1. A therapeutic treatment which applies ionizing radiation (making particles that are electrically charged, positive or negative) to any part of the body in which the temperature has been raised by artificial means.

Thermoradiography is done in an attempt to increase the radiosensitivity (sensitivity, as of the skin, tumor tissue, etc., to radiant energy; such as, x-rays or other radiations) of the body part being treated.

2. A method of treatment that combines the use of ionizing radiation and heat.

It is based on the hypothesis that heat increases the radiosensitivity of tissues.
