深圳灣邊貿(mào)易代理gammex 1430 le 模體價(jià)格優(yōu)惠.多普勒和灰階掃描儀超聲圖像分析體模體 rmi 1430 le 1 美國，gammex公司 原裝美國直接進(jìn)口。

 comes in either 0.5【敏感詞】0.7 attenuation (please specify)

 general:

 the 1430 le is designed to provide a sonographer with advanced design features that allow for both doppler【敏感詞】b-mode ultrasound system tests in one unit.  this product consists of the flow system, phantom,【敏感詞】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【敏感詞】intracavity ultrasound scanning systems. with added grey scale targets this small parts phantom also measures contrast, temporal resolution【敏感詞】system linearity. the phantom incorporates the gammex tissue mimicking gel which provides a smoother background texture【敏感詞】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【敏感詞】all vertical【敏感詞】horizontal pins are made of 0.1 mm nylon fibers for better detail definition【敏感詞】spatial resolution. three grey scale targets of -6 db, +6 db【敏感詞】+12 db

relative to the background material are included. a series of anechoic cysts with diameters of 1, 2, 4【敏感詞】7 mm permit easy evaluation of system noise【敏感詞】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,【敏感詞】the other vessel descends 35 degrees from the surface【敏感詞】is used for measuring doppler sensitivity【敏感詞】for developing scanner techniques.

this self-contained system provides a broad range of available flow rates【敏感詞】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【敏感詞】similarities between b-mode【敏感詞】 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.
