“…Abuhamad et al have introduced the 6-step approach to the performance of the focused basic obstetric ultrasound examination [7] and have validated its feasibility and accuracy [8]. With proper training, the 6-step approach may be completed in 5 min [8]; it is a most efficient modality in the time-constrained patient encounter of an outreach setting. Though this approach identifies the majority of risk factors impacting maternal morbidity and mortality, it does not standardize the approach to fetal anatomic assessment.…”

“…The study was carried out over a 5 year period on 1396 pregnant women presenting to SANA in various locales in the Lebanese outreach setting for dating and detection of abnormalities. All pregnancies were scanned utilizing Abuhamad et al's previously described standardized 6-step approach [7,8] in order to determine fetal position, ascertain viability, number of fetuses, placental location, amniotic fluid index as well as obtain fetal biometry. In addition, SANA utilizes a standardized technique, the 3-sweep approach, for fetal anatomic assessment.…”

“…Abuhamad et al reported on a standardized 6-step approach for the performance of the focused obstetric ultrasound examination. The 6-step approach serves as an introductory method for trainees in academic as well as limited resource settings and after training, may be completed in under 5 min [7,8]. However, we still lack a standardized complementary method that clarifies how to manipulate the transducer on the maternal abdomen in order to navigate through and carry out a full fetal anatomic assessment.…”

This retrospective study aims to describe a standardized screening technique “the 3-sweep approach” for fetal anatomic assessment in the outreach setting. The study was carried out on 1396 pregnant women referred for an obstetric ultrasound for pregnancy dating and detection of abnormalities in a limited resource setting in Lebanon. All pregnancies were scanned utilizing a previously described standardized 6-step approach and the 3-sweep approach for fetal anatomic assessment. The first sweep examines the fetal head and face, the second examines the spine, and the third examines the chest, abdomen, and pelvis. Positive findings were referred for a detailed ultrasound examination at a referral center. There were a total of 1157 women, at >14 weeks gestation, included in the study. The median gestational age was 24 weeks 4 days (14 weeks 0 day–41 weeks 1 day). The 3-sweep approach was completed in all pregnancies with a total time of under 1 min. A total of 33/1157 (2.9%) fetuses had structural abnormalities detected. Confirmation of the 3-sweep findings was made by comprehensive imaging at a referral center (8/33 = 24.2%) or thorough review of 3-sweep images (25/33 = 75.8%). We found the 3-sweep approach to be an effective mode of screening for structural fetal abnormalities. Though it requires skill in probe manipulation and knowledge of fetal anatomy, its incorporation into routine evaluation in the outreach setting will help identify at-risk fetuses. Depending on the available facilities, this may facilitate proper referral and management to optimize neonatal outcomes and minimize maternal risks. Based on our experience, it is a time-efficient and complementary technique to the 6-step approach.

“…It follows a customized workflow to scan the desired anatomical location in a consistent way. The robotic US acquisition follows a generic path that is not specific to any scan pattern prescribed for antenatal scanning, like the six-step approach recommended by the International Society of US in Obstetrics and Gynecology (ISUOG) [11].…”

Maternal health remains a pervasive challenge in developing and underdeveloped countries. Inadequate access to basic antenatal Ultrasound (US) examinations, limited resources such as primary health services and infrastructure, and lack of skilled healthcare professionals are the major concerns. To improve the quality of maternal care, robot-assisted antenatal US systems with teleoperable and autonomous capabilities were introduced. However, the existing teleoperation systems rely on standard video stream-based approaches that are constrained by limited immersion and scene awareness. Also, there is no prior work on autonomous antenatal robotic US systems that automate standardized scanning protocols. To that end, this paper introduces a novel Virtual Reality (VR) platform for robotic antenatal ultrasound, which enables sonologists to control a robotic arm over a wired network. The effectiveness of the system is enhanced by providing a reconstructed 3D view of the environment and immersing the user in a VR space. Also, the system facilitates a better understanding of the anatomical surfaces to perform pragmatic scans using 3D models. Further, the proposed robotic system also has autonomous capabilities; under the supervision of the sonologist, it can perform the standard six-step approach for obstetric US scanning recommended by the ISUOG. Using a 23-week fetal phantom, the proposed system was demonstrated to technology and academia experts at MEDICA 2022 as a part of the KUKA Innovation Award. The positive feedback from them supports the feasibility of the system. It also gave an insight into the improvisations to be carried out to make it a clinically viable system.
