I_Open 0.36T Magnetic Resonance Imaging System

Introduction

•  Homogeneity, Large Gap Space, small size and light weight.
•  The Eddy Current is reduced to the minimum through the use of Special High Resistance Materials.

 

Gradient System

•  The Advanced Design of the Inversion Method provides the Gradient System with Very High Linearity and Slew Rate, and
   insures the Highest Image Resolution.
•  I_Open's Unique design of the Active Shield Flat Gradient System decreases the Eddy Current to a very minimum and
   completely avoid the problem of Eddy Current that trouble most of the Permanent MRI Systems.
•  Image quality is improved greatly over similar Open Magnet Systems.

 

RF Transmitter System

•  Quadrature Design of Flat Transmitter Coil has contributed to improved uniformity and efficiency of the System and makes
   the System Unique as a fully open type MRI. The pulse transmitting power is up to 6KW.

 

RF Receiving System

•  The Special design of Quadrature Receiving Coil GreatlyImproves the signal to noise ratio.
•  Low noise build-in preamplifiers in the Coils reduce the signal attenuation, this in terms reduces the effect of noise greatly.
•  Auto Tuning simplifies the System's operation and keeps the System working in the best condition.

 

Friendly Interface & Easy operating

Powerful scanning software

I_Open provides Scan Control Software to help the customer easily set up Imaging Scans and Monitor the scans in a easy and friendly way: Easy and well designed menu are provided to set up scan parameters; Pilot scans allow you to precisely set slice positions; Easy menu also allows you to select Imaging Sequences: Auto adjustment of Resonance Frequency; Auto adjustment of Receiver and Transmitter Gain; Auto adjustment of Shimming; And Scan Process Monitoring in real time is also included.

 

Plenty of imaging processing functions

I_Open MRI system provides the most powerful Image Display and Process Software available on any Present Open MRI: Multi-Window Display; Display Window Adjustment; Image Zoom; Image Rotating; Distance Measurement; Angle Measurement; Region of Interesting Process; Image Enhancement; Image Smooth; Background Noise Eliminating; Image Text Note; Image Parameter Display; DICOM 3.0 Interface; MIP and MPR of 3D Images.


Software update: Free upgrading of Software are provided within Time Frame determined at Time of Purchase.
