  1. 1. Quantification of Fetal Volume in Magnetic Resonance Images Using Deep Learning

    University essay from Lunds universitet/Matematik LTH

    Author : Amanda Nilsson; [2021]
    Keywords : MRI; Deep Learning; U-Net; Semantic segmentation; Fetal body volume; fetal MRI; Segmentation; Magnetic Resonance Imaging; Mathematics and Statistics;

    Abstract : Background: Fetal Magnetic Resonance Imaging is an imaging technique that visualizes the fetus during pregnancy. It is used for assessing and diagnosing disease, for monitoring high risk pregnancies, and for conducting research. READ MORE

  3. 2. Image Distance Learning for Probabilistic Dose–Volume Histogram and Spatial Dose Prediction in Radiation Therapy Treatment Planning

    University essay from KTH/Matematisk statistik

    Author : Ivar Eriksson; [2020]
    Keywords : Radiation therapy; automated planning; machine learning; autoencoder; distance optimisation; sparse pseudo-input Gaussian process; kernel density estimation; dose mimicking; dose–volume histogram; Strålbehandling; automatiserad dosplanering; maskininlärning; autoencoder; distansoptimering; glesa Gaussiska processer; sannolikhets-fördelnings-estimering; dosrekonstruktion; dos–volymhistogram;

    Abstract : Construction of radiotherapy treatments for cancer is a laborious and time consuming task. At the same time, when presented with a treatment plan, an oncologist can quickly judge whether or not it is suitable. This means that the problem of constructing these treatment plans is well suited for automation. READ MORE

  4. 3. Beräkning av bendensitet och benvolym vid datortomografisk helkroppsundersökning av katt : jämförelse av två metoder för beräkning samt inverkan av storlek, ålder, kön och osteoartrit

    University essay from SLU/Dept. of Clinical Sciences

    Author : Stefan Lindén; [2020]
    Keywords : katt; bendensitet; benvolym; datortomografi; benvolym; ålder; kön; storlek; felin osteoartrit;

    Abstract : Bone volume and bone density may be affected by disease. Measurement of bone volume and bone density in cats could possibly be used as a tool in diagnosing osteoarthritis (OA), lameness and other diseases expected to affect bone density and bone volume. Measurement of bone volume is also useful when evaluating body composition. READ MORE

  5. 4. Automatic Volume Estimation Using Structure-from-Motion Fused with a Cellphone's Inertial Sensors

    University essay from Linköpings universitet/Datorseende

    Author : Marcus Fallqvist; [2017]
    Keywords : Computer vision; Volume Estimation; Structure-from-motion; Space Carving; 3D Reconstruction; Point Cloud; OpenCV; OpenMVG; Senor Fusion; Scale Estimate; Video; Tracking; IMU; Camera;

    Abstract : The thesis work evaluates a method to estimate the volume of stone and gravelpiles using only a cellphone to collect video and sensor data from the gyroscopesand accelerometers. The project is commissioned by Escenda Engineering withthe motivation to replace more complex and resource demanding systems with acheaper and easy to use handheld device. READ MORE

  6. 5. Ray Cast/Dose Superposition algorithm for proton grid therapy

    University essay from Stockholms universitet/Medicinsk strålningsfysik (tills m KI)

    Author : Tibor Marusic; [2017]
    Keywords : Proton Grid Therapy Treatment Radiation Dose Distribution Superpositioning Interlace Planning System Volume Effect Ray Cast Algorithm Medical Trace Plan Program Python Computer Tomography Volume Of Interest;

    Abstract : Purpose: To develop a Ray Cast/Dose Superposition (RC/DS) algorithm for proton grid therapy. Its functionality needed to include automatic positioning of small proton pencil beams in a grid-pattern and superimposing thin beam Monte Carlo (MC) dose distribution data on a Computer Tomography (CT) density volume.
