When might it not be possible to use Automatic Brightness Control (ABC) fluoroscopic equipment?

Using Automatic Brightness Control (ABC) fluoroscopic equipment can be limited under specific circumstances, particularly when working with infants. ABC is designed to adjust the radiation dose and image quality automatically based on the density and composition of the structures being imaged. However, in the case of infants, their small size and the varying density of their anatomical structures may pose challenges for the system to effectively adjust the brightness and contrast.

In addition, the anatomical features of infants may not provide enough feedback for the ABC system to function optimally, leading to potential image quality issues. This limitation is critical because accurate imaging is essential for appropriate diagnosis and treatment planning. Therefore, while ABC is a valuable tool in many scenarios, in the instance of infants, its effectiveness can be significantly compromised, necessitating alternative techniques.

Other scenarios may also present challenges for ABC, but the complexity of imaging infants is a notable factor due to their unique anatomical characteristics.
