Realistic and inexpensive ultrasound phantoms to demonstrate aortic aneurysm and aortic dissection.

Introduction: Using ultrasound to evaluate for the presence of aortic pathology is a common procedure in the emergency department. Phantoms are models that are used to simulate clinical conditions for teaching ultrasound-related skills. To date, no 'homemade' phantom has been created to model aortic aneurysms, and no phantoms exist to model aortic dissection.

Prolonging the Shelf Life of Homemade Gelatin Ultrasound Phantoms.

A significant limitation of homemade phantoms is shelf life. Our goal was to compare the impact on shelf life of easily obtained additives. Fifteen additives were mixed into a gelatin-psyllium hydrophilic mucilloid fiber phantom; three of these additives were used as a layer on top of the phantom.
