Ultrasound imaging is widely utilized in the medical field, particularly for monitoring fetal development during pregnancy. This technique leverages high-frequency sound waves to create real-time images of the fetus in the womb. It is invaluable for evaluating the health of the fetus, checking for physical abnormalities, determining gestational age, and observing fetal movements and heart rate.

Ultrasound is non-invasive and does not involve ionizing radiation, making it particularly safe for both the mother and the developing fetus. This ability to provide detailed images and dynamic assessments during different stages of pregnancy is what makes it a common and essential application in obstetrics.

In contrast, detecting bone fractures typically relies on X-rays, as ultrasound is not effective in imaging bony structures. Similarly, while ultrasound can sometimes aid in evaluating soft tissue structures in the brain, it is not the primary method for identifying brain tumors, with MRI and CT scans being more commonly used. Furthermore, assessing lung function usually requires different imaging modalities and techniques, as ultrasound primarily visualizes soft tissues and is not suitable for evaluating lung capacities or functions directly.
