We do not have any material that works well with UltraSound technology for producing clear images for diagnostics and skill training.
Flexible elastomers that simulate biological tissue are the goal for making ultrasound phantoms for skill training and simulation. Ultrasound technology requires a high speed of sound through the elastomer, or low impedance, and the ability for the sound wave to penetrate the material easily without the risk of scattering or high attenuation which results in loss of image data. Some people have had moderate but not consistent results using our Ecoflex silicone with the inclusion of additives such as corn starch, liquid cellulose, flour, or psyllium hydropholic mucilloid fiber. Image quality was not ideal in this scenario and the targets for imaging in the material were very close to the surface (approximately 2mm). Ideal ultrasoundable material must be able to get clear images from a target at any depth for clinical diagnosis.
