This research aims to understand how well advanced computer software, artificial intelligence (AI), can help support the quality of pregnancy ultrasound scans and if it's use is cost effective
Sponsored by King’s College London
In partnership with NHS hospitals and King's College London university spinout company 'Fraiya', and funded by the National Institute for Health and Care Research (NIHR)
We're testing new artificial intelligence, AI, software to support ultrasounds by:
- Helping sonographers capture and measure scan images more efficiently.
- Allowing independent experts to double-check scans remotely.
- Using additional AI software on saved images, to help spot more conditions earlier during the double-check of scans — so families can get the right support sooner.
This research is taking place in four NHS hospitals across the UK.
What Does This Mean for You?
If you're having your 18–22 week mid-trimester scan at a participating hospital:
- You might be emailed or contacted by phone before your appointment to provide you more information
- A few weeks before your appointment, you may be asked to complete an online form (a consent form) to say you agree to take part.
- On the day of your scan, we may check you are still happy to take part, or offer to help you complete an online or paper consent form (language translation is available).
- If you agree to take part, you will randomly be assigned to have a scan with AI-support or without AI-support. To ensure fairness neither you nor your sonographer can choose which group.
- The sonographer will complete your scan either with AI-support or as usual. Your scan images and measurements, scan timings and some of your health data related to pregnancy will be anonymised and saved for the research.
Not everyone will be invited - but knowing about the study helps you feel prepared.
You can ask questions, opt out, or get in touch with the study team at any time.
What are the benefits of taking part?
If you have your scan in the usual way - there will be no differences in your care: Your scan is performed in the same way as usual and we will compare all the results with the AI supported group.
If the sonographer uses the Fraiya software - the scan is still performed in the usual way but with computer assistance: The aim of the AI software is to make collecting images and measurements easier and more reliable. In addition, in cases where no follow up scans are booked, the scan image data will be anonymised and transferred to the remote sonographers and doctors, at our research partner 'Fraiya Ultrasound', to double check the scans.
Other benefits of the AI-supported group might include:
- Potential Improved Detection: AI tools may help identify conditions that are sometimes missed in standard scans, potentially leading to earlier support and care.
- Enhanced Efficiency: If randomised to the 'AI group' - AI-assisted scans may streamline the process, making it quicker and more consistent for both patients and staff.
- Extra Review: If randomised to the 'AI group' - A second expert review of scan images adds an extra layer of reassurance without replacing standard care.
Whether having an AI-supported scan or not other benefits may include:
- Contributing to Potentially Better Future Care: By taking part, families contribute to research that could improve pregnancy care for others.
- Optional Feedback Opportunities: Participants may be invited to share their experiences through surveys or interviews, helping shape future technology and services.
What are the risks I should consider if taking part?
You won't know if you are in the usual scan group or the AI-assisted group until the day of your scan. For both groups you should consider:
- Emotional Impact: As with any scan, unexpected findings can be distressing. Support and follow-up care will be provided as per NHS standards.
- Time Commitment: Consenting to take part takes an additional 15 minutes. In addition, the optional surveys or interviews take additional time (15 for surveys and up to 45 minutes for the interview), but participation is entirely voluntary.
- Data Privacy: Personal and health data will be securely stored and anonymised, but as with any research, there is a very small risk of data breach. Strong safeguards are in place.
If the sonographer performs your scan with AI-support, additional considerations include:
- Potential for follow-Up Scans: If the AI scan images are unclear or something unexpected is found during the double check of results, some research participants may be asked to return for another scan.
Can you tell me how I can give feedback on the research as a participant?
We would like like to hear the diverse opinions of people that take part in this study. For informal feedback, or if you have any questions you can use this form.
Why do the surveys and interviews matter?
As part of the study we will invite some participants to offer feedback by having an online interview and/or an online short survey.
Your feedback helps us:
Improve how AI tools are used in clinics.
Make care more patient-centred.
Ensure future technologies meet real needs.
Optional Interview
A small number of survey participants may be invited to an optional one-to-one online interview.
Interviews are usually held via video call and last around 45 minutes, and you will receive a small reimbursement for your time.
You’ll be asked to reflect on your care and experience in more detail.
You can skip any questions or stop at any time — it’s completely voluntary.
Optional survey
A short survey - some participants will be invited to offer their opinions about the use of AI for pregnancy scans.
The survey will take about 15 minutes and can be completed online. If needed, it can be completed by phone, or with an interpreter.
You’ll be asked about your experience of the scan, communication with staff, and how supported you felt.
Want to find out more?
Even if you’re not taking part, we’d love for you to know this research is happening.
It’s part of a wider effort to improve care for all families. You can keep up to date in our "Study News and Updates" page.
If you’re invited to take part your scan will still follow NHS standards.
