The document is a letter from Olga Torres Khoury at the Fetal Medicine Foundation certifying Sachin Nichite for assessing uterine artery flow after examining 3 submitted ultrasound images. The images were evaluated based on criteria such as being in the sagittal plane, having an insonation angle less than 30 degrees, a velocity over 60 cm/s, and a sample volume of 2.0 mm. Sachin passed the evaluation and his software license will now include assessing uterine artery flow to calculate risk of preeclampsia.
