First of all, we know that the tube voltage can directly determine the quality of the rays, that is, the higher the voltage, the harder the rays, and the more scattered rays.
So why the higher the tube voltage scatters the more rays, because the scattered rays excited by the high-energy rays are more concentrated, while the scattered rays excited by the low-energy rays are more scattered.
So what does scattering have to do with dose? Simply put, the higher the dose, the more scattered rays. The thinner the irradiated lift, the lower the dose required and the less scattered rays.
Therefore, not all cases need to use the grid, and the use of the grid should also be selected according to the actual situation.
