Abstract
Methods and system are described for multi-modal, multi-parametric, non-invasive, and real-time assessment of cervical tissue through a multi-modal probe device for use within a vaginal canal and an associated imaging system to assess a risk of preterm delivery of an expectant mother. The multi-modal system may include ultrasound (US) imaging, viscoelastic (VE) imaging, and/or photoacoustic (PA) imaging of the cervical issue to determine cervical biomarker information indicative of parameters including, but not limited to, a collagen to water ratio such that a more water dominant ratio is indicative of a risk of preterm delivery.
