Staff at St James's University Hospital in Leeds have come up with an ingenious idea to help young cancer sufferers.
A miniature version of a cancer treatment machine - which can be attached to dolls - has been made by engineers at the hospital.
Staff will use this to explain to children how their cancer treatment will work.
Controlled by a series of motors which the children can operate with buttons, a doll in a specially made hospital gown and mask is laid on the treatment couch, which moves up and down. The machine also rotates realistically around the doll.
