What type of exposure switch is required for fluoroscopic systems?

In fluoroscopic systems, a dead-man type switch is essential to enhance patient and operator safety during procedures. This type of switch is designed to be activated only when the operator is continually applying pressure to it, which ensures that the radiation is emitted only while the operator is engaged with the system. This mechanism minimizes the risk of unintended radiation exposure to patients and staff, as the exposure immediately stops when the operator releases the switch.

This safety feature aligns with regulatory standards that require that fluoroscopic equipment be designed so that exposure cannot occur unless the operator is actively engaged and in control. In this way, the dead-man type switch acts as a crucial safeguard, ensuring that any lapse in attention by the operator directly results in the cessation of radiation output.
