A large number of file formats are supported by the Dragonfly Image Loader — standard image files, raw data, TIFF stacks, and a number of proprietary file formats. These files can be imported from local and network drives or from storage devices such as CDs, DVDs, and USB keys.
For 3D volumetric data, Dragonfly supports the following file formats:
|
Format |
Extension |
Description |
|---|---|---|
|
Image stacks |
.tif, .tiff, .jpeg, .jpg, .png, .bmp, .dib |
Sets of 2D images that will be imported together to form a volume. You should note that all files must be of the same size and type to be rendered together. |
|
TIFF |
.tif, .tiff |
This file format differs from an image stack in that the entire volume is stored in a single file. Although the majority of TIFFs contain just a single image stored in a directory, some applications can generate multi-directory TIFFs that contain multiple images. |
|
Raw data |
.raw, .pic |
A basic file format that saves the active image or stack as raw pixel data without a header. |
|
DAT |
.dat |
Header file for accompanying raw data. |
|
DICOM |
.dcm |
Digital Imaging and Communications in Medicine (DICOM) is a standard for handling, storing, printing, and transmitting information in medical imaging. It includes a file format definition and a network communications protocol. The communication protocol is an application protocol that uses TCP/IP to communicate between systems. The data stream has a so called tagged format, with a variable amount of tags (DICOM data elements). Each element is defined by a unique group-element identifier. These group element pairs are always sorted in ascending order within the DICOM data stream. See Using the DICOM Loader for information about importing DICOM studies and series. |
|
Analyze |
.hdr with accompanying .img |
Analyze 7.5 files. The Analyze file format was developed at the Mayo Clinic as part of a software package of the same name. Datasets in this format consist of small HDR files that describe the data and IMG files with the raw data. Although there are multiple versions of this format, Dragonfly only supports the 7.5 variant. |
|
MRC |
.mrc |
A file format for electron density that has become an industry standard in Cryo-electron microscopy. It was developed by the MRC (Medical Research Council) Laboratory of Molecular Biology. |
|
REK |
.rek |
Fraunhofer raw data file format. |
|
TXM |
.txm |
A file format used by ZEISS Xradia 3D X-ray Microscopes. Dragonfly Pro supports TXM files using unsigned char, unsigned short integer, or float data. Contact Object Research Systems for information about the availability of Dragonfly Pro. |
|
CZI |
.czi |
A file format used by ZEISS microscopes to save data, such as image stacks and time lapse series. Available for Dragonfly Pro only. Contact Object Research Systems for information about the availability of Dragonfly Pro. |
|
ORS object file |
.ORSObject |
Proprietary binary formatted file in which data is written sequentially and XML (Extensible Markup Language) is appended after the binary data. ORSObject files can contain multiple datasets and other objects, such as regions of interest, annotations, and meshes. |
See Image File Formats for more information about the supported files.
