摘要：
This invention discloses an ultrasound receiving and emitting processing system and a processing method thereof, which first generates a driving electric signal next, emitting at least one first ultrasound signal with a main frequency to a reflection position according to the electric signal an object at the position, such as local blood capillary in cerebrum will reflect the first ultrasound signal to form at least one second ultrasound signal then, extracting the signal to be analyzed having its frequency less than the main frequency from the second ultrasound signal, and stopping receiving other signals to convert the signal to be analyzed into at least one analog signal finally, employing the analog signal to extract the energy of a fixed bandwidth from the signal to be analyzed and stopping generating the driving electric signal while the energy is larger than a predetermined value. This invention uses the low frequency signal with high transmittance as the analysis signal to precisely determine the optimal ultrasound working time for brain to increase the permeability for the local blood brain of the brain.本發明係揭露一種超音波收發處理系統及其處理方法,首先,產生一驅動電訊號,接著,依據電訊號往一反射位置發射具有一主頻率之至少一第一超音波訊號,並藉由位於此位置之一物體,如大腦之局部微血管,反射第一超音波訊號,以形成至少一第二超音波訊號。再來,從第二超音波訊號擷取頻率小於主頻率之欲分析訊號,並排除接收其他訊號,以轉換欲分析訊號為至少一類比訊號。最後,其係利用類比訊號擷取欲分析訊號之一固定頻寬之能量,並在其大於一預設值時,停止產生驅動電訊號。本發明使用高穿透率之低頻訊號作為分析訊號,以精準地判斷腦部之最佳超音波作用時間以增加腦部局部血腦之間通透度。10‧‧‧電訊號收發分析裝置12‧‧‧第一超音波換能器14‧‧‧第二超音波換能器16‧‧‧物體18‧‧‧超音波發射裝置20‧‧‧超音波分析裝置22‧‧‧聚焦超音波控制器24‧‧‧相位產生器26‧‧‧功率放大器28‧‧‧類比數位轉換器30‧‧‧處理器32‧‧‧時間延遲器
