rasound transducer lose energy as they propagate through the tissue due to acoustic attenuation (absorption and scattering) and focussing effects. Consequently, reflections from deeper tissue features will appear weaker in the recorded signals. To compensate for this, a simple correction is applied assuming the attenuation within tissue follows the relation:</p>
