  1. 1. Clinical outcomes after using of Rhythmia mapping system in patients with differentcomplex arrhythmias

    Master-uppsats, Örebro universitet/Institutionen för medicinska vetenskaper

    Författare :Hanna Ibrahim; [2021]
    Nyckelord :Cardiac arrhythmias; Radiofrequency ablation; Rhythmia mapping system; Electro-anatomical cardiac maps; Ablations outcomes.;

    Sammanfattning : Background: Rhythmia is a novel mapping system of cardiac arrhythmias, it utilizes a multielectrode catheter, Orion. Together these two instruments generate high accurate maps of the cardiac chamber which facilitate the identification of arrythmia focus and its ablation. LÄS MER

  3. 2. Diffuse correlation spectroscopy for estimation of coagulation thickness : a phantom study

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Zeyneb Alsadi; [2019]
    Nyckelord :DCS; Diffuse correlation spectroscopy; Biomedical optics; coagulation; phantom study; coagulation depth; coagulation thickness; diffusion; model; two layer model;

    Sammanfattning : The objective of this preliminary study was to determine the potential of diffuse correlation spectroscopy (DCS) for assessment of coagulation depth. Coagulation of tissue can occur due to a number of different reasons such as thermal or electrical burns or radiofrequency ablation. LÄS MER

  4. 3. Simulation of radio-frequency ablation of liver tumors : Development of a power regulation model and comparison with microwave ablation

    Magister-uppsats, Mekanisk värmeteori och strömningslära

    Författare :Chiara Sammartano; [2011]
    Nyckelord :;

    Sammanfattning : Local therapy with radiofrequency ablation (RFA) is an important method for treating liver tumors mostly in early stage, which has been increasingly used in recent years. RFA utilizes an RF current that is applied to the target tissue through an electrode connected with a power generator and percutaneously inserted into the tumor; the electrode power causes the tissue temperature rise required for destroying cancer cells.
