<p>A dispenser is provided for producing a nuclear hyperpolarised contrast agent. The dispenser comprises a chamber to receive a compound. A photonic hyperpolarisation system generates an OAM-photonic beam endowed with orbital angular momentum and is arranged to direct the OAM-photonic beam into the chamber so as to generate nuclear hyperpolarisation in the compound. The chamber has an output over which the hyperpolarised compound can be issued. Since the hyperpolarisation is generated ex-vivo, the penetration depth of the OAM-photonic beam in biological tissue is irrelevant for the present invention.</p> |
