Sector width

Sector width in general imaging refers to the angular spread of the ultrasound beam emitted by a curvilinear or phased array transducer. Adjusting this parameter allows sonographers to optimize the field of view for specific anatomical structures or regions of interest. A wider sector provides a broader overview, useful for initial surveys, while a narrower sector enhances frame rate and resolution, ideal for detailed examination of smaller areas. Proper sector width selection is crucial for effective general imaging, enabling accurate diagnosis and improved image quality.
