Existing equipment at Cambridge University's veterinary school hospital was bought second-hand from the NHS more than two decades ago.
It has been used to help treat more than 5,000 pets, but has now reached the end of its life.
A purpose-built radiotherapy centre has now been set up at the hospital.
Malcolm Brearley, of the school hospital, said the new equipment used the latest technology which will help them identify and reduce tumours in many animals and pets.
