Fetal monitoring relies heavily on ultrasound imaging, which offers details on fetal growth, placental function, anatomical issues, and overall gestational health. Adding artificial intelligence (AI) to ultrasound devices improves image capture and interpretation, helping clinicians reduce errors linked to user skill and variability.
AI systems built into modern ultrasound machines automatically adjust settings like gain, focus, and depth as the scan progresses. This leads to clearer images regardless of the operator’s experience. According to GE HealthCare, such automation decreases manual adjustments, resulting in better visualization of fetal parts, higher accuracy, and shorter exam times.
AI uses machine learning models, especially convolutional neural networks (CNNs), to examine ultrasound images for normal and abnormal features. This helps detect issues that a human might miss due to fatigue or error. For instance, AI supports fetal biometry by measuring key parameters like head circumference, femur length, and abdominal circumference consistently. Automated measurements reduce differences that occur between various sonographers.
Beyond size measurement, AI aids assessments of placental health, fetal heart rate, and growth. Some AI applications link ultrasound data with electronic medical records (EMRs), offering clinical decision support such as suggesting follow-up tests or flagging high-risk cases like preeclampsia and gestational diabetes. These tools provide doctors with practical information drawn from large databases, helping with earlier intervention and personalized care.
Jeffrey Thatcher at the University of North Carolina’s Radiology Department notes that AI algorithms automate tasks like pathology detection and measurements. This not only raises diagnostic accuracy but also improves workflow, an important benefit as U.S. practices handle more patients with fewer staff.
Efficiency remains important in medical settings, especially in obstetrics and gynecology where patient volume can be high and care time-sensitive. AI ultrasound systems help automate workflows in multiple ways.
Consistency in ultrasound quality can be difficult because of varied operator skills and limited specialists. AI tackles this by automating routine tasks such as setting image presets, organ identification, and autofocus.
At the Radiological Society of North America (RSNA) 2024, companies showed how AI ultrasound platforms reduce sonographer workload. For example, Siemens Healthineers’ AI Abdomen platform lowers hand movement by up to 89% compared to manual exams, which reduces the risk of repetitive strain injuries. This is important for keeping technicians on staff and sustaining scan quality during long shifts.
Systems like Philips’ Elevate provide Quick Launch presets and AutoElastQ features that speed up exams such as liver elastography, adaptable for obstetric use. AI also gives instant feedback on image quality and measurement accuracy after scans, helping sonographers improve and ensuring consistent results.
More efficient scans mean more patients can be seen and wait times drop. GE HealthCare’s SonoLyst AI shortens second trimester fetal exams by up to 40%, enabling clinics to manage heavier caseloads without lowering standards. Quicker scans free clinicians to spend more time discussing care with patients.
The U.S. faces shortages of qualified sonographers and radiologists. AI ultrasound systems ease this issue by streamlining workflows and helping less experienced staff perform complex imaging more confidently. For instance, Samsung Medison’s AI-enabled Z20 ultrasound supports consistent diagnoses even for patients with high body mass indexes, which can make scanning harder.
Automated image analysis and standardized measurements reduce workload on physicians and technologists, letting practices serve more patients without losing diagnostic precision.
Some healthcare providers have concerns about AI, including bias, reliability, and fears it may replace clinicians. Research from UT Southwestern Medical Center shows fewer than 20% of obstetricians and gynecologists believe AI will fully replace doctors. Instead, over 42% expect AI to create new jobs by assisting clinicians rather than replacing them.
Alan Kramer, M.P.H., states that AI should be viewed as a tool to support diagnosis, training, and patient care by recognizing complex patterns beyond human ability. He advises against seeing AI use as “cheating” and encourages acceptance as a supplement to clinical skills.
Viewing AI as a partner fits well with U.S. healthcare needs, where staff shortages and heavy patient loads require technology that speeds routine tasks without compromising diagnostic quality.
AI ultrasound works best when combined with health information systems like EMRs. AI in EMRs can generate alerts for high-risk pregnancies by analyzing multiple factors such as past complications, maternal health, and ultrasound data.
For example, AI algorithms comparing ultrasound measurements with patient records can predict risks like preterm labor or fetal growth issues. This helps clinicians plan tests and care more proactively. Such integration encourages preventive care and prioritizes interventions to improve mother and child health.
Data synthesis and predictive analytics also assist administrators in resource planning. Clinics can better forecast needs for specialized tests, NICU admissions, and staff schedules by using real-time imaging data alongside historical records.
AI progress comes alongside hardware improvements that make use easier and more comfortable for clinicians.
Portable, wireless probes allow flexibility and enable imaging in various places such as remote clinics or bedside, helping rural areas with limited specialist access. Ergonomic designs including adjustable machine heights, touchscreens, and lighter transducers reduce physical strain, which supports technician retention and health.
These hardware upgrades combined with AI automation cut down on repetitive manual tasks. Sonographers and doctors can then focus more on patient communication rather than handling equipment.
Fetal ultrasound requires skill and experience. AI-powered simulation tools let trainees practice procedures in virtual settings without needing patients. This builds skill and confidence before working on real cases, supporting quality in obstetric imaging.
Virtual training also reduces dependence on expert mentors—a benefit where faculty are in short supply. Trainees get immediate feedback on image collection and measurement accuracy, speeding up learning and ensuring consistent standards nationally.
Future work aims to improve fetal heart rate monitoring algorithms to better predict newborn outcomes like low Apgar scores or NICU needs. Developments in ultrasound radiation imaging, volumetric 3D/4D views, and augmented reality (AR) tools are underway to support diagnosis and procedures.
The COVID-19 pandemic and growing telehealth demand have sped up use of portable point-of-care ultrasound (POCUS) and tele-ultrasound platforms. These allow remote evaluations in underserved areas and are valuable for rural or low-resource U.S. communities. When paired with AI, these devices can deliver rapid diagnostics similar to larger hospitals, helping reduce healthcare gaps.
By selecting and implementing AI ultrasound technologies carefully, medical practices across the United States can improve patient care, reduce workflow delays, and better manage clinical staff to meet increasing demands.
AI-powered ultrasound is becoming a regular part of obstetric imaging and operations in the U.S. It offers improvements in fetal assessment accuracy, workflow automation, and training. For medical leaders, adopting these technologies is a practical step to sustain quality and efficiency in pregnancy care services.
AI plays key roles in diagnosis improvement, better training, and enhanced patient outcomes. It helps validate diagnoses by recognizing patterns from vast data sets.
Pattern recognition allows AI to analyze previously entered data to determine normal and abnormal results, assisting doctors in making more informed decisions.
EMR systems alert OB-GYNs about potential risks, such as preterm birth, based on individual patient data and learned patterns.
AI-enhanced technology processes Pap smear slides for higher quality analysis and reduces screening errors by identifying areas of interest for review.
AI in ultrasound can automatically recognize structures for measurement, aiding doctors in providing accurate fetal assessments more efficiently.
AI-based simulation platforms allow trainees to practice ultrasound image gathering, offering feedback on their performance without involving patients.
Key concerns include bias in AI’s data analysis due to physician bias and the stigma that using AI may be perceived as ‘cheating’ by colleagues.
Bias can distort AI’s understanding of what is considered normal or abnormal, potentially impacting patient care, though many current uses remain unbiased.
Future applications may include advanced fetal heart rate monitoring to better predict fetal complications, although it requires comprehensive data context.
OB-GYNs should embrace AI as a valuable support tool that enhances their abilities, rather than fearing that it will replace their roles.
