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.
