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 ...

Pressure control in medical diagnostic ultrasound imaging

Автор: Jeffrey Stoll

Contact pressure from a transducer is controlled in medical diagnostic ultrasound imaging. Rather than measuring pressure directly using a pressure sensor on the transducer, the compression of tissue within the patient may be measured using ultrasound scanning. The desired amount of compression in the region of interest for diagnosis may be obtained. For example in breast imaging, the desired compression for imaging a portion of the breast is compared to compression measured from ultrasound data. Once the desired tissue compression is achieved, the pressure applied by the transducer is maintained while the diagnosis scan occurs. For example, a robotic arm locks or otherwise maintains the pressure during scanning.

An ultrasonic diagnostic imaging system produces contrast enhanced images which are processed differently during different stages of contrast agent wash-in. During an initial stage of contrast wash-in, imaging is done using pixels processed by maximum intensity detection, to better reflect the rapid change in contrast intensity. During a later stage of contrast wash-in, time averaged processing is used to diminish the effects of noise and motion on the pixel values. During an intermediate period of peak enhancement, a combination of both pixel values processed by both techniques is used. In another aspect, a wash-in period can be characterized by an appearance stage, a growth stage and a peak stage, in which contrast pixel data is adaptively processed in different ways during these periods.
