Terminology Used in This Chapter
Term Definition
blended image An overlay of reference data on a real-time ultrasound image.
electronics unit
Component of the tracking system that provides connections to the
transmitter, the transducer sensors, and the needle sensor.
fuse To align reference data with the same anatomy or area of interest in a real-
time ultrasound image.
image In this chapter, the term image refers to an ultrasound image, reference data,
or a blended image. When a function applies only to specific type(s) of
images, the images types are explicitly named.
landmark A marker on a displayed image used to indicate a point of interest on the
patient anatomy.
level The midpoint of the range of values displayed in the reference data. Adjusting
the window and level settings for reference data is similar to adjusting contrast
in an ultrasound image.
multiplanar reconstruction (MPR) A rendered view of a single plane (axial, sagittal, or coronal) of a volume.
Navigator A list of all planning data and alignments.
needle path A guideline drawn on the reference data for use during an interventional
procedure.
planning data Landmarks, segmentations, and needle paths created for use as references
during an interventional procedure.
reference data A previously acquired data set, for example computed tomography (CT) or
magnetic resonance imaging (MRI), saved in DICOM format.
segmentation The process of identifying the anatomy of interest (foreground) on the
reference data.

Line segmentation identifies the foreground using a line drawn through the
anatomy of interest.

Seed segmentation identifies the foreground (for example, a lesion) and
background (for example, surrounding tissue) using landmarks (seed
points).
tracking system The eSieFusion hardware and software that detects the location and
orientation of the transducer and needle.
window The range of values displayed in the reference data. Adjusting the window and
level settings for reference data is similar to adjusting brightness in an
ultrasound image.
