5.7 TDI Mode
Tissue Doppler Imaging (TDI) mode shows information about low-velocity and high-amplitude
tissue motion, usually used to evaluate cardiac tissue motion. Only Phased transducers support
TDI mode.
There are two types of TDI modes available on this system:
Color-TDI mode: shows the speed and direction of tissue motion on real-time Color image.
PW-TDI mode: shows the speed of tissue motion on Spectral Doppler image.
5.7.1. TDI Mode Operations
To use Color-TDI mode:
1. Press Color mode key on the console.
2.
Press TDI mode button on Color-mode touch screen to invoke Color-TDI mode.
3.
Use the trackpad to adjust the position of ROI box.
While in Color-TDI mode, you can do the follows to invoke PW-TDI mode:
1. Press D mode key on the console and use the trackpad to move the sample volume gate to
desired position.
2. Press D mode key on the console again to invoke PW-TDI mode.
To use PW-TDI mode:
1. Press D mode key on the console and use the trackpad to move the sample volume gate to
desired position.
2. Press TDI mode button on the touch screen to invoke PW-TDI mode.
5.7.2. TDI Touch Screen Controls
Touch screen controls that can be adjusted in Color-TDI mode are the same as those in Color
mode, see section 5.4.1 Color Touch Screen Controls for details. Touch screen controls that can
be adjusted in PW-TDI mode are the same as those in PW mode, see section 5.2.1 PW Touch
Screen Controls for details.
5.8 3D/4D Mode
Depending on the system configuration and regulatory approval, 3D/4D may be available on the
C5-2MQ transducer. The first step in using 3D or 4D is to activate pre-3D or Pre- 4D mode.
There are two ways to activate pre-3D or Pre-4D mode:
Press the 3D or 4D button on the touch screen in B-mode.
1.
Configure the F1 or F2 hardkey to activate Pre-3D or Pre-4D. There are two options to do so,
2.
one labeled '3D' and the other '4D'.
NOTE:
1. Measurement function is not available in 3D/4D mode.
2. Comment and Body Mark functions are supported in 3D/4D mode.
