You may apply for accreditation on any one trimester, any combination of two, or all three trimesters. 

  • All three Trimesters: one exam for each trimester is required. 

  • Trimester-Specific: your site will only be accredited in the specific trimester(s) you select. Required exams for trimester-specific obstetrical are as follows: 

    • One trimester only (1st, 2nd, or 3rd):  Two exams (if 1st trimester, both must be endovaginal) 

    • Any combination of two trimesters: 1 exam of each trimester (if 1st trimester is selected, exam must be endovaginal) 

When submitting obstetrical images, choose examinations of a gestational age that allow all anatomy to be well demonstrated.


Complete documentation/survey means a series of several images throughout the entire organ in two planes. For example, from one side of the organ to the other in the longitudinal plane and from superior to inferior in the transverse plane.
