Image Enhancement by Microwave Double Irradiation for Early Diagnosis of Breast Carcinoma

Punal M. Arabi, S. Muttan and T.V. Padmavathy

Abstract:
Cancer is the uncontrolled growth of abnormal cells; if not detected and treated at the early stage cancer would become fatal. Early detection of the disease increases the survival rate. Though there are several diagnostic methods, each method is having its own merits and demerits. In this study, a method of obtaining an active thermo gram by irradiating the patient’s breast twice using a microwave source of 2450 MHz and allowing them to cool naturally after every radiation is proposed. Results of the experiments conducted using phantom models show the temperature difference between the cancerous and normal breast tissues is increased by the first irradiation considerably; the second irradiation further elevated the temperature difference between the normal and breast tissues. Results obtained show that double irradiation technique produces a temperature difference of about 6°C between the normal and cancerous breast tissues for a cancer tumor which produces a temperature difference of 1°C between normal and cancerous tissues by passive radiation. Hence, there is a marked intensity variation between the normal and cancerous tissues of the breast in thermogram which makes the early diagnosis of breast carcinoma possible. A thermogram of normal breast is taken as a base line image to simulate the images that would be produced by the proposed method; MATLAB7.1 is used for simulating 38, 41 and 43.75°C thermal images. Thermal images for 37, 38, 39 and 43.75°C were taken using Thermal image (FLIR system-Model FLIR i5-Sweden).
