“…They are used for routine testing and calibration of grey-scale ultrasound scanning equipment so great effort is taken to control factors like the speed of sound through the phantom and the coefficients related to scattering and attenuation. [2][3][4] As such, they can be time-consuming and expensive to produce, which typically precludes them from being used to simulate procedural ultrasound. 4 In contrast to the tissue-like phantoms that mimic the acoustic properties of tissue, biopsy phantoms are developed to represent the sonographic appearance of tissue.…”

Various medical specialty organizations and the Agency for Healthcare Research and Quality (AHRQ) have advocated using ultrasonography to guide central venous cannulation. It is surprising then, that very few instructional models have been described to teach this technique. Consequently, we developed a model to teach ultrasound-guided central venous access. This paper presents a recipe for an ultrasonographic model or “phantom” that is easily made, inexpensive and simulates vessel cannulation extremely well.

“…U ltrasound phantoms used to mimic human soft tissue are required to have the ultrasound properties of actual human soft tissue, such as the ultrasound propagation velocity, attenuation coefficient, acoustic impedance, and texture. [1][2][3][4][5][6] Ultrasound phantoms are used not only to train users on the ultrasound diagnostic apparatus but also to practice ultrasound-guided needle and blind catheter insertion procedures without risk to real patients. [7][8][9][10][11][12] Moreover, for ultrasound diagnostic apparatus engineers, ultrasound phantoms are also essential for the development and testing of the apparatus.…”

“…In addition, noncommercial (ie, laboratory made) phantoms are fixed by gelatin or agar as a gelling agent. [5][6][7]9,20,21 These gelling agents are easy to handle and do not require special equipment for the fabrication of the phantom. However, the ultrasound properties of these laboratory-made phantoms are slightly different from the characteristics of human soft tissue.…”

For medical workers, ultrasound phantoms for human soft tissue are used not only for accuracy management of ultrasound diagnosis but also to aid ultrasound-guided needle and blind catheter insertion training without risk to real patients. For the phantoms, ultrasound characteristics and a texture are required to mimic the human soft tissue. The proposed phantom was composed of sodium alginate, calcium sulfate dihydrate, trisodium phosphate 12-hydrate, glycerol, and water. The propagation speed, attenuation coefficient, acoustic impedance, and texture of the proposed phantom were almost the same as those of human soft tissue. Expensive chemicals and special equipment are not required.

It provides an inexpensive, radiationfree way to visualize the airway, identify tumors, assess thyroid nodules, and guide fine-needle aspiration of the salivary glands, lymph nodes, and thyroid.…”

ith the rise in popularity of ultrasound imaging, the demand for effective training tools has exponentially increased. Ultrasound models, or phantoms, are widely popular for facilitating the learning of hand-eye coordination needed for ultrasound imaging and ultrasound-guided procedures. Unfortunately, many available ultrasound models are expensive and have limited life spans. 1 Gelatin is frequently used to create phantoms because of its ease of use and low cost, and gelatin models have been used in fields such as anesthesiology, pain management, general surgery, and medicine. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] For the otolaryngologist, as well as other providers treating head and neck disorders, ultrasound in an invaluable tool for visualizing head and neck structures. It provides an inexpensive, radiationfree way to visualize the airway, identify tumors, assess thyroid nodules, and guide fine-needle aspiration of the salivary glands, lymph nodes, and thyroid. 14,18-20 However, similar to other fields of medicine in which ultrasound is used, training tools for head and neck procedures can be expensive and difficult to acquire. With this factor in mind, we developed 2 simple gelatin-based phantom models that can be used for instruction on fine-needle aspiration technique for the head and neck. TECHNICAL INNOVATIONThe rise in popularity of ultrasound imaging has seen a corresponding increase in demand for effective training tools such as phantom models. They are especially useful for teaching and practice of invasive procedures, such as fine-needle aspiration of lesions of the head and neck. We have created 2 gelatin models out of inexpensive, commonly available materials that can be used in sequence to learn head and neck fine-needle aspiration. Fundamental skills can be learned first on the flat, rectangular model, whereas the second, cylindrical model more closely represents human anatomy and can be used to develop more advanced technique.
