Expertise in the utilization of procedure-guided ultrasonography has become increasingly important within the field of Emergency Medicine. Consequently, ultrasound phantoms have been implemented as simulation tools in introductory courses. This study of the surface behavior of gelatin blocks was performed to describe the behaviors of phantoms for ultrasound training.


Gelatin blocks of varying preparation techniques and component concentrations were tested on exposed and latex-coated surfaces to determine the variation in surface disruption and force–displacement characteristics of each of the surfaces tested.


Gelatin blocks made at a cooler temperature than current recommendations have a more durable surface. Latex-coated blocks have the most durable surface.


Gelatin blocks made at a lower temperature than current recommendations result in a more desirable phantom. A re-usable latex coating can add to the durability of the phantom.
