Capacity limit for DICOM transfer

Return to Summary > Data Transfer Error Handling

---

Both transfer to an external HDD and network transfer are usually done in [Enhanced_DICOM format^*1].

*1 This format combines multiple image frames into a single DICOM file. Common information (patient information, imaging conditions, etc.) can be stored only once, and different image data can be stored for each frame.

However, if the number of images in the selected series exceeds 16,384, a message will appear saying that the transfer will be switched to [Classic DICOM format^*2].

*2 Each image frame is stored as a separate DICOM instance.

Solution 1: Transfer in Classic DICOM format

“Proceed” in response to the message

---

Solution 2. Export as NIfTI file
Disk Files > File Export
Select “Non Dicom Export”.
Select “XML-REC” and “NIfTI”

“Proceed”


The default file name is “DBIEX”.

“Use Scan Name”
is selected, the file name will be the one specified on the Exam card.

Transfer Result
Classic DICOM transfer
The “DICOM” folder contained the following three types of data
7 folders (2048 x 7 = 14,336) containing 2048 records (IM_0001 to IM_2048): 00000001 to 00000007
2048 records (IM_0001 to IM_2048) outside the above folders
578 items (IM_0001 to IM_0576 and XX_0577 and XX_0578)

Export as NIfTI file
