Final answer:
The radiographer should clean the x-ray table, change the pillowcase, and assemble the accessories needed for the examination before bringing a patient into the radiographic room. Warming the x-ray tube anode is not a routine part of patient preparation. External shielding and fast films also play a role in reducing radiation exposure.
Step-by-step explanation:
Before bringing a patient into the radiographic room, the radiographer should clean the x-ray table and change the pillowcase, assemble the accessories needed for the examination, and warm the x-ray tube anode. However, the standard radiographic procedure doesn't necessarily include warming up the x-ray tube anode as a part of the routine patient preparation. The anode warming is a technical preparation more related to ensuring the equipment is ready for optimal functioning. Therefore, the correct answer to the steps a radiographer should perform before bringing a patient into the radiographic room is to clean the x-ray table and change the pillowcase (to ensure hygiene and reduce the risk of infection), and assemble the accessories needed for the examination (to facilitate a smooth and efficient imaging process).
The practice of wearing a lead apron and utilizing appropriate shielding is crucial to protect both the patient and the technician from unnecessary radiation exposure. These measures, along with the use of fast films that limit the time needed to obtain images, have helped to reduce radiation doses in medical diagnostics.
