1. 1. Robustness Analysis of Perfusion Parameter Calculations

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

   Author : Alicia Palmér; [2024]
   Keywords : Perfusion; Medical image analysis; Dynamic Contrast Enhanced Magnetic Resonance Imaging; Tofts model; Functional imaging; Optimization; T1 map; Perfusion; Medicinsk bildanalys; Dynamisk kontrastförstärkt magnetisk resonanstomografibildtagning; Tofts-modell; Funktionell bildbehandling; Optimering; T1 karta;

   Abstract : Cancer is one of the most common causes of death worldwide. When given optimal treatment, however, the risk of severe illness may greatly be reduced. Determining optimal treatment in turn requires evaluation of disease progression and response to potential, previous treatment. READ MORE

3. 2. Monte Carlo evaluation of static and dynamic 6FFF treatments - Evaluation of dose distributions calculated with AAA, Acuros XB, and Collapsed Cone (RayStation and DoseCheck)

   University essay from

   Author : Alma Blombäck; [2023-02-23]
   Keywords : Medical physics; Monte Carlo; 6FFF; AAA; Acuros XB; DoseCheck; RayStation; DVH evaluation; flattening filter free;

   Abstract : There are several benefits to removing the standard flattening filter and using so-called flattening filter free (FFF) treatments in external radiation therapy with photons. The main advantage is the possibility of significantly shortening the treatment time, de spite this FFF is not widely used yet. READ MORE

4. 3. Synthesizing of brain MRE wave data

   University essay from KTH/Medicinsk avbildning

   Author : Maryia Yuliuhina; [2023]
   Keywords : MR elastography; brain MRE; synthetic data; computational modeling; shear wave elastography; MR-elastografi; hjärn MRE; syntetiska data; beräkningsmodellering; skjuvvåg elastografi;

   Abstract : Magnetic resonance elastography (MRE) is an imaging technique that allows for non-invasive access to the physical properties of body tissues. MRE has great potential, but it is difficult to conduct research due to the time-consuming estimation of stiffness maps, which could be speeded up by using neural network. READ MORE

5. 4. Evaluation of deep learning image reconstruction for brain- and abdominal CT - A visual grading characteristics study

   University essay from

   Author : Tuva Skarp; [2022-05-04]
   Keywords : Medical physics; CT; Computed tomography; imaging; Deep learning image reconstruction;

   Abstract : Computed tomography (CT) is a common medical imaging method today. There are different ways of reconstructing the images from a CT examination. The standard method is the filtered back projection (FBP). READ MORE

6. 5. Diffusion-Based MR Methods for Measuring Water Exchange

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : Shan Cai; [2022]
   Keywords : diffusion MRI; water exchange rate; membrane permeability; double diffusion encoding; DDE;

   Abstract : Measuring transmembrane water exchange can provide potential biomarkers for tumors and brain disorders. Diffusion Magnetic Resonance Imaging (dMRI) is a well-established tool that can non-invasively measure water exchange across cell membranes. Diffusion Exchange Spectroscopy (DEXSY) is one of the dMRI-based frameworks used to estimate exchange. READ MORE
