The handheld ultrasound developer designed Clarius OB AI to improve access to obstetrical prenatal monitoring and care in resource-limited areas. It can automatically perform fetal biometry measurements to estimate fetal age, weight and growth intervals.
Clarius OB AI was developed with deep learning models that leverage more than 30,000 de-identified fetal ultrasound images. The company said it provides consistent and precise measurements to enable new ultrasound users to perform fetal ultrasound measurements confidently.
“When I used Clarius OB AI while teaching OB ultrasound to a group of midwives, I was impressed by the accuracy of cursor placement on multiple scans, from crown rump length to biparietal diameter and femur length,” said Carolyn L. Gegor, an ARDMS certified midwife sonographer. “I found that after using the OB AI model, the students were more able to properly measure structures without the assistance of the AI. It was a quality improvement and time saver for me as a skilled scanner and an excellent teaching modality for those without previous scanning experience.”
Clarius Mobile said that ultrasound imaging is widely recognized as the gold standard for capturing accurate biometric measurements to monitor fetal wellbeing. However, equipment costs, lack of portability, and extensive training result in barriers to adoption. The company aims to broaden that access by integrating AI and specialized ultrasound technology.
The system is available now with the Clarius C3 HD3 wireless handheld ultrasound scanner in the U.S. and Canada. It is included with Clarius memberships. Once the user activates it on the Clarius app, OB AI automatically highlights key fetal anatomy and places calipers to calculate measurements that can be added to a patient’s electronic record from the app.
“OB AI is a testament to Clarius’ commitment to innovation in the handheld ultrasound market,” said Clarius President and CEO Ohad Arazi. “Our mission is to make high-quality ultrasound technology accessible and user-friendly, and with OB AI we’re pleased to be helping more clinicians provide accurate and efficient prenatal assessments, ultimately improving maternal and fetal health outcomes.”
