  1. 1. Optimization-Based Geometry Correction Of Blood Flow CFD Simulations Using 4D-Flow Data

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fritiof Hegardt; [2022]
    Keywords : Technology and Engineering;

    Abstract : 4D-flow is a powerful tool capable of capturing 3-dimensional, time-resolved flow measurements of blood flow in the body. Their current use is limited by resolution and scan times. A proposed solution is to use Simulation Based Imaging (SBI). READ MORE

  3. 2. Real-time characterization of fuel by Near-Infrared spectroscopy : Quantitative measurements of moisture content, ash content, heating value, and elemental compositions in solid biofuel mixtures

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Kajsa Edlund; Ali Ahmad Shahnawazi; [2021]
    Keywords : NIR; spectroscopy; solid biofuel mixtures; moisture content; ash content; heating value; elemental composition; boiler; CHP pant; CCS; CO2; emissions; NIR; spektroskopi; fasta biobränsleblandningar; fukthalt; ask innehåll; värmevärde; elementär komposition; panna; kraftvärmeverk; CCS; CO2; utsläpp;

    Abstract : The global energy demand supplies mainly from fossil fuels, which is neither sustainable nor environmentally friendly and aims to global warming. Therefore, both more investments in renewable energy sources such as bioenergy are required, as well as new technologies such as carbon capture and storage (CCS) to handle the emissions from existing combined heat and power (CHP) plants.

  4. 3. Machine Learning for LiDAR-SLAM : In Forest Terrains

    University essay from Linköpings universitet/Datorseende

    Author : Anton Hjert; [2021]
    Keywords : SLAM; Point set registration; Scan correction; Simultaneous localization and mapping; AdaBound;

    Abstract : Point set registration is a well-researched yet still not a very exploited area in computer vision. As the field of machine learning grows, the possibilities of application expand. READ MORE

  5. 4. Coil Sensitivity Estimation and Intensity Normalisation for Magnetic Resonance Imaging

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Rebecka Herterich; Anna Sumarokova; [2019]
    Keywords : Image reconstruction; Magnetic Resonance Imaging; sensitivity encoding; Parallell imaging; Coil sensitivity; ISMRM raw data; Magnetresonanstomografi; känslighetskodning; bildrekonstruktion; Parallell imaging; Spolkänslighet; ISMRMRD;

    Abstract : The quest for improved efficiency in magnetic resonance imaging has motivated the development of strategies like parallel imaging where arrays of multiple receiver coils are operated simultaneously in parallel. The objective of this project was to find an estimation of phased-array coil sensitivity profiles of magnetic resonance images of the human body. READ MORE

  6. 5. Dosimetric verification of synthetic CT using Cone Beam CT in an MRI only workflow

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Emilia Palmér; [2017]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and purpose: The MRI only workflow aims to base the treatment planning solely on magnetic resonance imaging (MRI), hence excluding the traditional computed tomography (CT) scan. To do that synthetic computed tomography (sCT) data is generated, replacing the conventional CT data. READ MORE
