What is another name for a "Bow-Tie" filter in X-ray systems?

In X-ray systems, the "Bow-Tie" filter is also known as a Beam Filter. This filter is specifically designed to optimize the X-ray beam profile by varying the thickness of material through which the X-ray beam passes. The unique shape of the Bow-Tie filter helps to reduce the overall dose to the patient while providing a uniform exposure across the imaging area, particularly in the context of computed tomography (CT). This design accommodates the anatomy's natural contours, allowing for improved image quality by balancing the intensity of the radiation and minimizing unnecessary exposure.

The terms used for the other choices do not capture the specific function and design characteristics of the Bow-Tie filter. While high-pass filters and energy filters are used in different contexts of signal and image processing in radiation systems, they do not serve the same purpose as a beam filter. Additionally, the term "Phase Filter" is not commonly associated with X-ray systems in this context. Thus, Beam Filter is the precise terminology that aligns with the function and application of the Bow-Tie filter in X-ray imaging.
