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 |
- NEMA-1 was introduced in 1985.
- NEMA-2 was introduced in 1989.
- DICOM was introduced in 1993.
