3D Imaging
Introduction to 3D Ultrasound
The basic concept of 3D ultrasound is to collect a data set of 2D ultrasound images
(black & white or color) while tracking and storing the location of each individual
2D image. The data set is then reconstructed into a single 3D volume that can be
displayed on the screen and manipulated. The reconstructed 3D volume can be
rotated, sliced, rendered or displayed in multiplane cross-sections.
3D on the Pro Focus
The 3D function of the Pro Focus can be purchased as an option. For more
information, see “Specifications” on page 335.
To run the 3D software, you must have a license from B-K Medical. For information
about activating the 3D option, see “Licenses” on page 196.
Password Protection
If your patient archiving system is password protected (see “Password Protection of
the Database” on page 115), you cannot use the 3D system unless you are logged in.
Emergency
In an emergency, you can put the scanner into an Emergency state and acquire 3D
data sets, but you cannot save them with any patient ID other than EmergencyID.
See “Emergency State” on page 116.
Scanning Modes
You can use 3D with B-mode, Color mode or Power mode scanning. However, you
cannot use 3D with the following modes and functions:
•
Doppler mode (spectral PW Doppler)
•
CW Doppler
•
M-mode
•
Split-screen
•
Color mode (ve variance submode)
•
Power mode (power + velocity submode)
•
ECG
•
B Color
NOTE:
Turning on one of these modes or functions while you are using 3D will
turn off the 3D system. If you are already using one of these modes, turning on
3D on will turn the mode or function off, and turning off 3D will not turn it on
again.
