Announcing a new article publication for
BIO Integration journal. In this article the authors Craig S. Carlson and Michiel Postema, from University of the Witwatersrand, Johannesburg, South Africa and Tampere University, Tampere, Finland discuss deep impact of superficial skin inking: acoustic analysis of underlying tissue.
Skin tattoos are a common decoration, but profound scientific study on whether a skin tattoo alters the acoustic response from superficial tissues, and therefore from underlying tissue, was previously lacking; thus, any quantitative effects were unknown.
This study is the first to investigate the nature of artifacts in ultrasound images, which have been observed to originate from tattooed skin. The work was conducted theoretically and experimentally using extremely simplified cases of perfectly flat and homogenous layered media and in tattooed pork. The measured speeds of sound of tattooed materials were higher than those of their uninked counterparts.
