US 2019/0195487 A1 · LIGHT CIRCUIT FOR IMAGING DEVICE

Abstract

A medical imaging device having a bore 104 for receiving a patient during a medical imaging process and a ventilation channel 216 having an opening within the upper circumference of the bore for supplying cool air into the bore. 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 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.

Dependent claims

A medical imaging device for imaging a patient during a medical imaging process, the medical imaging device comprising:

a housing including:
a bore extending in a lateral direction between a proximal end and a distal end, wherein the bore is configured to accommodate at least a portion of the patient extending in the lateral direction during the medical imaging process, wherein a cross-section of the bore has a circumference;
and
an imager configured to generate images of the patient as the patient extends in the lateral direction within the bore;
a ventilation channel having an opening within the bore, wherein the opening extends around at least a portion of the bore circumference;
and
at least one lighting circuit, positioned within the ventilation channel, and configured to illuminate the bore, wherein the ventilation channel is configured to allow air to pass through the ventilation channel and over the at least one lighting circuit.
