Objective Estimates of ultrasonic attenuation (the loss of energy as an ultrasonic wave
propagates through tissue) have been used to evaluate the structure and function of tissues …

Attenuation estimation and imaging in the cervix has been utilized to evaluate the onset of
cervical ripening during pregnancy. This feature has also been utilized for the acoustic …

The purpose of this study was to determine whether cervical ultrasonic attenuation could
identify women at risk of spontaneous preterm birth. During pregnancy, women (n= 67) …

Premature delivery is the leading cause of infant mortality in the United States. Currently,
premature delivery cannot be prevented and new treatments are difficult to develop due to …

Attenuation coefficient estimation has the potential to be a useful tool for placental tissue
characterization. A current challenge is the presence of inhomogeneities in biological tissue …

The objective of this study was to determine whether estimates of ultrasonic attenuation
could detect changes in the cervix associated with medically induced cervical remodeling …

To effectively postpone preterm birth, cervical ripening needs to be detected and delayed.
As the cervix ripens, the spacing between the collagen fibers increases and fills with water …

Objective: The purpose of the current study was to determine in vivo, tissue-specific
ultrasonic attenuation coefficients for each of the tissue layers comprising the anterior …

A specialized in vivo exposimetry system was developed to acquire transabdominal in situ
ultrasound exposure quantities in obstetric patients. Under surgical conditions, the sterilized …

As pregnancy progresses, the cervix remodels from a rigid structure to one pliable enough to
allow delivery of a fetus, a process that involves progressive disorganization of cervical …
