You Need the Speed

TheĀ  major advantage of digital x-rays is the speed of acquisition. Once the sensor is exposed the image is produced within seconds. This of course saves the time of going to the processor, opening the film packs waiting for the chemical processing then labeling and mounting the films. However there is another advantage to fast image acquisition which is rarely appreciated. The operator does not need to remove the sensor in order to see the image.

This creates a tremendous clinical advantage. For example if the doctor takes an x-ray and inadvertently misses the apex, he or she will see the error within seconds. The tube head or sensor (which has not moved) can be re-arranged as needed and another image taken immediately. In this way the operator can insure that hard to see structures can be captured for proper diagnosis.

With a film pack or a phosphor storage system the film or plate must leave the mouth and be processed. The operator will not see the image for several minutes. If there is an error the operator will need to re-position the tube and film with no physical reference point to return to to improve the image.

Having read this I thought it was very informative. I appreciate you taking the time and effort to put this article together. I once again find myself spending way to much time both reading and commenting. But so what, it was still worth it!
