title: [A technique of continuous medical image digital restoration].
abstract: OBJECTIVE
  To set up a new technique of continuous medical image digital restoration for electronic record management.
  
  
  METHODS
  According to Freeman's chain-code principle, 92 fetal cardiotocography were scanned, thinned, trailed, and chain-coded by computer system.
  
  
  RESULTS
  92 paper-recorded cardiotocography, were transformed to digital data and saved by computer, 23 parameters were produced, which could be used in further study.
  
  
  CONCLUSIONS
  Capacity of a restoring instrument can be greatly saved since the using of digitalized restoration, so that more useful data can be stored in doctor's workstation. Digitalized data can be much easier used in electronic record management, for convenient studies research.
