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.

A paper co-authored by Professor Kevin Parker titled "Spatial Angular Compounding Technique for H-scan Ultrasound Imaging" will appear in the January 2018 issue of Ultrasound in Medicine and Biology and can be found here. The paper is a collaboration with Drs. Mawia Khairalseed (first author), Fangyuan Xiong, Jung-Whan Kim, Robert Mattrey, and Kenneth Hoyt at UT-Dallas/UT Southwestern Medical Center. The article describes the implementation of H-scan using plane wave imaging and the investigation of the impact of spatial angular compounding on H-scan image quality.
