-
- The ACR-NEMA standard was created to provide a standard way of shipping
- medical images between different manufacturers equipment. It covers
- CT, MR, ultrasound, PET images, etc. Currently it supports sequences
- of 2D images, but not 3D images.
-
- The standard specifies everything from the connector to be used,
- to the communications protocol, to the contents of data fields
- in the images. You can, of course, read the data without worrying
- about the hardware or network protocols, if you get someone to ship
- you an image on tape, disk, etc.
-
- Most of the data (in terms of number of fields, not number of bits)
- has to do with how the image was aquired, who the patient is, relationship
- between images, etc). The image data per se is relatively primitive
- (bit map, no compression). The intent was to make it simple and standard,
- rather than technically sophisticated.
-
- The standard is ACR-NEMA Standards Publication No 300-1988. Note the "1988".
- This is the second version of the standard (published in 1989, of course :-)
-
- It is published by
-
- National Electrical Manufacturers Association
- 2101 L Streeet, N.W.
- Washington, DC 20037
- USA
-
- Afraid I don't know the price.

- Look in:
- -- ACR-NEMA Standard Publication for Digital Imaging and
- Communications. Washington, DC, NEMA Publication no. 300, 1985.
-
- this is the complete description of the standard, how to transmit an
- image across an interface. It also describes the "commmon image data
- format" which required... for a short description see:
-
- -- Chris Spilker, The ACR-NEMA Digital Imaging and Communications Standard:
- A Nontechnical Description. Journal of Digital Imaging, Vol 2,
- No. 3 (August), 1988:pp 127-131.

- hope this helps....
