Technology Development of Diagnostic Ultrasound System for Obstetric Imaging

May 9, 2026 updated by: United Imaging Healthcare North America, Inc.
This study collects obstetric ultrasound images from pregnant participants using the UIH uSONIQUE Nova diagnostic ultrasound system (uC7-1s transducer). The goal is to obtain standardized, high-quality images to support artificial intelligence (AI) algorithm development, AI training and validation, and automated obstetric measurement workflows. Results will support a premarket notification (510(k)) submission to the U.S. FDA.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Pregnant persons aged 18-45 years with single intrauterine pregnancy at 18-28 weeks gestational age presenting for obstetric care at Oregon Health & Science University, Portland, Oregon

To be eligible to participate in this study, an individual must meet all of the following criteria:

  1. Pregnant persons age 18-45 years
  2. Single intrauterine pregnancy
  3. Gestational duration: 18 - 28 weeks

Exclusion Criteria:

An individual who meets any of the following criteria will be excluded from participation in this study:

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Complete Fetal Biometric Image Set Collection
Time Frame: Day 1
Number of participants from whom complete fetal biometric image sets are successfully collected, including Biparietal Diameter (BPD), Head Circumference (HC), Abdominal Circumference (AC), and Femur Length (FL), in compliance with the study scanning protocol standards
Day 1

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Reference Dataset Creation
Time Frame: Within 4 months of study completion
Completion of independent reviews by two qualified obstetricians, resolution of measurement discrepancies through adjudication, and establishment of final ground truth measurements for all collected biometric data
Within 4 months of study completion
Incidence of Adverse Events
Time Frame: Throughout study participation, up to 4 months
Nature, frequency, and severity of adverse events (AEs) and serious adverse events (SAEs), including device-related complications and study discontinuations
Throughout study participation, up to 4 months

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 6, 2026

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
