Ultrasound-guided procedures require excellent hand-eye coordination and practice. Trainees should gain this important skill with a phantom prior to performing procedures on patients. Currently available phantoms each have their own unique limitations. We propose an easily made, inexpensive, tissue-like phantom using a previously unreported material. The sonographic appearance of the phantom, with and without a 14-gauge needle, is compared with breast tissue, gelatin phantoms, and commercial phantoms. Target lesions can be produced using readily available materials. The proposed phantom is cheaper than commercial phantoms; performs better than gelatin phantoms, and is ultimately a superior practice tool for residents.
超声引导操作需要出色的手眼协调能力和实践经验。学员应在为患者进行操作之前，通过使用模型来获得这一重要技能。目前可用的模型各自具有独特的局限性。我们提出了一种使用以前未报道的材料制成的易于制作且价格低廉、类似组织的模型。该模型的超声表现（有和没有 14 号针）与乳腺组织、明胶模型和商业模型进行了比较。可以使用现成的材料来制作靶病变。与商业模型相比，所提出的模型更便宜；比明胶模型性能更好，最终是居民更好的实践工具。
