摘要：
A method for analysing, identifying, tracking, ranging and displaying pleura (which may be either visceral or parietal pleura) breath signal in millimetre-scale resolution, comprises obtaining signals from an ultrasound probe comprising a puncture needle. Each signal comprises an amplitude and an emission-reception time difference. The time differences are transformed into axial distances between tissue interfaces, and the tip of the puncture needle of the ultrasound probe. The distances are used to produce a distance-signal amplitude image. A region of interest is set in the image and dynamic distances between the tip of the needle 301 and the pleura 302 are instantly displayed and tracked. The method may comprise producing a time-varying distance-signal amplitude image (this may be an M-mode ultrasound image) and displaying tip-pleura dynamic distances at least 20 times per second. The puncture needle may relate to the paravertebral region or intercostal region. A warning signal may be produced when the tip-pleural distance becomes smaller than a set threshold. Also provided is a system to carry out the disclosed method.
