What does a portable fluoroscopy system (C-arm) not require?

A portable fluoroscopy system, commonly known as a C-arm, does not inherently require protective curtains or drapes because of its design and the context in which it is typically used. Unlike fixed fluoroscopy systems, which may have bay doors or specific physical barriers to contain radiation and protect personnel, a C-arm is often used in a variety of settings, including surgical suites where space is limited and mobility is essential.

The primary protective barrier is still necessary in areas where the amount of radiation exposure is a concern, as it helps shield personnel and patients from scatter radiation. A dead-man type exposure switch is crucial for safety, ensuring that the X-ray exposure only occurs when the operator is actively engaged. Additionally, interlocking systems between the image intensifier and fluoroscopic tube are important for operational safety to prevent exposure when the system is not properly aligned or in use.

Thus, while the C-arm does indeed use other forms of radiation safety features, it relies less on curtains or drapes due to its operational flexibility and the environments in which it is commonly deployed.
