  1. 1. 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

  3. 2. Automatic Left Ventricle Segmentation of Long-Axis Cardiac MRI-Images

    University essay from Lunds universitet/Matematik LTH

    Author : Ruben Bergengrip; [2021]
    Keywords : MRI; Magnetic resonance imaging; Deep Learning; Machine learning; U-net; CNN; Semantic segmentation; Segmentation; Global longitudinal strain; GLS; strain; AV-plane displacement; AVPD; long-axis; left ventricle; LV; cardiac MRI; CMR; Image analysis; Technology and Engineering;

    Abstract : Over 30 % of all deaths worldwide are related to cardiovascular diseases and they are the leading cause of death. Therefore, research into treatment, diagnosis and prognostication of these diseases are of critical importance. One way to examine the cardiovascular system is through the use of Magnetic Resonance Imaging (MRI). READ MORE

  4. 3. AUTOMATED IDENTIFICATION OF CALCIUM IN MITRAL AND AORTIC VALVES

    University essay from Lunds universitet/Matematik LTH

    Author : Lisa Wikman; [2020]
    Keywords : Technology and Engineering;

    Abstract : Calcification of the mitral and aortic valves is one of the main precursors to heart valve diseases. Calcified valves and coronary vessels is also an indication of risk for future cardiac events such as cardiac infarct(1)(2). READ MORE

  5. 4. Image analysis tool for geometric variations of the jugular veins in ultrasonic sequences : Development and evaluation

    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : Arvid Westlund; [2018]
    Keywords : active contour; ultra sound; ultrasonic; image analysis; internal jugular veins; snake;

    Abstract : The aim of this project is to develop and perform a first evaluation of a software, based on the active contour, which automatically computes the cross-section area of the internal jugular veins through a sequence of 90 ultrasound images. The software is intended to be useful in future research in the field of intra cranial pressure and its associated diseases. READ MORE

  6. 5. Deep Learning Algorithms for Cardiac Image Classification and Landmark Detection

    University essay from Lunds universitet/Matematik LTH
