简要总结
Thisstudy is a prospective data collection study.
The main objective of the study is to collect2D, M-mode and 3D ultrasound imaging in the early first trimester pregnancies(5 weeks to 10 weeks and 6 days) and in gynaecological subjects to check thefeasibility of automated detection and quantification in early normal andabnormal pregnancies. In order to build clinically useful algorithms, the datashould represent a variety of situations that is found in current practice; thedataset should hence contained at least the following:
· Firsttrimester pregnancies (normal and abnormal such as ectopic pregnancies)
· Surroundinganatomical structures (such as ovaries, Fallopian tubes and Douglas cul-de-sac)
· Imagingdata with features that can be confused with early pregnancy (such as normaland abnormal uterine findings in non-pregnant women)
· Imagesacquired with different ultrasound modes: standard 2D view, M-mode (fetal heartrate), 3D.
Thedata collection study will be performed at Gunasheela Surgical and MaternityHospital, Gunasheela IVF centre, Bangalore (site 1) and Thane Ultrasoundcentre, Mumbai (site 2), both are referral centres in India.
De-identified2D, 3D ultrasound images and videos of 250 women presenting with: normal first trimester pregnancies(180), abnormal first trimester pregnancies (30), normal (20) or abnormal (20)pelvic scan will be shared with the sponsor (125 subjects total per site).
Datacollection will be done on the commercial registered ultrasound devices of thecentres (Philips Affiniti 50/70, Philips Epiq 5/7) and on a commerciallyreleased ultrasound device from the sponsor (ClearVue 650/850). All deviceswill be used within their intended use.
Studywill be registered in the CTRI website as per local regulations (India).
The variety and number of data/image sets neededto build accurate machine learning algorithms is high and an amendment will beproposed if the data sets do not meet the researchers’ requirement to buildaccurate algorithms as decided by the researchers or after review ofalgorithms’ results by clinicians/KOLs (interviews/focus group, etc…
