  1. 1. Image-driven simulation of brain tumors using a reaction-diffusion mathematical model

    University essay from Linköpings universitet/Avdelningen för medicinsk teknik

    Author : Kristos Qiqi; [2023]
    Keywords : brain tumor; cancer; mathematical model; simulation; magnetic resonance images; hjärntumör; cancer; matematisk model; simulering; magnetresonanstomografi bilder;

    Abstract : Brain tumors pose a big challenge in the field of neuro-oncology. Gliomas are the largest subgroup. Magnetic resonance imaging is a non-invasive tool for detecting and characterizing these tumors. Mathematical models, such as the reaction-diffusion equation, can be used for understanding the intricate behavior of gliomas. READ MORE

  3. 2. Domain Adaptation for Multi-Contrast Image Segmentation in Cardiac Magnetic Resonance Imaging

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Thomas Proudhon; [2023]
    Keywords : Cardiac Magnetic Resonance Imaging; Deep Learning; Domain Adaptation; Unsupervised Segmentation; Image-to-image Translation;

    Abstract : Accurate segmentation of the ventricles and myocardium on Cardiac Magnetic Resonance (CMR) images is crucial to assess the functioning of the heart or to diagnose patients suffering from myocardial infarction. However, the domain shift existing between the multiple sequences of CMR data prevents a deep learning model trained on a specific contrast to be used on a different sequence. READ MORE

  4. 3. Comparison of In Vivo Intramuscular Fat Quantification Techniques in MRI

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Pien Derikx; [2023]
    Keywords : Fat-water separation; Dixon technique; Intramuscular fat quantification;

    Abstract : People with cerebral palsy (CP) may develop muscle contractures, which are defined as a loss of joint range due to an increase in passive muscle stiffness [1]. Computer models suggest that intramuscular fat can increase muscle stiffness [2]. READ MORE

  5. 4. Exploring persistent homology as a method for capturing functional connectivity differences in Parkinson’s Disease.

    University essay from KTH/Matematik (Avd.)

    Author : Naomi Hulst; [2022]
    Keywords : persistent homology; topological data analysis; computational topology; parkinson s disease; parkinson; functional connectivity; stable rank; ihållande homologi; topologisk data analys; beräknings topologi; Parkinsons sjukdom; parkinson; funktionell konnektivitet; stable ranks;

    Abstract : Parkinson’s Disease (PD) is the fastest growing neurodegenerative disease, currently affecting two to three percent of the population over 65. Studying functional connectivity (FC) in PD patients may provide new insights into how the disease alters brain organization in different subjects. READ MORE

  6. 5. The brain in conversation: Mapping the neural correlates of turn-taking, production, and comprehension using fMRI

    University essay from Stockholms universitet/Institutionen för lingvistik

    Author : Caroline Arvidsson; [2022]
    Keywords : turn-taking; production; comprehension; conversation; fMRI; speech planning; turtagning; produktion; förståelse; konversation; fMRI; språkplanering;

    Abstract : Conversation is the primary mode of language use. A key feature of conversation is turn-taking, during which interlocutors rapidly switch between speaker and listener roles without conscious effort. READ MORE
