Bibliometric Analysis of Diffuse Optical Tomography Studies Between 1994-2024
Abstract
This study covers the period 1994–2024 of bibliographic research on Diffuse Optical Tomography (DOT), using data retrieved from the Web of Science (WOS) database. The primary objective is to conduct a comprehensive bibliometric analysis of academic publications on DOT by constructing networks of authorship, sources, citations, keywords, institutions, and countries. The analysis was performed using the "Bibliometrix" package in R, supplemented by descriptive statistical methods. Over the past 30 years, the study identified key publication trends, evolving research priorities, and emerging thematic areas within the field. A total of 759 scientific documents published across 293 different sources were analyzed. The author collaboration network revealed an average of 5.39 co-authors per publication, and approximately 26% of the studies involved international collaboration. The most productive authors contributed up to 50 or more publications, while over 65% of the contributors authored only a single article. These findings highlight both concentrated research efforts by leading scholars and a wide distribution of interest among broader scientific communities.
