Mechanisms affecting ALARA MI selected in adaptive ultrasound imaging

Conference IEEE International Ultrasonics Symposium Ius · January 1, 2021 Adaptive acoustic output selection in ultrasound imaging promises to improve adherence to the ALARA (as low as reasonably achievable) principle. Demonstrated imaging sequences have balanced image quality and safety considerations based on transducer channe ... Full text Cite

Implementation and Clinical Evaluation of a Fetal ALARA Ultrasound System

Conference IEEE International Ultrasonics Symposium Ius · December 17, 2018 The US Food and Drug Administration (FDA) provides guidelines for acoustic output to ensure that ultrasound remains a safe imaging modality used widely in applications such as obstetrics. However, even within these limits, additional acoustic output that d ... Full text Cite

Notice of Removal: Translation of fetal short-lag spatial coherence (SLSC) imaging into clinical practice: A pilot study

Conference IEEE International Ultrasonics Symposium Ius · October 31, 2017 Fetal short-lag spatial coherence (SLSC) imaging has demonstrated 64-85% increases in CNR and 17-29% increases in contrast relative to conventional B-mode imaging. However, despite its proven technical efficacy, the viability of fetal SLSC in the clinical ... Full text Cite
