A Fuzzy Logic Approach to Transcranial Sonography System with Placement Free

In transcranial sonography system, we usually placed the sensor to anterior and superior of the attachment of the upper ear (posterior temporal window). Due to this limitation, we cannot obtain transcranial information from arbitrary place of the skull. Although this limitation free system is strongly required in clinical treatment, there is no discussion of the placement free transcranial sonography system. This paper describes a new transcranial system without this limitation of the placement. We did the experiment for investigating to identify the tissue under the artificial bone, which assumes the skull and cerebral hemisphere. In it, we employ a fuzzy inference technique to achieve high identification robustness. This system is available for radiation free bedside technique, emergency usage, and non-invasive usage for diagnosing brain diseases.
