3D Imaging
Introduction to 3D Ultrasound
The basic concept of 3D
1
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 monitor and manipulated. The reconstructed 3D volume can be
rotated, sliced, rendered, or displayed in multiplane cross-sections.
Imaging Modes
On bkSpecto, you can use 3D with 2D, Color mode, or Power mode imaging.
However, you cannot use 3D with the following modes and functions:
•
Doppler mode (spectral PW Doppler)
•
2D Tint
NOTE:
Turning on one of these modes or functions while you are using 3D will turn
off 3D. If you are already using one of these modes, turning on 3D will turn the mode
or function off, and turning off 3D will not turn it on again.
NOTE:
Acquiring a 3D volume with some color maps may result in faulty colors for
some pixels. To avoid this, the system selects a default pure grayscale instead.
Making measurements on a 3D cube is not the same as making measurements on a
2D image, as described in Chapter 5, “Making Measurements”.
3D License
The 3D function of the bkSpecto can be purchased as an option. For more
information, see the
bkSpecto Product Data Sheet that accompanies this user guide.
To run the 3D software, you must have a license from BK Medical. For information
about activating the 3D option, see “License Tab” on page 154.
Controlling Transducer Movement
The 2D images in the data set are imaged with the transducer in different positions.
The transducer can be moved in the following way:
•
With a system-controlled positioning device (external or built into the
transducer)
•
Untracked freehand (see warning below).
