On the Limitation of Ultra-Wideband Technique for Medical Scanning Systems
MetadataShow full item record
In this study, the ultra-wideband (UWB) technique and its capability to detect the cells and layer of a human organs in medical scanning applications has been considered. Advantages and disadvantages of the technique has been highlighted with respect to the capability and accuracy of a medical scanning system especially those using the pulse reflected-based technique. The study contrasts the difference between advantages of using UWB techniques for medical applications, such as eliminating ionising effects, and disadvantages, mainly due to those associated with penetration depth, range resolution, and cost within the unlicensed UWB frequency range (3.1–10.6 GHz). The above disadvantageous factors can cause drawbacks which limit the application of such techniques in human tissue scanning systems for early stages diagnostics. The UWB system has been studied well for the centre frequencies of 6GHz and 4 GHz, which found to have more potential in the UWB region among the researchers, however the outcomes indicates that there was a lack of knowledge base on the limitations associated with each of these frequencies.
