  1. 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)

    Author : Edoardo Realini; [2023]
    Keywords : Data management; medical imaging; label nomenclature; deep learning; radiology; Datahantering; medicinsk avbildning; etikettnomenklatur; djupinlärning; radiologi;

    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

  3. 2. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Jules Reniaud; [2022]
    Keywords : Technology and Engineering;

    Abstract : 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

  4. 3. Feasibility of Dynamic SPECT-Renography with Automated Evaluation Using a Deep Neural Network

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Viktor Rogowski; [2021]
    Keywords : Medicine and Health Sciences;

    Abstract : 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

  5. 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 radiologi

    Author : Amanda Eriksson; [2021]
    Keywords : Cerebral Blood Flow; CBF; oxygen-15-labelled water; PET CT; PET MR; Quantification of CBF; Image Derived Input Function; IDIF; Blood Sampled Input Function; BSIF; Arterial Input Function; AIF; Tracer Kinetic Modelling; Single Tissue Compartmental Model; 1TCM;

    Abstract : 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

  6. 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)

    Author : David Dashti; [2021]
    Keywords : Healthcare Informatics; Quality Assurance; Process Modelling; Radiology; Multi-actor System Analysis; System Analysis; Hälsoinformatik; Kvalitetsledning; Processmodellering; System Analys; Radiologi; Multi-aktör System Analys;

    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
