CH 35 - 3D/4D ultrasound
3D ultrasound - correct answer-Imaging technology involving the automatic or manual
acquisition and display of a series of 2D images
3D volume or volume data set - correct answer-Collection of acquired 2D images
4D imaging - correct answer-Continuously updated display of volume information; also
known as real-time 3D ultrasound and live 3D ultrasound
C-plane - correct answer-Coronal plane, also called the Z-plane; often, 2D imaging does not
allow imaging on this reconstructed plane
Digital imaging and communication in medicine (DICOM) - correct answer-Standard file
format for handling, storing, printing, and transmitting information in any form of medical
imaging (i.e., radiology, pathology, laboratory, etc.)
Multiplanar reconstruction (MPR) - correct answer-Display algorithm for viewing more than
one plane simultaneously; frequently sagittal, transverse, and coronal planes that are 90
degrees to each other. Also known as sectional planes or orthogonal planes
Orthogonal planes - correct answer-Planes that are always at right angles (90 degrees) to
each other; typically sagittal, transverse, and coronal
Picture archiving and communication system (PACS) - correct answer-Computer or server
used to store, retrieve, and display digital images and patient information from a variety of
imaging resources
Pixel - correct answer-Smallest unit of a 2D image; has a length and a height
Reference dot - correct answer-Point where all three orthogonal planes intersect within the
volume; depicts the same anatomic point in three orthogonal planes; also called the marker
dot
Region of interest (ROI) - correct answer-Area of data acquisition for the 3D/4D volume
Spatio-temporal image correlation (STIC) - correct answer-Technique used to acquire and
display a volume data set of the fetal heart; the volume displays as a 4D cine sequence of
the beating heart
Surface rendering - correct answer-3D rendering mode that displays the surface or skin of
the body without displaying the underlying anatomy
Threshold - correct answer-Filter used to eliminate low-level echoes
3D ultrasound - correct answer-Imaging technology involving the automatic or manual
acquisition and display of a series of 2D images
