Rx for Martian

Martin can make it back to Mars since Mars has deviated from its regular orbit temporarily and is thus closer to Earth than usual, but there is only a 10 hour window of opportunity. On the eve of his takeoff, Martin suffers a bad fall and ends up in the hospital. With only a 10-hour window at his disposal, Martin must gain a quick discharge, but can only do so if he agrees to submit to a fluoroscope--which of course would instantly reveal his true Martian identity!
