Optimalization of development process in connection with a change of a supplier of material
VORÁČ, Michal
The development process, and in fact the entire question of processing X-ray images is still, despite all of the simplifications and standardizations, a relatively complex series of interesting processes. Even though it no longer enjoys the attention it once did, its position within the diagnostic algorithm is nonetheless permanent, and until digitalization becomes practical, irreplaceable. It will continue to fall within the competence of the radiological assistant, and hence the radiological assistant will continue to hold responsibility for its optimal course. Today, of course, it is no longer to have specific chemical training, but on the other hand it is more necessary than before to ensure a responsible approach, careful work, and to a great extent a degree of enthusiasm for the entire procedure. The present work is not intended in any way to influence the choice of a new subcontract for our section, but merely to draw attention to the positive and negative aspects of this change. A series of densitometric measurements were performed under various conditions of the development process, for the purpose of investigating the advantages and disadvantages of the new film material and its results were then compared with the similarly processed values acquired under the present state of the processing procedure. The development process may be influenced by many factors; hence the complex reaction must be carefully followed and maintained within precisely delineated standards. Only as such it is possible to achieve a quality image. Even the very best photographic operation can come to naught if the final processing of the image is not correct. In this instance, the patient is quite unnecessarily subjected to a higher dose of radiation than should be, and the image does not contain all of the possible details and the diagnostic potential is lowered. Only a correctly performed development process can make the maximum use of the X-ray image and thus provide the doctor with better conditions for his or her responsible work.
