Is there any impact on the fetus if too many B-ultrasounds are performed?

As a routine and important examination method during pregnancy, B-ultrasound works by using ultrasound imaging, which is non-ionizing radiation and relatively safe for both the human body and the fetus. Clinical studies have shown that when used appropriately and in accordance with established guidelines, B-ultrasound examinations do not have negative effects on fetal growth and development. Although ultrasound is a form of energy, the intensity used in medical diagnostics is far below the threshold that could potentially harm the fetus. Therefore, pregnant women need not be overly concerned about potential adverse effects on the fetus due to an increased number of B-ultrasound examinations. Any medical examination should follow medical advice and be performed only when necessary, to ensure the safety of both mother and child.
