Representative a) elevational LSF and b) lateral LSF for no paddle and TPX 2.5 mm paddle. Lexan 375 μm paddle LSFs exhibited similar shapes to no paddle LSFs. Lateral LSF was calculated with and without beamforming corrections. In the elevational direction, FWHM values were increased up to 17% and sidelobe levels were increased up to 4 dB when imaging through a paddle. FWHM values in the lateral direction were only increased 2% in both paddles when beamforming corrections were implemented.
