Near field

In general imaging ultrasound, the “near field” refers to the region closest to the transducer where the ultrasound beam is narrowest and resolution is highest. This zone is crucial for visualizing superficial structures like skin, muscle, and vessels with optimal clarity. Understanding and optimizing the near field ensures precise diagnostic imaging by leveraging the focused beam properties for detailed anatomical assessment.
