17-2 z.one ultra and z.one ultra sp OPERATOR MANUAL

Curved Array

Transducer

Identified by the letter C (curved) and a pair of numbers (6-2) = e.g., C6-2. The

numbers corresponds to the optimum frequency bandwidth expressed in MHz.

The transducer elements are electrically configured to control the characteristics

and direction of the acoustic beam.

DDP Data Display Box: The DDP is a reserved space in the bottom-right corner of the

image area (on the LCD Display) in which information is displayed about depth of

measurement cursor, velocity, and other assorted calculation values.

DICOM Digital Imaging and Communication in Medicine: An industry standard used for

the storage and printing of digital imaging and associated measurement data files

across a wide spectrum of disciplines in the medical field.

Dual Imaging feature allowing simultaneous display of two different images on the

screen, operating in different modalities (i.e. Color Flow and Power Doppler)

FDA Food and Drug Administration: A government agency responsible for ensuring

safety to humans in the use of products produced or sold/used in the United

States of America.

Harmonics Harmonic imaging: An imaging feature that can be selected on the z.one ultra,

which transmits at one frequency and receives at a higher harmonic frequency to

reduce noise and clutter and improve resolution.

JPEG Joint Photographic Experts Group: The original name of the committee that wrote

the JPEG image file standard, that is designed for compressing either full-color or

gray-scale images.

Linear Array

Transducer

Identified by the letter L (linear) and a pair of numbers (10-5) = e.g., L10-5. The

numbers corresponds to the optimum frequency bandwidth expressed in

MHz.The transducer elements are electrically configured to control the

characteristics and direction of the acoustic beam.

M-Mode Motion Mode: A way to show the motional behavior of cardiac structures (valves,

heart wall, etc.). A single beam of ultrasound is transmitted and reflected signals

are displayed as dots of varying intensities in a time axis display.

MI Mechanical Index: An indication of the likelihood of mechanical bio effects

occurring. The higher the MI value, the greater the likelihood of mechanical bio

effects.

MPPS Modality Performed Procedure Step: An advanced DICOM service function.

MPPS consists of a network connection between the z.one ultra and a HIS/RIS

management system. The MPPS service allows for defining specific imaging

sequences (steps) to be performed on the patient, and transfer of resultant

images and data, based upon a specific clinical modality.

NTSC National Television Standards Committee: A video standard format setting used in

the United States, and a number of other countries worldwide. See also PAL.
