Properties
This will transfer the raw data of an image, if the image was stored as
RawDICOM. Checkmark this when transferring to a service that can
interpret GE-proprietary raw image data, such as Centricity. If it is
checked when sending to a service that does not support GE raw data,
the service may accept the image but ignore the raw data, or may not
accept the image.
NOTE: The LOGIQ E9 stores raw data in a DICOM private tag in an image
file. A PACS may delete all private tags, or it may leave them intact, or it
may allow configuration in this regard. Keep this in mind if you later want
to retrieve raw data images from the service.
Enhanced DICOM objects shall only be transferred if this option is
checked. Default state should be unchecked.
This compresses still image files prior to sending them to the service.
This compresses loops /enhanced DICOM files prior to sending them to
the service.
This compresses image files prior to sending them to the service.
Compression takes time, but saves time when the image is transferred.
Also, storage space on the service is reduced with compression. Set the
compression type to one the service accepts.
No compression occurs.
Run-length Encoding – compression that does not lose any data that will
degrade image quality (so-called "lossless" compression).
Joint Photographic Experts Group – compression that provides both
lossless and lossy (image quality degradation) settings. Select this and a
"Quality %" field appears, in which you can select "lossless" or various
numeric settings; the higher the setting, the less image data is
compressed (bigger image file) and the less image quality is degraded.
Improved version of JPEG that, compared to JPEG, maintains the same
image quality in a smaller image file, or provides better image quality in a
file of the same size.
