Medical needle for use in ultrasound imaging |
| 摘要 |
A needle (1) inserted into body tissue (10) is rendered visible to a Doppler ultrasound imager (9) by generating a longitudinal oscillation of the fluid column in the needle barrel by means of a transducer (7) which is energised by a signal of frequency 100Hz to 2kHz, for example. An image (13) of the needle tip (31) is displayed on a screen (12). <IMAGE> |
