Я хотел бы загрузить файлы rdsr DICOM, хранящиеся в PACS.
Сначала я запускаю ассоциацию C-FIND, чтобы получить UID экземпляра исследования. Как только UID моего экземпляра исследования появится в списке, я хочу загрузить файлы RDSR на свой локальный компьютер.
Мне не удалось для этого использовать метод C-GET.< /p>
Вот мой код:
Код: Выделить всё
## C-FIND
ds = Dataset()
ds.QueryRetrieveLevel = 'STUDY'
ds.StudyDate = '20240308'
ds.Modality = 'SR'
ds.StudyInstanceUID = ''
ae = AE(ae_title="MYPC")
ae.add_requested_context(StudyRootQueryRetrieveInformationModelFind)
assoc = ae.associate("10.258.25.9", 107, ae_title="PACS")
StudyInstanceUID_List = []
if assoc.is_established:
responses = assoc.send_c_find(ds, StudyRootQueryRetrieveInformationModelFind)
for (status, identifier) in responses:
if status:
#print('C-FIND query status: 0x{0:04X}'.format(status.Status))
if identifier:
#print('Dataset retourné par la requête C-FIND :')
StudyID = identifier.get("StudyInstanceUID")
StudyInstanceUID_List.append(StudyID)
print(StudyID)
print(identifier)
else:
pass
else:
print('Fail, Status Code: 0x{0:04X}'.format(status.Status))
assoc.release()
else:
print('Connexion Failed')
## C-GET
def handle_get(event):
"""Handle a C-GET request event."""
ds = event.identifier
return 0x0000
handlers = [(evt.EVT_C_GET, handle_get)]
ae = AE(ae_title="MYPC")
ae.add_requested_context(StudyRootQueryRetrieveInformationModelGet)
assoc = ae.associate("10.258.25.9", 107, ae_title="PACS", evt_handlers=handlers)
if assoc.is_established:
ds = Dataset()
ds.QueryRetrieveLevel = 'STUDY'
ds.StudyInstanceUID = StudyInstanceUID_List[0] # Test for the first StudyInstanceUID
ds.Modality = 'SR'
responses = assoc.send_c_get(ds, StudyRootQueryRetrieveInformationModelGet)
for (status, identifier) in responses:
if status:
print('C-GET query status: 0x{0:04x}'.format(status.Status))
else:
print('Connection timed out, was aborted or received invalid response')
# Release the association
assoc.release()
else:
print('Association rejected, aborted or never connected')
Чтобы выполнить мой первый запрос, вот журналы отладки для части C-GET:
