Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. With the increasingly widespread use of digital technology, medical X-ray imaging has been varying degrees of integration of digital technology. For Medical Terms of use X-ray image intensifier television system, with the gradual deepening of digital technology, the original evaluation of medical X-ray image intensifiers The TV system approach has changed. To make these new methods of standardization in the 2007 version of the standard was revised. Instead of the standard YY/T 0608-2007 "medical X-ray image intensifier television system General technical conditions"; Compared with YY/T 0608-2007 The main technical differences are as follows. --- Modify the description of the scope of the standard, to avoid the installation of medical X-ray image intensifier television system of medical X-ray machine Unable to cite this standard problem; --- Remove the "incident air kerma rate" requirements and test methods; --- Low contrast resolution requirements from 2% to 4.4%; --- 5.4,5.5,5.6 original terms of reference GB 19042.1-2003 changed directly describe; --- Added Appendix H test parameters, symbols and units; --- Removed YY/T 0457.4-2003 of reference. Terms of reference defined directly. Please note that some of the content of this document may involve patents. Release mechanism of the present document does not assume responsibility for the identification of these patents. This standard was proposed by the China Food and Drug Administration. This standard by the National Standardization Technical Committee medical electrical medical X-ray equipment and utensils Standardization Technical Committee (SAC/TC10/SC1) centralized.
