  1. 16. Uncertainties in the use of synthetic CT (sCT) for daily online adaptive radiotherapy for lung cancer

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Johansson Vivika; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Background and purpose: Cone Beam Computed Tomography (CBCT) based online adaptive radiotherapy (oART) has been clinically implemented for several anatomical sites worldwide. However, random and abrupt anatomical changes with large density alterations can occur in lung patients, leading to uncertainties with synthetic computed tomography (sCT) and dose calculation.

  3. 17. Predictive MR Image Generation for Alzheimer’s Disease and Normal Aging Using Diffeomorphic Registration

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

    Author : Yuqi Zheng; [2023]
    Keywords : Medical Image Generation; Brain Aging; Diffeomorphic Registration; AlzheimerŠs Disease; Medicinsk bildgenerering; Åldrande av hjärnan; DiffeomorĄsk registrering; Alzheimers sjukdom;

    Abstract : Alzheimer´s Disease (AD) is the most prevalent cause of dementia, signifying a progressive and degenerative brain disorder that causes cognitive function deterioration including memory loss, communication difficulties, impaired judgment, and changes in behavior and personality. Compared to normal aging, AD introduces more profound cognitive impairments and brain morphology changes. READ MORE

  4. 18. Dystoki hos sto : 138 fall vid tre djursjukhus i Sverige (2006-2022)

    University essay from SLU/Dept. of Clinical Sciences

    Author : Elin Olsson; [2023]
    Keywords : dystoki; häst; sto; föl; förlossning; kejsarsnitt;

    Abstract : Dystokin hos hästen beskrivs ofta i litteraturen som ”a true emergency”. Få andra akutfall, om några, är så akuta i hästpraktiken. För fölet handlar det om liv eller död – de häftiga kontraktionerna hos stoet gör att syrebrist hos fölet uppstår snabbt. READ MORE

  5. 19. Region-based analysis of magnetic resonance brain images: integrating statistical analysis and visualization

    University essay from

    Author : Yu-Ping Hsu; [2022-04-05]
    Keywords : Medical physics; Neuroimage; Brain segmentation; Statistical analysis; Visualization;

    Abstract : Purpose: The purpose of the project was to develop a processing toolchain that takes MR brain images and their anatomical segmentations as input and produces image visualizations, data visualizations, and statistical analyses in a unified manner for the users who work with neuroimaging and quantitative brain anatomy, including pathological anatomy. A secondary aim was to package and release the software publicly as open source. READ MORE

  6. 20. Effects of reconstruction parameters on the image quality and quantification of PET images from PET/MRI and PET/CT systems

    University essay from

    Author : Ali Amena Hussain; [2022-03-09]
    Keywords : Medical physics; PET CT; PET MRI; OSEM; BPL; NEMA IQ; positron emission tomography; magnetic resonance imaging; computed tomography; ordered Subset Expectation Maximization; The Bayesian Penalized Likelihood;

    Abstract : Aim: To study how reconstruction parameters affect the positron emission tomography (PET) image quality and quantitative results for the different lesion to background radioactivity ratios in three different PET systems. Introduction: Multimodality imaging that combines magnetic resonance imaging (MRI) or computed tomography (CT) with a PET system can produce medical images containing both functional and anatomical information.
