Additive manufacturing (AM), formerly known as rapid prototyping, is steadily shifting its focus from industrial prototyping to medical applications as AM processes, bioadaptive materials, and medical imaging technologies develop, and the benefits of the techniques gain wider knowledge among clinicians. This article gives an overview of the main requirements for medical imaging affected by needs of AM, as well as provides a brief literature review from existing clinical cases concentrating especially on the kind of radiology they required. As an example application, a pair of CT images of the facial skull base was turned into 3D models in order to illustrate the significance of suitable imaging parameters. Additionally, the model was printed into a preoperative medical model with a popular AM device. Successful clinical cases of AM are recognized to rely heavily on efficient collaboration between various disciplines - notably operating surgeons, radiologists, and engineers. The single main requirement separating tangible model creation from traditional imaging objectives such as diagnostics and preoperative planning is the increased need for anatomical accuracy in all three spatial dimensions, but depending on the application, other specific requirements may be present as well. This article essentially intends to narrow the potential communication gap between radiologists and engineers who work with projects involving AM by showcasing the overlap between the two disciplines.
增材制造(AM),原称快速成型,随着增材制造工艺、生物适应性材料和医学成像技术的发展,以及这些技术的优势在临床医生中得到更广泛的了解,其重点正稳步从工业原型制作转向医学应用。本文概述了受增材制造需求影响的医学成像的主要要求,并对现有临床病例进行了简要文献综述,特别关注它们所需的放射学类型。作为一个示例应用,将一对面部颅底的CT图像转换为3D模型,以说明合适成像参数的重要性。此外,使用一种流行的增材制造设备将该模型打印成术前医学模型。人们认识到,增材制造的成功临床病例在很大程度上依赖于各学科之间的有效协作——特别是外科手术医生、放射科医生和工程师。将实体模型创建与诊断和术前规划等传统成像目标区分开来的唯一主要要求是,在所有三个空间维度上对解剖学准确性的需求增加,但根据应用情况,可能还存在其他特定要求。本文主要旨在通过展示这两个学科之间的重叠部分,缩小参与增材制造项目的放射科医生和工程师之间潜在的沟通差距。
