1. 16. Image Processing in MRI Guided Real-TimeAdaptive Radiotheraphy - Upsampling and Segmentation of Target Volume and Organs at Risk

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Shreyas Shivakumara; [2021]
   Keywords : ;

   Abstract : Magnetic Resonance Imaging (MRI) is a useful medical imaging technique that is used for cancer treatment.The major drawback of this method is the relatively long scan time, limiting its use for real time tracking of a potentially moving target during the radiotherapy session.

3. 17. Automatic magnetic resonance brain volume measurements to assess the effect of minimised blood sample extraction on brain development in extremely preterm infants

   University essay from Lunds universitet/Läkarutbildningen

   Author : Hickmat Hamie; [2021]
   Keywords : Magnetic resonance imaging; Brain development; Prematurity; Medicine and Health Sciences;

   Abstract : Aim: To evaluate a pipeline for automatic MRI brain segmentation and volumetric tissue structure quantification in a cohort of extremely preterm infants. Methods: 13 extremely preterm neonates underwent MRI-scanning at a term equivalent age. Seven of these subjects had suitable MRI sequences and were analyzed in the pipeline. READ MORE

4. 18. Improving Brain Tumor Segmentation using synthetic images from GANs

   University essay from Linköpings universitet/Statistik och maskininlärning

   Author : Aashana Nijhawan; [2021]
   Keywords : Image segmentation; Generative Adversarial Networks; GANs; Computer Vision; synthetic images; generator; discriminator; uncertainty estimation; deep neural networks; U-net; PGGAN;

   Abstract : Artificial intelligence (AI) has been seeing a great amount of hype around it for a few years but more so now in the field of diagnostic medical imaging. AI-based diagnoses have shown improvements in detecting the smallest abnormalities present in tumors and lesions. This can tremendously help public healthcare. READ MORE

5. 19. GAN-Based Synthesis of Brain Tumor Segmentation Data : Augmenting a dataset by generating artificial images

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : Mehdi Foroozandeh; [2020]
   Keywords : generative adversarial networks; deep learning; machine learning; image segmentation; image synthesis; image processing; computer vision; medical imaging; medical image segmentation; medical image processing;

   Abstract : Machine learning applications within medical imaging often suffer from a lack of data, as a consequence of restrictions that hinder the free distribution of patient information. In this project, GANs (generative adversarial networks) are used to generate data synthetically, in an effort to circumvent this issue. READ MORE

6. 20. 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
