Supported Image Formats

Nema Family Image

NEMA family images
Format Notes
NEMA-1*
and
NEMA-2*
When converting these, DICOMatic will remove tags that are no longer supported, and make sure the images are compatible with the latest DICOM specifications
SPI This variation on NEMA-1 and NEMA-2 is used by both Siemens and Philips
IS&C This Japanese variation on NEMA-1 split the images in 2 parts: a header (.INF) and the pixel data (.IMG). In addition, the pixel data is sometimes compressed
DICOM* Why would you need to use DICOMatic to convert images from DICOM to DICOM? Over the years, some manufacturers have created images that have problems (errors in their tags or in the compression). DICOMatic will correct most of these errors. DICOMatic will also uncompress the images it converts

* Historical notes:
  • NEMA-1 was published in 1985.
  • NEMA-2 was published in 1988.
  • DICOM (parts 1 to 8) was introduced in 1991.
  • DICOM (parts 1 to 9) was approved in 1993.
  • DICOM part-10 (file format) introduced in 1994.

Analyze The images are split in 2 parts: the header (.hdr) and the pixel data (.img)
iScan Images produced by the Compurad's iScan software
Materialise  
Papyrus A variation of DICOM
RAW Usually refer to files that only have pixel data without any headers. These images can be read using the "Raw_Header" tool to create a header (.hdr) for the pixel data
JPEG JPEG images will be considered "SC" (Secondary Capture) with a modality of "OT" (Other)
TIFF TIFF images will be considered "SC" (Secondary Capture) with a modality of "OT" (Other)
Others Any file containing uncompressed pixel data can be read by using the "Raw_Header" tool to create a header (.hdr) for the pixel data. The pixel data can be 8, 16 or 32 bits, integer or float, signed or unsigned, little endian or big endian, B&W or color (3 or 4 components)
