title: [Is telemammography an option for screening programs?--A phantom study].
abstract: OBJECTIVE
  To show that it is possible to proceed a 20-fold JPEG 2000 wavelet compression of radiographs of a CDMAM phantom without data loss and the usefulness of this technique in telemammography for screening.
  
  
  METHODS
  After digitizing and a 20-fold data compression, four radiographs of a CDMAM phantom were transferred via ISDN to a PACS archive. Using a soft copy work station, the contrast detail detectability of these data sets was compared to the contrast detail detectability of the original radiographs.
  
  
  RESULTS
  The contrast detail detectability showed no difference for the original radiographs and the data sets.
  
  
  CONCLUSIONS
  It is possible to digitize radiographs of a contrast detail mammography phantom, to compress the data sets, to transfer them to a soft copy station and to decompress them without negative influence on the contrast detail detectability.
