How is pixel size calculated in digital imaging?

The calculation of pixel size in digital imaging involves determining how much area each pixel occupies within the overall field of view. This is done by dividing the field of view (FOV) by the dimensions of the matrix (the array of pixels).

In this context, the field of view represents the physical area that the imaging system captures, while the matrix indicates the number of pixels that are used to form the image. By dividing the field of view by the matrix size, you derive the size of each individual pixel. This understanding is crucial because pixel size influences the resolution and overall quality of the digital image captured.

Choosing the correct method of calculating pixel size is essential for producing images with clarity and detail. The other options either describe irrelevant calculations or inaccurately integrate different components of imaging, which do not lead to a valid measure of pixel size.
