The 1430 LE is designed to provide asonographer with advanced designfeatures that allow for both Dopplerand B-Mode
ultrasound system tests inone unit. This product consists of the flow system, phantom, and electric flow controller meter.
The B-Mode Phantom component of the 1430 LE is based onour 404GS LE model that provides advanced technologyfor
measuring image quality on small parts and intracavityultrasound scanning systems. With added greyscale targets this
small parts phantom also measurescontrast, temporal resolution and system linearity. Thephantom incorporates the
Gammex Tissue Mimickinggel which provides a smoother background textureand composite film scanning surface that
hasimproved transmission properties.
Unique to the 404GS LE phantom are the closelyspaced pin targets. By spacing them closer together,our targets are ideal
for testing a range of highfrequency transducers. Resolution patterns and allvertical and horizontal pins are made of
0.1 mmnylon fibers for better detail definition and spatialresolution. Three grey scale targets of -6 dB, +6 dBand +12 dB
relative to the backgroundmaterial are included. A series of anechoic cysts withdiameters of 1, 2, 4 and 7
mm permit easy evaluationof system noise and distortion parameters.
Two 4 mm vessels are incorporated into the system tomeet with FDA Doppler sensitivity recommendations. One vessel is
parallel to the scan plan at 2 cm, andthe other vessel descends 35 degrees from the surfaceand is used for measuring
Doppler sensitivity and fordeveloping scanner techniques.
This self-contained system provides a broad range ofavailable flow rates and test objects. The enhancedmicroprocessor-
based flow controller meter producesaccurate flow rates from 1 to 17 ml/sec correspondingto 0 to 174 cm/sec measurable
velocities with a1% full scale (FS) accuracy.
The 1430 LE provides a realistic test mediumfor assessing:
• Maximum signal penetration
• Channel isolation of directional discrimination
• Registration accuracy of duplex sample gates andsimilarities between B-Mode and color flow images.
• Flow rate readout accuracy
The Gammex 1430 LE is an all-in-one portable systempowered by a built-in LI/ion rechargeable battery.The universal
charger is included with the system.

Model1430 LE
The 1430 LE is designed to provide a sonographer with advanced design features that allow for both Doppler and B-Mode
ultrasound system tests in one unit. This product consists of the flow system, phantom, and electric flow controller meter.
The B-Mode Phantom component of the 1430 LE is based on our 404GS LE model that provides advanced technology for
measuring image quality on small parts and intracavity ultrasound scanning systems. With added grey scale targets this
small parts phantom also measures contrast, temporal resolution and system linearity. The phantom incorporates the
Gammex Tissue Mimicking gel which provides a smoother background texture and composite film scanning surface that
has improved transmission properties.
Unique to the 404GS LE phantom are the closely spaced pin targets. By spacing them closer together, our targets are ideal
for testing a range of high frequency transducers. Resolution patterns and all vertical and horizontal pins are made of
0.1 mm nylon fibers for better detail definition and spatial resolution. Three grey scale targets of -6 dB, +6 dB and +12 dB
relative to the background material are included. A series of anechoic cysts with diameters of 1, 2, 4 and 7
mm permit easy evaluation of system noise and distortion parameters.
Two 4 mm vessels are incorporated into the system to meet with FDA Doppler sensitivity recommendations. One vessel is
parallel to the scan plan at 2 cm, and the other vessel descends 35 degrees from the surface and is used for measuring
Doppler sensitivity and for developing scanner techniques.
This self-contained system provides a broad range of available flow rates and test objects. The enhanced microprocessor-
based flow controller meter produces accurate flow rates from 1 to 17 ml/sec corresponding to 0 to 174 cm/sec measurable
velocities with a 1% full scale (FS) accuracy.
The 1430 LE provides a realistic test medium for assessing:
?Maximum signal penetration
?Channel isolation of directional discrimination
?Registration accuracy of duplex sample gates and similarities between B-Mode and color flow images.
?Flow rate readout accuracy
The Gammex 1430 LE is an all-in-one portable system powered by a built-in LI/ion rechargeable battery. The universal
charger is included with the system.
The Model 1425A LE Doppler Flow System tests both Doppler and B-mode ultrasound systems using one uniquely
designed unit. Gammex combines its low echo matrix with strategically placed line reflectors and anechoic cyst targets at 2,
4, and 6 mm depths. Two 5 mm vessels are incorporated into the system to meet with FDA Doppler sensitivity
recommendations. One vessel is parallel to the scan plan at 2 cm, replicating a carotid artery. The other vessel descends 45
degrees from the surface to test Doppler sensitivity and to train different scanner techniques. All of this is combined with a
flow controller with microprocessor that has a range of 1 to 12.5 ml/sec within 3% FS accuracy. You can access five
programmable test programs and five preset pulse flow patterns with the easy-to-use display panel. This allows for accurate
reproducible testing time after time. Click for More Details
