C – Inter-IC bus, a two wire serial bus for communication
between integrated circuits. Developed by Philips in the 1980’s
it is now an industry standard.
In Plane Switching – A type of thin film transistor LCD screen
that has particularly good wide viewing angle and accurate
color reproduction.
Loops – Multiframe objects (e.g. video)
M Mode – is also known as T-M mode or time-motion mode.
Ultrasound echoes are mapped to a gray scale display by
intensity. Is derived from a stationary beam.
Modality Performed Procedure Step – The modality provides
information about a performed study, the number of images
that were scanned and the status of the exam. The information
is shared between a digital modality and the PACS and RIS.
Multiplexing – Multiple signals transmitted over a single
medium.
Picture Archive and Communications Systems – DICOM
Medical imaging storage server that stores images from
diagnostic devices such as MRI, ultrasound and X-rays.
Phased Array Ultrasound (3D imaging) – Sound waves are
transmitted at different angles to obtain image.
Physio – Refers to ECG inputs.
Protocol Data Units – Message formats exchanged between
peer entities within a layer. A PDU consists of protocol control
information and user data.
PS_ON – Refers to an active low signal used with all ATX and
newer power supplies that use 20-24 pin motherboard
connector. When high all voltages except 5V stand-by are
disabled.
Run-Length Encoding – A lossless compression method
implemented by specifying the number of times a particular
intensity value is repeated.
Synthetic Aperture – An imaging method that improves
resolution and depth of ultrasound images.
Time Gain Compensation – Uses an array of sliding tabs which
control the gain, which compensates for the difference of the
strength of the ultrasound returning from varied distances to
make the ultrasound image appear uniformly lit from top to
bottom.
Thin Film Transistor – A type of LCD display that uses active
matrix technology.
