Germán Ropero Pérez; [2021]
    Nyckelord :;

    Sammanfattning : This project has addressed the design of a cost-effective Polygeneration system that guarantees a continuous, equitable and environmentally friendly energy supply for the rural settlement of Filipinas ETCR, (in Spanish, Espacios Territoriales de Capacitación y Reincorporación) Colombia, which is currently not achieved, due to a system that relies on the national electricity grid (with numerous outages) and on LPG (Liquefied Petroleum Gas) and wood to meet the thermal demand, mainly for cooking. For this purpose, in addition to the current energy supply situation, the energy demand according to type (electricity and heat) and sector (residential, commercial and agro-livestock) is characterized.

  4. 23. Clinical dose feature extraction for prediction of dose mimicking parameters

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Anton Finnson; [2021]
    Nyckelord :Radiation therapy; feature extraction; wavelets; treatment planning; dose mimicking; variational autoencoder; Strålterapi; wavelets; doshärmning;

    Sammanfattning : Treating cancer with radiotherapy requires precise planning. Several planning pipelines rely on reference dose mimicking, where one tries to find machine parameters best mimicking a given reference dose. Dose mimicking relies on having a function that quantifies dose similarity well, necessitating methods for feature extraction of dose images. LÄS MER

  5. 24. Semantic segmentation using convolutional neural networks to facilitate motion tracking of feet : For real-time analysis of perioperative microcirculation images in patients with critical limb thretening ischemia

    Master-uppsats, Linköpings universitet/Avdelningen för medicinsk teknik

    Författare :Andreas Öberg; Martin Hulterström; [2021]
    Nyckelord :semantic segmentation; convolutional neural network; critical limb threatening ischemia; ROI tracking; deep learning;

    Sammanfattning : This thesis investigates the use of Convolutional Neural Networks (CNNs) toperform semantic segmentation of feet during endovascular surgery in patientswith Critical Limb Threatening Ischemia (CLTI). It is currently being investigatedwhether objective assessment of perfusion can aid surgeons during endovascularsurgery. LÄS MER

  7. 25. Variable selection for generalized linear mixed model by L1 penalization for predicting clinical parameters of ovarian cancer

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Lan Hoa Diep; [2021]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : The quantity of biomarkers, which are proteins in this case, in ovarian cancer (OC) tumor and immune tissue regions of interest (ROIs) were measured with the new technology Digital Spatial Profiler (DSP). These measurements were used to construct regression models on the biomarkers to predict for two clinical parameters; tumor type (”Type 1” vs ”Type 2”) and the immune infiltration type (”Cavities” vs ”Dispersed”).
