Even so, it requires a well- established network of cyclotron facilities proficient of providing radiolabelled compounds at the sufferer bed. This chapter highlights state-of-the-art and approaching prospects of medical imaging, mostly in the feld of nuclear imaging. It focuses on new devel- opments and innovations brought nearby the nuclear physics community. Diferent sections clothe hard- ware and sofware developments in clinical and preclinical studies as marvellously as interface applications with other chapters of this booklet.
