  1. 1. Model for Process Time Analysis in Magnetic Resonance Imaging : Workflow Optimization to Reduce Access Time

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Elina Broman; [2020]
    Keywords : MRI; market research Sweden; efficiency; access time; MRT; marknadsundersökning Sverige; effektivitet; väntetider;

    Abstract : Magnetic Resonance Imaging (MRI) can be used in many clinical situations, but they are limited by high costs and time-consuming properties. Most focus has been on improving the technical side of MRI, and not as much on process improvements. READ MORE

  3. 2. Differences in tumor volume for treated glioblastoma patients examined with 18F-fluorothymidine PET and contrast-enhanced MRI

    University essay from Umeå universitet/Institutionen för fysik

    Author : Karolina Hedman; [2020]
    Keywords : PET MRI; positron emission tomography; magnetic resonance imaging; brain tumor; glioblastoma; image segmentation; adaptive thresholding; feature extraction; radiotracer; gadolinium; image processing; image analysis;

    Abstract : Background: Glioblastoma (GBM) is the most common and malignant primary brain tumor. It is a rapidly progressing tumor that infiltrates the adjacent healthy brain tissue and is difficult to treat. Despite modern treatment including surgical resection followed by radiochemotherapy and adjuvant chemotherapy, the outcome remains poor. READ MORE

  4. 3. AI-based Age Estimation from Mammograms

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap; Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Dilukshi Charitha Subashini Dissanayake Dissanayake Lekamlage; Fabia Afzal; [2020]
    Keywords : Machine Learning; Mammograms; Image Segmentation; Deep Learning; Feature Extraction; Regression Analysis; Age Estimation;

    Abstract : Background: Age estimation has attracted attention because of its various clinical and medical applications. There are many studies on human age estimation from biomedical images such as X-ray images, MRI, facial images, dental images etc. However, there is no research done on mammograms for age estimation.

  5. 4. Implementation and verification of a quantitative MRI method for creating and evaluating synthetic MR images

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Aleksander Blagoiev; [2020]
    Keywords : MRI; Quantitative MRI; Synthetic MRI;

    Abstract : The purpose of this thesis was to implement and quantitatively test a quantitative MRI (qMRI) method, from which synthetic MR images are created and also evaluated. The parameter maps of T1, T2*, and effective proton density (PD*) were tested with reference tubes containing different relaxation times, and concentrations of water (H2O) and heavy water (D2O).

  6. 5. Evaluation of two CNN models, VGGNet-16 & VGGNet-19, for classification of Alzheimer’s disease in brain MRI scans

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

    Author : Tim Jonsson; Isabella Tapper; [2020]
    Keywords : ;

    Abstract : Computer-aided-diagnosis (CAD) emerged in the early 1950s and since then CAD has facilitated the diagnosing of many medical conditions and diseases. In particular, CADfor Alzheimer’s disease (AD) has been immensely researched the last decade thanks to advanced neuroimaging techniques such as magnetic resonance imaging (MRI) and positron emission tomography (PET).
