If the field of view is 10 cm and the matrix size is 200, what is the pixel size in cm?

Explanation:
Pixel size tells you how much real-world distance each pixel represents. To find it, divide the field of view by the number of pixels along one dimension. With a 10 cm field of view and a 200-pixel matrix, the calculation is 10 cm ÷ 200 = 0.05 cm per pixel, which is 0.5 mm. So the pixel size is 0.05 cm. The other numbers would require different matrix sizes: 0.5 cm would need a 20-pixel matrix across, 0.02 cm would need 500 pixels, and 0.25 cm would need 40 pixels.
