Ultrasonography in veterinary medicine serves a vital role in the diagnosis and management of various medical conditions by allowing noninvasive visualization of internal structures. Veterinary students face many challenges in gaining hands-on experience with ultrasound equipment and developing competencies in ultrasonography. This is largely due to the limited access and ethical dilemmas of live animal models and the high cost of commercial phantoms. To solve these issues, the niche of cost-effective amateur models has exponentially increased. However, while these at-home models solve the financial issues associated with commercial phantoms, they still lack the realism and fidelity necessary to simulate the real-time feedback needed to gain the spatial awareness of this dynamic imaging modality. To foster successful day-one-ready veterinary students, The Ohio State University College of Veterinary Medicine acknowledged that a better solution should be possible. A prospective anatomic study was performed to recognize the imaging anatomy and usability of a new model termed the Danny Phantom. This model was developed by testing various amateur phantom materials from both the literature and self-discovered. These materials were analyzed and deemed satisfactory versus unsatisfactory based on fulfillment of predetermined criteria of an ideal phantom model. It was determined that real fixed organs can be encased in traditional bovine gelatin to produce an ultrasound phantom with recognizable parenchyma. Other additives can be included to give the phantom an imitated peritoneal space and prevent spoilage of the gelatin for an extended period of time.
超声检查在兽医学中发挥着至关重要的作用，通过对内部结构进行非侵入性可视化，辅助诊断和管理各种病症。兽医专业的学生在获取超声设备的实践经验以及培养超声检查技能方面面临诸多挑战。这主要是由于活体动物模型的获取受限和伦理困境，以及商业仿体的成本高昂。为了解决这些问题，性价比高的自制仿体的市场份额呈指数级增长。然而，虽然这些家用仿体解决了与商业仿体相关的资金问题，但它们仍然缺乏模拟动态成像模式所需的实时反馈以获得空间感知能力所必需的真实感和逼真度。为了培养从第一天起就能胜任工作的兽医学生，俄亥俄州立大学兽医学院认识到应该有可能找到更好的解决方案。开展了一项前瞻性解剖学研究，以识别一种名为“丹尼仿体”的新模型的成像解剖结构和可用性。该模型是通过测试文献中的各种自制仿体材料以及自行发现的材料开发而成的。根据理想仿体模型的预定标准，对这些材料进行分析并判定其是否令人满意。结果表明，真正的固定器官可以包裹在传统的牛明胶中，制成具有可识别实质的超声仿体。还可以添加其他添加剂，使仿体具有模拟的腹膜腔，并防止明胶在较长时间内变质。
