Question

我有一个关于同伴橡木dicom的c-find操作的问题。我已经开发了一种服务，它实现了c-find操作，并且应该将找到的患者送回超声机器。我目前正在测试GE的4d视图“模拟器”。

我已经实现了我在此论坛上发现的代码并接收了请求。我发回一个数据集，但每次我在超声波机器上都会收到没有找到物品的消息。 →

愿你们中的任何人能帮助我吗？

提前致谢

您在C-FIND响应中缺少许多必需的返回键属性。请查看PS 3.4 of the DICOM standard中的“表K.6-1 - 模态工作列表信息模型的属性”。如果“返回键类型”列中的值为“1”，则必须在C-Find响应中包含具有有效值的属性。例如，预定站AE标题（0040,0001），预定过程步骤开始日期（0040,0002），预定过程步骤开始时间（0040,0003），模态（0008,0060）等是预定下的类型1返回键程序步骤顺序（0040,0100）。

如果“返回键类型”列的值为“2”，则必须在C-Find响应中包含该属性，但它可以为空（如果不知道）。此类属性的示例是计划执行医生姓名，计划工作站名称和计划过程步骤位置等。

当满足条件时，值“1C”类似于类型“1”。这样的示例是预定过程步骤描述和预定协议代码序列。而且，“2C”是有条件的类型“2”。类型“3”是可选的，如果属性不在请求数据集中，则不需要在响应中包含它们。
