The visibility of an object imaged with ultrasound depends on the degree to which it reflects the incoming ultrasound back to the probe sensor. Snell's law requires that the angle of incidence (acoustic wave) is equal to the angle of reflection (backscatter) for a flat, hard surface. Therefore, maximum reflection occurs when the direction of the wave is perpendicular to the reflecting surface. By convention, this sonic angle is defined as zero. For linear probes, the needle axis must be parallel to the probe surface in order to obtain strong reflections from the smooth needle surface. In clinical practice, this does not happen because the angle of the sound waves usually varies between 20 and 70 degrees during ultrasound-guided nerve blocks. In layman's terms, when the probe is placed flat on the skin, the needle usually forms an oblique angle with the surface of the probe. When this happens, the sound waves will not be reflected back to the probe.
