Flow 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.

Doppler Flow System Model 1425A LE

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.
