胶片集中打印中提高信息识别率的分析与策略

Analysis and strategy of information recognition rate improving in PACS centralized printing

目的探寻医学影像存储与传输系统（PACS）集中打印中提升胶片信息识别率的有效方法。方法分析各成像设备胶片布局中四角信息布局对识别率的影响因素；针对不同的影响因素，通过修改设备的四角信息格式、调整胶片格式、优化选片布局、修改放射信息系统存取号（RISACCESSIONNUMBER）、引入正则表达式的正确性校验以及多次识别等优化方法识别胶片信息。结果应用此方法对普放检查集中打印系统进行测试，在信息识别的准确性和有效性方面得到了显著的改进。结论信息识别优化方法提高了胶片的信息识别率，为数字影像和通信标准（DICOM）电子胶片集中打印模式的实施提供了关键技术保障。

Objective To explore the effective approaches in information recognition rate improving for picture archiving and communication system （PACS） centralized printing system. Methods Possible factors that impact information recognition rate wereanalyzed, and then proposed the relevant optimizing solutions respectively by configuring the modality printing parameters and adjusting the radiology information system accession number （RIS ACCESSION NUMBER） matching rules. Results Effectiveness and accuracy were enhanced significantly through testing at Central Printing System by using these approaches. Conclusion These methods improve effectively the film information recognition rate and provide important technical support for digital imaging and communications in medicine （DICOM） centralized printing system.
