Final answer:
The pixel size of a 2048 × 2048 matrix with an 80-cm FOV is 0.039 cm per pixel.
Step-by-step explanation:
The pixel size of a 2048 × 2048 matrix with an 80-cm field of view can be calculated by dividing the field of view by the number of pixels in each dimension. In this case, the FOV is 80 cm, and the matrix size is 2048 × 2048 pixels. So the pixel size can be calculated as: 80 cm / 2048 pixels = 0.039 cm per pixel.
