Abstract

In ultrasound imaging, radiologists often need to attain different penetration depths. It is well known that the maximum penetration depth decreases when the frequency of the ultrasound increases. Based on related research and reviewing of recent patents, we suggest an approach based on Golay coding to improve the penetration depth. During our simulations, we successfully achieved a maximum penetration depth of 60 cm as the frequency ranged from 0.0625 to 4 MHz with uniform signal to noise ratio of 6 dB. Implementing this result will mean that a unique 4 MHz transducer can be used for a variety of examinations where probes of different frequencies were needed.
