1. A personal warming device usable to warm a patient undergoing an x-ray examination in an x-ray field, the personal warming device comprising:

  • a patient support portion configured to support at least a portion of the patient in the x-ray field;

    a heating element positioned at least proximate to the patient support portion, the heating element configured to generate heat to warm the patient when the patient is positioned at least partially on the patient support portion;

    a temperature sensing device positioned at least proximate to the heating element, wherein the temperature sensing device is at least generally transparent to x-rays, and wherein the temperature sensing device is configured to change a characteristic of a light signal passing through it when it is heated to a predetermined temperature;

    a first fiber optic tubes operably coupled to the temperature sensing device; and

    a second fiber optic tube operably coupled to the temperature sensing device, wherein the first fiber optic tube is configured to transmit the light signal to the temperature sensing device, and wherein the second fiber optic tube is configured to transmit the light signal away from the temperature sensing device.
