First of all we have to know that collimator is used to guide the radiation and for safe practice in dangerous Radiography. collimators are made up of high density metals eg. tungsten and heavy alloys to absorb the non required ionising radiation for safety. I think so there is no any change in beam spread when using collimators, rather than as usual.
