How does the size of the input and output phosphors influence the field of view in X-ray image intensifiers?

The size of the input and output phosphors directly affects the field of view (FOV) in X-ray image intensifiers.

1. Input Phosphor Size: A larger input phosphor captures a broader area of the patient’s anatomy exposed to X-rays. Consequently, a larger input phosphor leads to a larger FOV, allowing for a wider range of anatomy to be visualized in the resulting image.

2. Output Phosphor Size: The output phosphor converts the intensified X-ray image into visible light for viewing. A larger output phosphor results in magnification of the image, effectively reducing the FOV but increasing image detail. Conversely, a smaller output phosphor leads to a wider FOV but lower image resolution.

In summary, larger input phosphors increase the FOV, while larger output phosphors decrease the FOV but enhance image detail. Adjustments in phosphor sizes allow radiologists to balance FOV and image resolution based on the specific diagnostic requirements of each imaging procedure. We are a manufacturer of X-ray machines and their accessories.
