One or more light beam endowed with photonic orbital angular momentum generating devices (18) are mounted at preselected locations on an insertable instrument (14) to hyperpolarize nuclear magnetic dipoles in a region of interest (80). The hyperpolarized nuclear magnetic dipoles are caused to resonate, generating magnetic resonance signals. A controller (42) 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 position. A frequency-to-position decoder (48) converts the resonance signal frequencies into spatial positions. A video processor (50) combines the spatial positions and a portion of a diagnostic image from a diagnostic image memory (54) into a combined display 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 (52).
