<p>A medical imaging apparatus for imaging subcutaneous body temperature that comprises a detector (22) for sensing millimetre wave electromagnetic radiation and a collector for collecting radiation emitted from a patient's body and directing it along a collection path (20) to the detector. The collector is configured so that the collected radiation has a defined sensitivity profile across and along substantially the entire length of that path. The collected radiation may have a Gaussian or a Bessel sensitivity profile.</p> |
