DICOM 的 支援 AWS HealthImaging

AWS HealthImaging 支援特定DICOM元素和傳輸語法。熟悉支援的病患、檢查和序列層級DICOM資料元素,因為 HealthImaging 中繼資料金鑰是以這些元素為基礎。開始匯入之前,請確認您的醫學影像資料符合 HealthImaging支援的傳輸語法和DICOM元素限制。

注意

AWS HealthImaging 目前不支援二進位分段影像或圖示影像序列像素資料。

支援的SOP類別

透過 AWS HealthImaging,您可以匯入以任何SOP類別 編碼的 DICOM P10 Service-Object 對 (SOP) 執行個體UID,包括淘汰私有 。所有私有屬性也會保留。

中繼資料標準化

當您將 DICOM P10 資料匯入 時AWS HealthImaging,資料會轉換為包含中繼資料和影像影格 (像素資料) 的影像。在轉換過程中, HealthImaging 中繼資料金鑰是根據DICOM標準的特定版本產生。 HealthImaging 目前會根據 DICOM PS3.6 2022b 資料字典 產生和支援中繼資料金鑰。

AWS HealthImaging 在病患、檢查和序列層級支援下列DICOM資料元素。

注意
