Purpose: To construct a low cost phantom module and evaluate the feasibility of its usage for learning sono-guided interventional procedures.
Methods and Materials: The dry and intact jelly fig achenes were homogenized with cycle blender at the low speed for 2 minutes in 1000 ml of tape water. Filtrates obtained by filtration through cheeseclothes. Cherry tomato and sausage were added to the jelly curd to simulate cystic and solid lesions. The approximate time required for jellification was about 3 to 15 minutes according to the concentration of jelly fig achenes need. To determine the ideal concentration of the phantom, different concentrations of jelly fig achenes were evaluated independently by experienced radiologists.
Results: The jelly curd phantom was constructed with total cost of less than US$1.50. These phantoms are relatively easy to prepare, taking approximately less than 15 minutes preparation time. The feasibility of its usage was confirmed by experienced radiologists. The appropriate concentration is 1.5% of jelly fig achenes which simulates the human tissue at room tempature in physical properties.
Conclusion: The jelly curd can be readily shaped into any desired form. The simulated target materials were easy to add for both cystic and solid lesions. This phantom is disposable due to low cost and easy to prepare. This phantom is an useful tool for learning sono-guided interventional procedures.
