Как отличить КТ-изображения от двух разных производителей с помощью команд DCMTK?
Я пытаюсь получить изображения с сервера. Я заинтересован в получении КТ изображений для конкретного пациента. Я выполняю следующие команды DCMTK из командной строки (Windows):
1) Я получаю UID экземпляра исследования моего ID пациента (0020 000D)
findscu -v -aet DCMTK -aec VMSDBD 10.196.XX.XXX 51XXX -S -k PatientID=303XXXXX -k QueryRetrieveLevel=STUDY -k 0020,000D

....
2) Я получаю UID серийных экземпляров модов КТ, представленных в исследовании (0020,000E):
findscu -aet DCMTK -aec VMSDBD 10.196.XX.XXX 51XXX -S -k PatientID=3038XXXX -k QueryRetrieveLevel=SERIES -k "0020,000D=1.2.840.113619.2.278.3.346865037.482.1505267XXXX.XXX" -k "0008,0060=CT" -k 0020,000E

3) Теперь я могу просто использовать UID экземпляра серии, чтобы получить изображения CT с сервера:
movescu –aet DCMTK –aec VMSDBD -aem VMSFSD-OUT –S -k 0008,0052=SERIES -k 0020,000E=1.2.840.113619.2.278.3.346865037.388.15390421XX.XXX 10.196.XX.XXX 51XXX

I: Получен ответ на ход 1 (в ожидании)

Проблема состоит в том, что у пациентов есть два типа серии CT: "ConeBeam CT" и "CT:
Но тег Modality (0008,0060) для обоих типов серии CT - "CT". Я просто хочу вытащить серию CT "ConeBeam". С предыдущими командами я тяну все (обе). то есть я не могу отличить "ConeBeam CT" от "CT".
Итак, есть ли способ отличить серию "ConeBeam CT" от серии "CT", используя команды DCMTK?

Одним из очевидных способов достижения этого является фильтрация (в то время как C-FIND) по тегу, который различает экземпляры. Это то, что вы пытаетесь достичь. Проблема в том, что обычно используемые фильтры не включают такой тег.
Поскольку вы работаете на уровне Серии, в ответе C-FIND такого тега также нет. Я не уверен, доступен ли такой тег в ответе C-FIND уровня изображения; но даже если это так, это ненадежный способ, так как многие реализации PACS могут не вернуть его.
Так что это невозможно / надежно с помощью C-FIND.
Вы должны идти на шаг впереди.
Вы должны извлечь экземпляры (C-MOVE/C-GET) и отфильтровать их на вашем S-STORE SCP.
В этом случае вам также нужно найти тег, который отличает экземпляры. В вашем конкретном случае (0008,0070) Manufacturer и / или (0008,1090) Manufacturer's Model Name можно считать.
Конечно, это не обобщенное или стандартное решение.
