Vscan Access R2 Feasibility Evaluation

This study is being done to evaluate if the Vscan Access R2 Ultrasound System can measure Fetal Heart Rate (FHR) in humans when compared against a reference device (GE Corometrics 170 Series Fetal Monitor), and to gather feedback from device operators on the usability of the device.

About this study

This study is being done to evaluate whether the Vscan Access R2 Ultrasound System Assisted FHR phantom testing conclusions can be extrapolated onto human fetal heart rate measurements, where CTG (GE Corometrics 170 Series Fetal Monitor) is to provide a reference value. It should be noted that the Vscan Access R2 Ultrasound System with Assisted FHR has a different intended use than CTG (momentary FHR value versus continuous monitoring of FHR patterns and trends) and this aspect is out of scope of this research.

Usability data will be gathered for further user experience optimization.

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Women aged 18 years or older at the time of consent;
  • By self-report, are in the 2nd or 3rd trimester of pregnancy;
  • Able and willing to provide written informed consent for participation;
  • Provide a completed Healthcare Verification Form which confirms the subject has received at least one diagnostic ultrasound during this pregnancy and has an uncomplicated pregnancy.

Treatment and study plan

GE VScan Access R2 Ultrasound System

Device

A diagnostic ultrasound imaging system manufactured by the study Sponsor.

GE Corometrics 170 Series Fetal Monitor

Device

A reference device to record a continuous fetal heart rate.

Primary outcomes

  1. Difference in Fetal Heart Rate as Measured by VScan Access R2 and Corometrics

    Time frame: 1 day - Up to 45 minutes of total scan time

    Absolute difference and variance in fetal heart rate (in BPM) measured using VScan Access R2 and Corometrics

Secondary outcomes

  1. GE Voluson P8 Confirmation of Visualization of Fetal Heart With Yes/No Answer Per Subject

    Time frame: 1 day - Up to 45 minutes of total scan time (5 minutes for this specific measurement)

    Visualization of fetal heart as acquired from the GE Voluson P8 to verify that the fetal heart was correctly identified during the image acquisition using Vscan Access R2. This is gathered through a Yes/No confirmation by device operator as to whether it was the fetal heart being scanned (once for each subject).

Other outcomes

  1. Number of Adverse Events (AE/SAE) Reported During Study

    Time frame: Collected from the time subject signs informed consent form to the time of completion of subject's scan session, estimated up to 4 hours

    Summary of type and number of AEs, SAEs reported/recorded during course

  2. Number of Scan Operators Who Completed Surveys Regarding Usability of Vscan Access R2 Device

    Time frame: 10 minute survey completed by scan operators upon completion their participation (only one day per user)

    Series of nine questions regarding usability, ease of use, and workflow

  3. Number of Device Issues/Complaints Reported by Site

    Time frame: Three weeks (estimated study duration)

    Device Issues, Complaints, and Malfunctions will be reported in a table (type and number)
