Dose Estimation by Geant4-Based Simulations for Cone-Beam CT Applications: A Systematic Review

The last two decades have witnessed increasing use of X-ray imaging and, hence, the exposure humans to potentially harmful ionizing radiation. Computed tomography accounts for largest portion medically-related exposure. Accurate knowledge radiation dose from Cone-Beam CT (CBCT) is great importance estimate risks and justification exposures. This work aimed review published evidence on CBCT estimation by focusing studies that employ Geant4-based toolkits dosage. A systematic based a scientometrics approach was conducted retrospectively, January 2021, comprehensive overview trend, thematic focus, scientific production in this topic. search using WOS, PubMed, Scopus databases, according Preferred Reporting Items Systematic Reviews Meta-Analyses (PRISMA) statement. In total, 93 unique papers were found, which only 34 met inclusion criteria. We opine findings study provides basis develop accurate simulations equipment optimizing trade-off between clinical benefit risk.
