Abstract

The present study, which is a part of a series of comparative studies, aims to find out the type of techniques for tumor detection. The tumor detection usually used is mammography, where is it being quite sensitive to the lesions in the breast by compressing the breast on X-ray image. But it still due to exposure to ionizing radiation with the way of diagnoses method by breast compression and furthermore mammography is not sensitivity for early-stage tumor detection but only for the best and effective medical treatment. So the engineers and scientists are motivated to make improvement in alternative or complementary technologies for breast imaging techniques which technique is can promise the procedure is safe, simple to perform, reasonable cost, existing convenience, sensitive to the tumors and methods of screening for breast cancer has been established namely, ultrasound, mammography and magnetic resonance imaging (MRI). More important is comfortable to patients. The result of analysis from the engineers and scientists found and propose microwave imaging is the best method for breast cancer detection and they had proven their experiment. In addition, their upgrade this method to become more sensitive which is can detect early-stage breast cancer namely microwave imaging via space-time (MIST) beam forming. To optimize measurement moderate endogenous dielectric contrast between normal and malignant tissues and increase the spatial resolution at microwave frequencies is more challenging.
