Glossary
Apodization – A weighting function used as means of reducing
side lobes in the beam.
Application Entity – A node in a DICOM network.
Back End – System block on the user interface side that
contains master controller, signal processing, image memory
and video layout, peripheral and user interface.
BCM – Company that manufactures motherboards for OEM
equipment.
Beamforming – A common signal processing technique used to
enable directionally or spatially selected signals to be sent or
received from sensor arrays.
Color Power Angio – A Philips trademarked method for better
visualizing small blood vessel networks.
Digital Imaging and Communications in Medicine – A medical
imaging standard for file format and network communications
protocol for file sharing between entities capable of sending
and receiving patient data and images in DICOM format.
DisplayPort – A digital display interface standard administered
by the Video Electronics Standards Association (VESA).
Doppler effect – Change in the frequency of a periodic event
(such as sound waves) due to a change in distance between the
source and the observer.
Doppler Range Gating – Range gate circuit only allows Doppler
shift data from a user specified area to be displayed as output.
Dynamic Host Configuration Protocol – A standardized
network protocol used on IP networks for dynamically
distributing network configuration parameters. IP addresses
and networking parameters are requested automatically from
a DHCP server, reducing the need to configure these settings
manually.
Electromagnetic Interference – (EMI) is when a radio
frequency (RF) transmitting device interferes with the
operation of another electronic device. In a healthcare
environment wireless EMI can cause medical equipment to
malfunction.
Front End – System block that collects data; probe interface,
transmitter/receiver, beamformer, front end controller.
Harmonics – Ultrasound method that generates images using
twice the frequency of the transmitted sound.
