What is the purpose of an aluminum filter?

  1. Enhance image contrast

  2. Eliminate scatter radiation

  3. To filter out the low and long energy rays

  4. Control exposure time

The correct answer is: To filter out the low and long energy rays

An aluminum filter is specifically designed to filter out the low and long energy rays in order to reduce the amount of scattered radiation. This can help to improve the quality of the image as it eliminates any unwanted noise caused by these rays. Options A, B, and D do not accurately describe the purpose of an aluminum filter. Enhancing image contrast, eliminating scatter radiation, and controlling exposure time can all be achieved through other means and are not the primary purpose of an aluminum filter.
