At least one lighting circuit 210 with one or more LEDs is positioned within the ventilation channel 216 and is configured to illuminate the entire length of the bore 104. Air supplied from the ventilation channel 216 cools the lighting circuit 210 and prevents overheating effects within the lighting circuit that are caused by fields 10 generated during the medical imaging process. The lighting circuit 210 comprises one or more filters, wherein the resonance frequency of the medical imaging device is within the stopband of the filters.
