Can a radiologist deliberately give you cancer by x-ray or ct device. is their a dose or number of photos limit in a given time in these equipments?

Can't happen: The dosage on these things is limited. You'd be aware of being imaged for an excessively (ridiculously) long time. And you'd get radiation sickness or a radiation burn at once if you were given a dose likely to cause cancer years later. "Pop" claims about medical imaging causing large numbers of cancers are based -- in my informed opinion -- on flawed assumptions. Best wishes.
