Paper Abstract

Conventional ultrasound systems acquire an image by scanning the environment successively line by line. This limits the frame rate. Furthermore the used conventional signal affects the resolution and the penetration depth. In this contribution we propose to use modified mutually orthonormal Hermite series in a coded excitation system yielding a full image in only one transmission. Therefore a higher frame rate can be achieved. Additional properties of these codes offer the possibility to increase the resolution and the penetration depth. Preliminary results show the effectiveness of the proposed approach.
