According to the ACR, what is the maximum entrance exposure for chest views using an ACR phantom?

The American College of Radiology (ACR) sets guidelines for maximum entrance exposure to ensure the safety of patients undergoing radiographic procedures. For chest views, the maximum entrance exposure is generally capped at 50 mR when using a standard ACR phantom. This limit is established to minimize the radiation dose to patients while still enabling effective imaging.

Maintaining this standard helps in balancing the need for high-quality diagnostic images and the principle of radiation safety. It ensures that facilities equipped with radiographic systems operate within safe exposure parameters, protecting both patients and operators from potential overexposure.
