Abstract :
A scanning microwave thermograph has been built, operating in the band 9¿¿10 GHz, which produces a video display of the variations in the emission temperature of the human body. Image processing is incorporated in the instrument to reduce the effects of noise and antenna smoothing and also to assist in image analysis. Preliminary medical studies on a number of patients suffering from occlusive vascular disease of the lower limbs have shown that the instrument both confirms medical diagnosis made by conventional techniques and improves assessment of tissue blood flow. The technique is fast, noninvasive and passive. The instrument is selfcontained and can be used wherever convenient in clinics.
