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
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) 的影像集。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
AWS HealthImaging 在病患、檢查和序列層級支援下列DICOM資料元素。
注意
如需每個患者層級元素的詳細說明,請參閱DICOM資料元素的登錄檔

支援的傳輸語法
AWS HealthImaging 支援匯入具有不同傳輸語法的 DICOM P10 檔案。有些檔案會在匯入期間保留原始傳輸語法編碼,而其他檔案則預設為無HTJ2K失真。下列範例顯示如何在 傳回的中繼資料中 HealthImaging 記錄每個執行個體StoredTransferSyntaxUID
的 GetImageSetMetadata。
"Instances": { "999.999.2.19941105.134500.2.101": { "StoredTransferSyntaxUID": "1.2.840.10008.1.2.4.50", "ImageFrames": [{ ...
注意
檢視下表時,請記住這些要點:
-
以星號 (*) 標記的傳輸語法UID項目表示檔案在匯入期間以原始編碼格式儲存。對於這些檔案,
StoredTransferSyntaxUID
位於執行個體中繼資料中的 符合原始傳輸語法。 -
沒有星號標記的傳輸語法UID項目表示檔案在匯入期間轉碼為無HTJ2K失真,並儲存在 中 HealthImaging。對於這些檔案,
StoredTransferSyntaxUID
位於執行個體中繼資料中的 是具有 RPCL Options Image Compression—Lossless Only JPEG (1.2.840.10008.1.2.4.202) 的 High-Throughput 2000。 -
如果
StoredTransferSyntaxUID
金鑰不存在或設定為null
,您可以假設其編碼為無HTJ2K失真 RPCL(1.2.840.10008.1.2.4.202)。
