Modern fluoroscopy systems that utilize digital detectors typically have a readout speed of 30 frames per second (fps). This frame rate is sufficient to provide smooth and continuous imaging, essential for real-time visualization of dynamic physiological processes. The 30 fps standard allows for adequate temporal resolution for many fluoroscopic procedures while balancing the need for sufficient image quality and reduced radiation dose to the patient.

While it's true that other options, such as 60 fps or even higher rates, are used in certain specific applications or advanced systems for tasks requiring more rapid imaging, 30 fps remains the commonly achieved rate across a broad range of standard applications in clinical settings. This frame rate effectively captures the motion necessary for diagnostic or interventional purposes without overwhelming the system with excessive data or increasing radiation doses unduly. Thus, 30 fps serves as a balance between performance and safety in modern digital fluoroscopy.
