Training phantom for ultrasound guided biopsy

Area of Science:

• Medical Education
• Biomedical Engineering
• Radiology Training

Background:

• Commercial ultrasound biopsy phantoms are expensive and have limited usability.
• Radiologists require effective, accessible tools for practicing biopsy skills.
• Developing cost-effective training models is crucial for medical education.

Purpose of the Study:

• To develop an affordable, in-house phantom for ultrasound-guided biopsy training.
• To create a model that replicates human tissue properties using readily available materials.
• To assess the longevity and reusability of the developed phantom.

Main Methods:

• A gelatin-based phantom was formulated using inexpensive, common materials.
• The phantom was designed to mimic the physical characteristics of human tissues.
• Its performance and durability were evaluated over time, particularly concerning needle-induced tears.

Main Results:

• The gelatin phantom successfully recreated conditions for practicing ultrasound-guided biopsy.
• The model remained functional for several weeks, offering a cost-effective solution.
• While older gelatin (over a month) showed slower tear bonding, fresh phantoms could be quickly prepared, and components recycled.

Conclusions:

• An in-house gelatin phantom provides a viable, low-cost alternative for ultrasound-guided biopsy training.
• The model effectively simulates human tissue for skill development.
• Its ease of creation and component recycling enhance its practicality and sustainability for medical training programs.
