Increasing field size affects scattered radiation in which way?

Explanation:
Expanding the field size irradiates more tissue, and scattered radiation comes from interactions inside that tissue. With a larger field, there are more potential sites for photons to scatter (primarily via Compton interactions), and those scattered photons exit in various directions, some reaching the image receptor. That means the total amount of scatter detected increases, which lowers image contrast. So, increasing field size leads to more scattered radiation.
