I’m writing a paper on the involvement of radiologic technologists in the placment of Deep Brain Stimulators. I’ve found quite a bit of information about the procedure from a surgical point of view and I’ve also located a patient willing to present her perspective… what I need is a complete rundown of the procedures and equipment used by the radiographers imaging during the procedure.
