1. A novel nomenclature for the identification of ground truth in medical imaging data : Design, implementation and integration in a large knowledge database
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The annotation of medical images is a critical task for many downstream applications. However, the lack of a unified annotation nomenclature has resulted in inconsistency and ambiguity in the storage and use of such data. In this thesis, we propose and evaluate a novel annotation nomenclature for medical images. READ MORE

2. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. READ MORE

3. Feasibility of Dynamic SPECT-Renography with Automated Evaluation Using a Deep Neural Network
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Introduction: Renography is a standard diagnostic examination that evaluates renal function, renal pelvic dilatation and urinary obstruction. Renography is performed by injecting a radiopharmaceutical (predominately 99mTc-MAG3) and using gamma camera to image the biodistribution in a dynamic sequence. READ MORE

4. Quantification of cerebral blood flow with 15O-water PET : A comparison study between PET/CT and PET/MR and two different blood sampling instruments
University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Diagnostisk radiologiAbstract : Cerebral blood flow quantification is a vital diagnostic tool for disease monitoring and used for diagnosing a variation of pathological conditions. The human brain requires roughly about 20 % of the total cardiac output to sustain normal functioning, hence the perfusion of blood is an important factor to deliver oxygenated blood. READ MORE

5. Improving Quality Assurance of Radiology Equipment Using Process Modelling and Multi-actor System Analysis
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : With the introduction of RIS and PACS technologies in clinical radiology, the field has become increasingly technology dependent. The quality assurance in radiology have however yet to catch on. With many quality assurance programs mainly focusing on the clinical side of radiology whilst little attention is paid to the technical aspects. READ MORE
