python - 按患者 ID 和日期进行的 C-FIND 研究

Question

我想从 PACS 下载与指定患者 ID 和研究日期相匹配的胸部 X 射线文件。
如果我在 C-FIND-Request 中指定日期，则无法获得任何匹配的结果。
你能建议我的查询有什么问题吗？
非常感谢~

我使用 pynetdicom 与 GE 的 PACS 进行交互。

PACS 中的示例记录是:
研究日期 模态 患者 ID 在线
-------------------------------------------------- -----
2021/08/21 XA 12345678 Y
2021/08/19 美国 12345678 Y
2021/08/11 美国 12345678 Y
2021/08/09 美国 12345678 Y
2021/08/02 美国 12345678 Y
2021/07/16 CR 12345678 Y
2021/08/02至2021/08/21的记录为相关研究。
我的目标是 2021/07/16 拍摄的那个。

以C-ECHO开始，然后发送C-FIND，低优先级
我试过了
(1) 患者根下的 C-FIND，患者级别
(2) C-FIND 研究根、研究级别
如果我指定日期(StudyDate = "20210716")，我将无法获得任何匹配的结果。

以下是患者根、患者级别下 C-FIND 的 pynetdicom 日志。

(1) 案例:仅以患者 ID 为条件

Answer 1

(2) C-FIND under study root, study level

I: (0008,0020) DA [20210716]                               # 1 StudyDate
I: (0008,0052) CS [PATIENT]                                # 1 QueryRetrieveLevel
I: (0010,0020) LO [12345678]                               # 1 PatientID

这是一个格式错误的请求。这不是学习级别(这很明显)。如果 Q/R Level 是 PATIENT，您只能查询 Patient-Level 键。尝试这个:

(0008,0020) DA [20210716]                               # 1 StudyDate
(0008,0052) CS [STUDY]                                # 1 QueryRetrieveLevel
(0010,0020) LO [12345678]                               # 1 PatientID
(0020,000d) UI []                                       # 1 StudyInstanceUID

这将为您提供属于患者 ID 12345678 且符合标准“研究日期 = 2021-07-16”的研究的研究实例 UID 列表。您可以从 STUDY 级别(而不是其他级别!)添加其他空属性以获得有用的附加信息(例如，研究描述、推荐医师、研究中的模式等)
