In this work, 3D ultrasonic images of the internal region of the palm of the human hand are presented and analyzed in order to evaluate the ultrasonic technique for biometric recognition purposes. A commercial ultrasound imaging machine provided with a high frequency (12 MHz) linear array has been employed. The probe is moved in the directional orthogonal to the array and at each step a B-scan is performed and stored to form a 3D matrix. The data from the the 3D matrix are elaborated for achieving 3D ultrasonic palmprints. The results have been compared with corresponding sample obtained with conventional methods and the advantages of the proposed technique are underlined and discussed.

Abstract

In this work, 3D ultrasonic images of the internal region of the palm of the human hand are presented and analyzed in order to evaluate the ultrasonic technique for biometric recognition purposes. A commercial ultrasound imaging machine provided with a high frequency (12 MHz) linear array has been employed. The probe is moved in the directional orthogonal to the array and at each step a B-scan is performed and stored to form a 3D matrix. The data from the the 3D matrix are elaborated for achieving 3D ultrasonic palmprints. The results have been compared with corresponding sample obtained with conventional methods and the advantages of the proposed technique are underlined and discussed.
