To train ultrasound technologists (equivalently called sonographers) in remote ultrasound guidance.

To capture imaging of the gynecologic organs visible on home ultrasound and pertinent to clinical care, specifically the ovaries and uterus.

To train the independent readers, both obstetricians & gynecologists (OB/GYNs) and reproductive endocrinologists (REIs), who will evaluate home ultrasound images over time in subsequent clinical trials.
