  1. 1. Texture Analysis and Ultra high-frequency ultrasound in use for diagnosing Hirschsprung's disease

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Sophia Klarén; Jonathan Jedhammar; [2023]
    Nyckelord :Hirschsprung s disease; Aganglionosis; UHF ultrasound; Texture analysis; Nakagami; Skewness; Kurtosis; Technology and Engineering;

    Sammanfattning : An investigation into the use of statistical texture analysis in combination with ultra high-frequency ultrasound for diagnosing Hirschsprung’s disease (HD); An illness that manifests itself through the absence of ganglia cells in lower parts of the intestine. Current diagnostic techniques carry a higher risk of long-term consequences in newborns and children which enables a new avenue of research into new methods. LÄS MER
