Active device tracking using light with orbital angular momentum to hyperpolarized MRI
Abstract:
One or more light beam endowed with photonic orbital angular momentum generating devices are mounted at preselected locations on an insertable instrument to hyperpolarize nuclear magnetic dipoles in a region of interest. The hyperpolarized nuclear magnetic dipoles are caused to resonate, generating magnetic resonance signals. A controller controls gradient coils to induce a magnetic field gradient across the region of interest, such that the frequency of the resonance signals is indicative of spatial positions. A frequency-to-position decoder converts the resonance signal frequencies into spatial positions. A video processor combines the spatial positions and a portion of a diagnostic image from a diagnostic image memory into a combined image which depicts the location of the region of interest or a portion of the instrument marked on the diagnostic image and displays the combined image on a monitor.
