1. Semi-Automatic Analysis and Visualization of Cardiac 4D Flow CT
University essay from Linköpings universitet/Institutionen för hälsa, medicin och vårdAbstract : The data obtained from computational fluid dynamics (CFD) simulations of blood flow in the heart is plentiful, and processing this data takes time and the procedure for that is not straightforward. This project aims to develop a tool that can semi-automatically process CFD simulation data, which is based on 4D flow computed tomography (CT) data, with minimal user input. READ MORE

2. Exploring Deep Learning Frameworks for Multiclass Segmentation of 4D Cardiac Computed Tomography
University essay from Linköpings universitet/Institutionen för hälsa, medicin och vårdAbstract : By combining computed tomography data with computational fluid dynamics, the cardiac hemodynamics of a patient can be assessed for diagnosis and treatment of cardiac disease. The advantage of computed tomography over other medical imaging modalities is its capability of producing detailed high resolution images containing geometric measurements relevant to the simulation of cardiac blood flow.

3. Movement tracking of the carotid artery with 4D ultrasound imaging
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : The leading cause of death in the world is cardiovascular diseases. Scientific discoveries have been made that correlate the movement of the arterial walls and blood flow patterns with cardiovascular diseases. These movements have been studied with ultrasound 2D imaging. READ MORE

4. A comparative treatment planning study of radiotherapy of clinical liver- and stomach-cancer cases with either photon or proton beams
University essay from Stockholms universitet/FysikumAbstract : There has been an increasing interest in proton beam therapy (PBT) in recent years related to the advantageous depth-dose characteristics of proton beams compared to what is achievable with standard external photon beam radiotherapy (RT). With PBT, improved target dose conformity can be achieved together with a reduction in the dose to the organs at risk (OARs). READ MORE
