Fingerprint Image


This image of a fingerprint was produced with an Acuson Sequoia imager using a 15L8w transducer operating at a transmitted center frequency of 14 MHz. To achieve this image the transducer is positioned so that the image plane is just grazing across the fingertip. The spacing between the ridges in this finger is 400 microns. Note the similar azimuthal and axial resolution demonstrated when the ridges change from running horizontally to vertically through the image.
