The use of beam angulation to overcome anisotropy when viewing human tendon with high frequency linear array ultrasound.

Anisotropy is the property of tendons, nerves and muscles to vary in their ultrasound appearance depending on the angle of insonation of the incident ultrasound beam. Loss of reflectivity in tendons may also denote underlying disease. We describe beam angulation, a simple technique available with most modern ultrasound machines, which allows the operator to overcome the potential pitfall of anisotropy in ultrasound assessment of peripheral tendons.
