目前，各机构对成像程序的命名尚未标准化。因此，建立国家登记是一项挑战，例如，建立国家剂量登记以促进不同类型CT程序之间的比较。RSNA的RadLex Playbook致力于解决这一差距（通过为每个过程引入一个称为RPID的唯一Playbook标识符），目前的研究重点是将机构特定的过程描述半自动地映射到Playbook条目，以协助这种标准化工作。我们讨论了我们开发的一种算法，以促进映射过程，该算法首先从过程描述中提取RadLex代码，然后使用RPID的定义来确定提取的RadLex代码集最合适的RPID。我们还开发了一个工具，它具有三种操作模式——单个过程映射模式，允许用户将单个机构特定的过程描述映射到Playbook条目；批量模式，用于处理大量描述；探索模式，帮助用户更好地理解各种Playbook属性值的选择如何影响最终的RPID。我们使用166个生产CT过程描述验证了我们的算法，并讨论了管理员如何使用该工具将机构特定的过程描述映射到rpid。
The naming of imaging procedures is currently not standardized across institutions. As a result, it is a challenge to establish national registries, for instance, a national registry of dose to facilitate comparisons among different types of CT procedures. RSNA's RadLex Playbook is an effort towards addressing this gap (by introducing a unique Playbook identifier called an RPID for each procedure), and the current research focuses on semi-automatically mapping institution-specific procedure descriptions to Playbook entries to assist with this standardization effort. We discuss an algorithm we have developed to facilitate the mapping process which first extracts RadLex codes from the procedure description and then uses the definition of an RPID to determine the most suitable RPID(s) for the extracted set of RadLex codes. We also developed a tool that has three modes of operations-a single procedure mapping mode that allows a user to map a single institution-specific procedure description to a Playbook entry, a bulk mode to process large number of descriptions, and an exploratory mode that assists a user to better understand how the selection of values for various Playbook attributes affects the resulting RPID. We validate our algorithms using 166 production CT procedure descriptions and discuss how the tool can be used by administrators to map institution-specific procedure descriptions to RPIDs.
