C
The correct answer is (B) 1 and 2 only.
1. Positioning the image intensifier as far from the patient as possible: This method helps to decrease patient exposure by increasing the distance between the patient and the source of radiation. When the image intensifier is placed further away from the patient, the amount of radiation reaching the patient is reduced. This method is effective in reducing radiation exposure to the patient.
2. Using the last image hold feature: This feature allows the radiation technologist to pause the fluoroscopic procedure and maintain the last image on the monitor screen. This eliminates the need to continue irradiating the patient unnecessarily during image repositioning or examination. Using this feature can also reduce the amount of radiation exposure to the patient.
3. Using the smallest FOV: While a smaller FOV (field of view) can reduce the amount of radiation needed to produce an image, it may not be possible in all circumstances as it could negatively impact the quality of the image. Therefore, this method is not as effective in reducing radiation exposure as the above-mentioned methods.
Therefore, (B) 1 and 2 only are the correct methods of decreasing patient exposure during fluoroscopic procedures.
