Field of view collimation at work

Uvod: Primarni rentgenski snop omejimo z zaslonko, ki je vgrajena pod ohišje rentgenske cevi. Uporaba zaslonke je pomembna zaradi dveh stvari, in sicer zaradi zmanjšanja izpostavljenosti nepotrebnemu sevanju in zmanjšanja vpliva sipanega sevanja. Namen: Želeli smo prikazati, kako dosledno radiološki inženirji uporabljajo zaslonko in kdaj so manj pozorni oz. je ne uporabljajo in kako poznajo njen namen uporabe. Metode dela: V teoretičnem delu smo uporabili deskriptivno metodo in pregledali domačo in tujo strokovno literaturo. V praktičnem delu pa smo v času klinične prakse opazovali, kako dosledno radiološki inženirji uporabljajo zaslonko. Po koncu prakse smo še izvedli anketiranje inženirjev. Rezultati: Pri opazovanju smo ugotovili, da so radiološki inženirji v 81 % ustrezno dodatno zaslonili polje, v 15 % so pustili polje v velikosti slikovnega sprejemnika in le v 4 % so pustili polje odprto večje od velikosti slikovnega sprejemnika. Z rezultati anketnega vprašalnika smo ugotovili, da 62 % radioloških inženirjev pozna namen uporabe zaslonke, hkrati pa smo ugotovili, da moški bolje poznajo vpliv zaslonke in kdaj je zaslanjanje optimalno. Razprava in zaključek: Ugotovili smo, da radiološki inženirji v večini (81 %) dosledno uporabljajo zaslonko, da so v 69 % manj pozorni na uporabo zaslonke na urgentni diagnostiki, v 38 % pri starejših in v 31 % v naglici. Vsi inženirji pa so bolj pozorni pri slikanju otrok in manj pozorni pri slikanju starejših.Introduction: X-ray beams are limited by using a collimator which is built in underneath the housing of the x-ray pipe. Using the collimator is important for two things. It lowers the dose on the patient as well as lowers the effect of scattered radiation. Purpose: We were trying to show how often do radiologic technologists use the collimator or when they don\u27t and if they know the purpose of using it. Methods: In the theoretical part we used a descriptive method where we looked through domestic and foreign literature. Then we observed if radiologic tecnologist use a collimator at their work in a hospital. After the observaiton we included them in a survey. Results: With our observation we noticed that in 81% the radiologic technologist use the collimator accordingly, in 15% the field of collimation is left opened to the size of the detector and in 4% they left the field opened more than the size of the detector. With the survey we found out that men know more about the purpose and when the collimation is optimal than women. Discussion and conclusion: With the research we found out that most of the radiologic technologist (81%) use the collimator accordingly. That in 69% they pay less attention to the collimator in the emergency room, in 38% with the older population and in 32% when they are in a hurry. All of the radiologic technologist pay more attention to collimation when examining children and less when examining the elderly
