摘要：
The invention provides an intra-needle ultrasound system and its method of use for analysis, tracking, and display of pleura in millimeter scale resolution. This method includes following steps: Assembling the puncture needle and intra-needle ultrasound transducer, which can generate and receive ultrasound at the needle tip. To transform axial ultrasonic signal into a figure, that can help to identify different anatomic structures according to corresponding feature of ultrasonic RF (Radio Frequency) signal. Further to identify the distance from needle tip to pleura during puncture and to set the region of interest according to corresponding RF feature of amplitude and depth. This invention can indicate the distance between the ultrasound needle tip and pleura in a real-time fashion, and to identify the best position for anesthetic injection in paravertebral block (PVB) and intercostals nerve block (ICNB). The system can also help to avoid damage to the pleura and lung during the nerve block procedure.本發明提供一種合併方法及其內針超音波系統，用於肋膜訊號分析辨識、追蹤測距及顯示，其步驟係利用一微型化超音波探針系統裝置於穿刺針內，於穿刺針針尖前端發射及接收超音波訊號，取得軸向深度的複數回波並顯示一個距離與超音波RF(Radio Frequency)回波訊號振幅圖。並依此振幅變化特徵和深度變化特徵，設定一興趣區域，即時顯示該超音波探針裝置針端與肋膜之距離，以作為辨識肋間神經阻斷術及脊測神經阻斷術施行時，最佳的藥劑施放位置，同時避免超音波探針裝置於進行神經阻斷術時，因距離過近而傷害肋膜及其下之肺臟組織。
