Non-invasive 3-D intracranial thermography system |
摘要 |
<p>A microwave thermography apparatus to measure temperatures within a dielectric body (30) comprises a partial ellipsoidal cavity (1) with an electrical conductive surface wherein the body (30) can be located at one focus (F1) of the cavity (1). A microwave antenna (32) located at a second focus (F2) of the cavity (1) is connected to a radiometer (36). That radiometer (36) amplifies and filters signals from the antenna (32) before they are applied to a detector (18) with the temperature of the body (30) being determined from the voltage amplitude of the detected signals. <IMAGE></p> |
