Which of the following is NOT a technique mode available in fluoroscopy?

In fluoroscopy, technique modes typically allow for varying degrees of automatic and manual control over factors such as kilovoltage peak (kVp) and milliamperes (mA). The correct answer identifies "Manual mA only" as not being a standard technique mode.

In fluoroscopy, while operators can manually adjust parameters, the practice usually incorporates both kVp and mA in a more flexible manner, allowing for adjustments to optimize image quality and minimize patient exposure. Modes that allow for kVp variability or dual variations of both kVp and mA are widely used to adapt to different imaging scenarios and patient conditions.

Options that include both kVp and mA adjustments are relevant because they reflect the integrated approach to managing radiation exposure while still obtaining the necessary image quality for diagnosis. The idea of "Manual mA only" implies a limitation to only controlling mA, lacking the adjustments in kVp that are commonly necessary during fluoroscopic procedures to maintain image resolution and contrast. Thus, this choice does not represent a typical operational mode in fluoroscopy.
