    摘要:

    〔摘 要〕 目的:基于鼻咽部计算机断层扫描(CT)与磁共振成像(MRI)图像融合的 3D 造型技术,制作鼻咽部三 维虚拟模型,探讨其在临床实践教学模式及临床工作中的意义。方法:首先对 3 例鼻咽癌患者鼻咽部进行 MRI 扫描得到 DICOM 数据,利用医学影像技术分割并重建鼻咽部肿瘤和内部的血管模型。然后把 CT 数据进行分割,并重建鼻咽部及 内部血管模型,最后将两个模型进行配准融合,构建鼻咽部疾病复合三维虚拟模型。并由肿瘤内科放疗组和耳鼻咽喉科的 15 名医生分别对模型进行评分。结果:制作出高逼真度、等比例的鼻咽部三维虚拟模型,并针对该模型进行问卷调查,问 卷得分均> 4 分。结论:采用鼻咽部 CT 及 MRI 图像融合方法,应用 3D 造型技术制作的三维虚拟模型,对肿瘤内科和耳 鼻喉科医师进行鼻咽部解剖、疾病认识、放疗靶区勾画应用、医患沟通以及临床实践教学等方面都有重要实际应用意义。

    Abstract:

    〔Abstract〕 Objective Based on the 3D modeling technology of nasopharynx computed tomography (CT) and magnetic resonance imaging (MRI) image fusion, the three-dimensional virtual model of nasopharynx was made, and its significance in clinical practice teaching mode and clinical work was discussed. Methods Firstly, three patients with nasopharyngeal carcinoma were scanned with MRI to obtain DICOM data, and the tumor and internal blood vessel models were segmented and reconstructed by medical influence technology. Then the CT data are segmented, and the nasopharynx and internal vascular models are reconstructed. Finally, the two models are registered and fused to build a composite three-dimensional virtual model of nasopharynx disease. The model was scored by 15 doctors from the Department of oncology and otolaryngology. Results The three-dimensional virtual model of nasopharynx with high fidelity and equal proportion was made, and a questionnaire survey was conducted on the model, and the score of the questionnaire was more than 4. Conclusion Using the fusion method of CT and MRI images of nasopharynx, the three-dimensional virtual model made by 3D modeling technology has important practical significance for oncologists and otolaryngologists in the aspects of nasopharynx anatomy, disease understanding, application of radiotherapy target delineation, doctor-patient communication and clinical training.
