Abstract
A cervical probe, equipped with both a tactile sensor array and an ultrasound transducer array, is engineered for the simultaneous acquisition of stress and ultrasound strain data from cervical sectors, as well as for the measurement of cervical length. The collected stress and strain data from various cervical sectors are transmitted to a data processor. This processor calculates cervical elasticity using a strain-to-stress ratio. Subsequently, the arithmetic mean of the stress-to-strain ratios is compared with a predetermined cutoff value, and the measured cervical length is evaluated against another predetermined value, to predict preterm birth during gestational weeks 24-28.
