DICOM C-GET 与 C-MOVE
我必须开发一个 SCU(服务类用户)应用程序来查询 PACS 并检索 DICOM 图像。
我应该使用 C-GET 还是 C-MOVE DICOM 协议来检索图像?

重点不仅在于安全,还在于实施。
在 C-MOVE 中,SCP 列出了与先前查询匹配的每个图像所支持的传输语法。然后 SCU 同意任何一个。
另一方面,在 C-GET 中,SCU 在进行任何查询之前列出其支持的传输语法,并且 SCP 必须选择任何一个并妥协以发送 SCU 以该格式请求的任何内容。
因此,PACS 的 C-GET 实现更加困难和复杂,因为它必须能够将任何内容编码为任何内容。而在 C-MOVE 中,客户端必须能够解码并显示任何东西,这要容易得多......
The point is not only about security, but about implementation.
In C-MOVE, the SCP list the supported transfer syntaxes for each image matching the previous query. Then the SCU agree with any.
On the other side, in the C-GET, the SCU list its supporting transfer syntaxes before any query is made, and the SCP has to pick any and compromise to send whatever the SCU ask for in that format.
So, the C-GET implementation for PACS is harder and more complex since it has to be able to encode anything to anything. While in the C-MOVE is the client who has to be able to decode and show anything which is much easier...
您可以使用其中任何一种,但首选是 C-Move。
这有两个原因。
正如@NathanWheeler 在评论中所说:
You can use either, but the preferred is C-Move.
There are two reasons for this.
