needed, which would make the system less efficient to the 
existing one. 
Replacement of the film with electronic detectors would 
eliminate the digitization phase and increase the system 
efficiency but also increase the cost. 
Attitude 
Many radiologists and physicians are resisting any attempts 
to computerize conventional X-ray images. They view it as 
an unnecessary development process and see the existing 
system as the best that can be obtained with current 
technology. 
All the above limitations will be reduced, and probably will 
become insignificant, as development of computer 
hardware and software advances. At that point, the 
negative attitude of the medical community will also be 
lessened and eventually digital X-ray would become a 
reality. 
onclusion 
Image processing techniques can be used to minimize 
- significantly the number of rejected X-rays. Enhanced 
' image contrast and visibility will help both physicians and 
radiologists make more accurate diagnosis. This in turn 
will reduce the risk of radiation exposure and increase the 
economical benefits. The enhanced X-ray images are 
sharper, more visible and recognizable, and provide more 
information.
