Abstract |
: |
Cancer is a major public health issue that must be addressed at an early stage; it is the leading cause of death. With early cancer detection and treatment, the survival rate can reach 97 percent, highlighting the critical need for a dependable and highly efficient method of early tumor detection. Among other techniques, an ultra-wideband (UWB) based microwave imaging system that uses microwave radiation with a frequency spectrum ranging from 3.1 to 10.6 GHz has emerged as a promising candidate. Microwave imaging system has the advantages of low cost, high-data rate, low complexity, low spectral power density, high precision range, and non-invasive. With the recent advances in both hardware and software, microwave imaging technique has gained much interest due to its low cost and non-ionizing characteristics. In this research, an effective system for microwave imaging of breast tumor detection using modified 16-printed log periodic antenna (PLPA) array is presented. The modified PLPA operates in the band from 2 to 5 GHz with stable directional patterns in the end-fire direction. Once the results of a single antenna element have been validated, the design is extended to include 16 antenna elements. The antenna in the imaging system will be used as a sensor to send and receive microwave signals to the human body. To make the use of this principle and apply it to a practical microwave imaging system for detecting tumors, the prototyped antenna can be used to send an UWB pulse to the suspected area of target phantom. The signals reflected through backscattering are picked by the prototyped antenna and then analyzed using a suitable computing system to detect if there is a tumor. The electromagnetic simulators CST and HFSS are used to design the system, while MATLAB is used to process the data. Due to the features of non-ionizing, less expensive and no side effect, the proposed imaging technique can frequently be used to detect tumors in human body. |
