H-scan Analysis of Thyroid Lesions

A paper co-authored by Professor Kevin Parker and MD/PhD student Gary Ge titled "H-scan analysis of thyroid lesions" will appear in the January-March 2018 issue of the Journal of Medical Imaging and can be found here. The paper is a collaboration with Professor Roberto Lavarello of the Pontificia Universidad Catolica del Peru (Lima, Peru), and Drs. Joseph Pinto, Rosa Laimas, Jorge Guerrero, Himelda Chavez, and Claudia Salazar of Oncosalud (Lima, Peru). The article describes the application of the H-scan framework in a preliminary study of thyroid lesions to examine the H-scan outputs for three categories: normal thyroid, benign lesions, and cancerous lesions within a total group size of 46 patients. In addition, phantoms comprised of spherical scatterers are analyzed to establish independent reference values for comparison. The results demonstrate a small but significant difference in some measures of the H-scan channel outputs between the different groups.
