Far field

In General Imaging, the far field refers to the region beyond the focal zone of an ultrasound beam. This area exhibits reduced resolution and weaker signal strength due to the divergence of sound waves and increased attenuation as they travel deeper into tissues. While image quality may diminish in the far field, it remains crucial for visualizing deeper structures and assessing organ boundaries. Optimized ultrasound techniques and proper gain adjustments help compensate for these effects, ensuring diagnostic utility even at greater depths. Understanding far field characteristics is essential for accurate image interpretation and optimizing General Imaging ultrasound studies.
