D
The correct answer is (B) 1 and 2 only.
1. Filtration: An x-ray machine that is designed especially to eliminate unnecessary radiation to the patient has a filtration system that absorbs low-energy photons before they reach the patient. This means that the patient receives a smaller dose of radiation and the images produced are of higher quality.
2. Minimum SSD of 30 cm: SSD stands for Source-to-Skin Distance, which refers to the distance between the x-ray tube and the patient’s skin. An x-ray machine that is designed to eliminate unnecessary radiation to the patient has a minimum SSD of 30 cm. This increases the distance between the x-ray source and the patient’s skin, reducing the amount of radiation that the patient receives.
3. Collimator accuracy: A collimator is a device on an x-ray machine that restricts the size and shape of the x-ray beam. An x-ray machine that is designed to eliminate unnecessary radiation to the patient has a collimator with high accuracy. This ensures that only the necessary areas are exposed to radiation, reducing the overall radiation dose to the patient. However, collimator accuracy is not solely responsible for eliminating unnecessary radiation to the patient, so option 3 is incorrect.
Therefore, the correct answer is (B) 1 and 2 only.
