Imaging Modes
The bkSpecto has various imaging modes:
•
2D (B-mode) gives real-time 2D information about the anatomical structure of
soft tissues. Includes tissue harmonic imaging.
•
Color mode (CFM, color flow mapping, color Doppler) ultrasound displays
color-coded, real-time information about direction and velocity of flow in tissue.
•
Power mode (power Doppler) ultrasound displays information about the number
of particles moving, rather than their velocity.
•
Doppler mode (spectral Doppler mode) imaging displays information about the
spectrum of flow velocities as a function of time.
NOTE :
You cannot change imaging modes when the image is frozen.
Adjusting the Thermal Index Limit
Before you use the system, check that the TI settings are appropriate. The current TI
tissue type and limit are displayed in the top left corner of the monitor.
The absolute TI limit for each tissue type is set by the factory to conform to FDA
guidelines and international standards (AIUM/NEMA and IEC) (see the acoustic
output section in the
bkSpecto User Guide ), but you may want to set a lower TI limit
for some purposes. There are 2 types of settings you can vary:
•
Tissue type (TIS – soft tissue, TIC – cranial, TIB – bone)
•
TI limit (not exceeding the factory-set limits)
To select tissue type:
•
Tap TI Type and select TIB , TIC , or TIS :
Figure 7-1. TI Type button.
To adjust the TI limit:
•
Touch and slide the TI scale button to adjust the limit.
