? ? ?這里使用的仍然是pydicom和pynetdicom模塊，在使用前需安裝。

思路：首先初始化AE作為SCP，并創(chuàng)建數(shù)據(jù)集dataset，dataset中可以設定具體tag的值，此處可根據(jù)需要自行設定。然后和服務端SCU連接，用send_c_find來查詢worklist，query_model為“W”表示"1.2.840.10008.5.1.4.31"，即?“Modality Worklist Information - FIND”。Worklist 其實就是一個 C-Find 請求，不過這個 C-Find 請求指定了 SOP Class UID 為 【1.2.840.10008.5.1.4.31】。
