Computed Radiography System Experience In Vision Diagnostic Centre

         Almost a year has passed since we upgraded our X-ray department to state-of-the-art Computed Radiography (CR) system from darkroom processor. Since then, more than 1000 patients has undergone X-ray examinations of various parts (mainly chest X-rays), and close to 100 patients has done their mammography examination here.

        Back in the days where darkroom is our only means for film processing, the maximum number of patients that we can receive a day is around 20 patients. This is because of the time taken for the film to be developed, not to mention if additional views are required or repeated examinations due to errors. Waiting time is quite long, especially when patients came in groups.
      
      However, with the installation of a completely computerized imaging solution, the time taken for an examination to finish has decreased significantly. This is because the image processing time has been reduced to mere seconds, compared to almost 3-5 minutes on darkroom processing. Hence, we are able to reduce waiting time and cater more patients, and the department can be run more efficiently. Radiation safety aspect is also improved, where we are able to implement the high kV technique which essentially reduces exposure time and amount. This results in reduced radiation dose but with images that are on par, if not superior, with diagnostic quality as done previously.

        We are also equipped with a PACS system, which facilitates film viewing for our radiologists. By using PACS, X-ray images, especially mammogram, can be viewed without printing the films. This is advantageous because a soft copy image can be manipulated for optimal contrast and details. In addition, the image can be zoomed and enlarged at the part which shows suspicious mass or nodules, a characteristic not found on conventional X-ray film.

       In a nutshell,computerized system has increased the efficiency of the X-ray department to a level that is not possible by the previous system. Moreover, reduction in patient's radiation dose is a part of our responsibility as a radiographer, thus by this CR system, we are able to fulfill that responsibility.
