Combination Modes
2D (B-mode) can be used in combination with other modes. (The terms duplex and
triplex imaging refer to combinations of 2 or 3 modes.)
The available combinations are:
To return to imaging with 2D alone after you have been using it in combination with
other modes, double-tap
2D or tap Home .
To add another imaging mode:
•
Tap Col , Pw or 3D .
To remove an imaging mode from the combination:
•
Tap the mode you want to remove.
To return from a combined mode to B-mode only:
•
Double-tap 2D .
Tissue Harmonic Imaging (True Echo Harmonics – TEH)
Tissue harmonic imaging can reduce noise and improve the clarity of the ultrasound
image.
In normal 2D imaging, the transducer uses essentially the same frequency range for
both transmitting and receiving. In harmonic imaging, the image is created by
receiving higher frequencies (harmonics) that are multiples of the transmitted
frequency (f). Tissue harmonic imaging in the bkSpecto is based on the 2nd harmonic
(2f) spectrum and pulse inversion.
Using TEH
TEH can be used only with transducers that support harmonic imaging.
Each preset that permits TEH has default settings for overall gain, TGC gain, contour
level, and contrast level for tissue harmonic imaging.
