A Phantom-Based Assessment of Repeatability and Reproducibility of Transvaginal Quantitative Ultrasound

This article evaluated the repeatability and reproducibility (RR logBSC: 0.50–0.68 dB), indicating high measurement precision. These values are small compared to the ranges of AC (0.28–0.99 dB/cm-MHz) and logBSC (−33.16 to −20.35 dB) of the five phantoms. The AC and logBSC biomarkers measured on transvaginal QUS phantoms using the reference phantom method are repeatable, and reproducible between sonographers, transducers, and probe...
