In this work, an ultrasound technique for extracting 3D palmprints is experimentally evaluated. A commercial ultrasound imaging machine, provided with a high frequency (12 MHz) linear array, is employed for the experiments. The probe is moved in the elevation direction by a motorized stepper stage and a teach step a B-scan is acquired and stored to form a 3D matrix representing the under skin volume. The data from the 3D matrix are elaborated to provide several renderings of the 3D ultrasonic palmprint. The results have been compared with corresponding samples obtained with conventional methods and the advantages of the ultrasound technique are underlined and discussed.

Abstract

In this work, an ultrasound technique for extracting 3D palmprints is experimentally evaluated. A commercial ultrasound imaging machine, provided with a high frequency (12 MHz) linear array, is employed for the experiments. The probe is moved in the elevation direction by a motorized stepper stage and a teach step a B-scan is acquired and stored to form a 3D matrix representing the under skin volume. The data from the 3D matrix are elaborated to provide several renderings of the 3D ultrasonic palmprint. The results have been compared with corresponding samples obtained with conventional methods and the advantages of the ultrasound technique are underlined and discussed.
