MÁY CHỤP CỘNG HƯỞNG TỪ-Model: NSM-P035

29/10/2009 21:06

FGI-NSM-P035
FGI-NAM-P023A
Features
  • Bi-polar C type magnet, a current worldwide fashion type
  • Minimal floor space, easy to operate, low cost for maintenance
  • High performance and stability with advanced gradient system, RF system and spectrometer
  • Practical imaging, functions: MRA, MRCP, EPI, etc.
  • Practical clinical sequence, Diffusion/Perfusion
  • 3D thin-slice images can show structure s detail
  • Easy to position and quick scanning for increased patient output
  • Advanced PC system based on P4 2GHz with 1GB RAM
  • Smart, usable, and flexible interface
  • Free update of software
Advanced Magnet Design
  • FGI-NSM-P035 has the highest magnet strength in a permanent MRI system, with a SNR of more than 0.2T(166%). The image quality can be compared with a middle field MRI system.
  • Bi-polar C type magnet is open in four directions, which makes patient feel safe. Any part of body can be located in the center of the magnet to ensure high quality images and to be convenient for interventional therapy.
  • Applying a special patented technique, the permanent NdFeB materials can ensure super high homogeneity of the magnetic field and remove eddy current completely.
  • Equipped with a high-precision, self-regulating-temperature device, the magnetic field is super stable and the working temperature requirement is easy to maintain.
  • Separated from the magnet and equipped with laser localizer, patient table can move in two directions.
Imaging
  • Multi-angle/multi-slice scanning: Multi-group with multi-angle/multi-slices in one scan protocol make the imaging of neck/spine/L-spine and c-spine much easier and more flexible
  • Fractional Echo: Fractional echo technique shortens the echo time, increases the T1 contrast, and reduces the effect of the T2 at the same time, increasing the slice number in the given TR. Half scanning/reconstruction reduces the scan time
  • Flow Compensation Technique: FGI-NAM-P023A flow compensation technique can remove the flow artifacts, making the image of the spine more clear
  • Anti-aliasing Techniques: Frequency/phase oversample can remove the aliasing artifacts, obtaining excellent quality small FOV images
  • Multi-region Pre-saturation Technique:
    • Drawing multi-regions are flexible and can be saturated on the pilot image to remove or minimize the artifacts from breathing or abnormal signal of the ROI
    • Optimized bandwidth according to the TE, samples points in sequence automatically, ensure to get the highest SNR images
    • Optimized data acquisition including frequency under/over sampling and echo asymmetry techniques
    • Gated-scanning technique
    • ECG-gated scanning
  • Provides many combinations of the phase encoding sequence, suitable to different scanning situations such as the critically ill or patients who cannot remain still for a long scanning period
Computer System
  • Main Computer System:
    • P4, 2.0GHz, dual-CPU
    • Windows2000
    • 1024MB memory
    • 80GB Hard disk, which can store 600,000 images.
  • Removable Magneto-Optical(MO) Storage:
    • 1.3GB
    • User can view images, analyze and make statistics on the MO device itself or transfer data between the hard disk and the MO drive.
  • Monitor:
    • 21" high resolution (1600 x 1200) color monitor
  • Spectrometer:
    • Based upon Windows NT workstation to allow simultaneous scanning and reconstruction
    • Scan can be interrupted at anytime.
    • Reconstruction time<0.1sec. (Matrix: 256 * 256)
  • Laser Imager Interface:
    • Digital interface compatible with DICOM 3.0
    • Can be connected to most well-know laser imagers or to the devices conforming to the DICOM3.0 standard
  • Patient Monitoring:
    • Intercom
Multiple Receiver Coils
  • FGI-NSM-P035 offers a rich lineup of coils with designs to fit all anatomical regions.
  • Head coil and body coil are both QD two-channels. SNR can be improved by about 40% higher than conventional solenoid coil.
  • Flexible body boil can fit different shaped patients as well as improve fill factor to get better image.
  • Flat coil for spine imaging dramatically increases the clarity of image in ROI.
  • Equipped with extremity coil and breast coil.
  • Coils Offered:
    • Neck Coil
    • Flat Spine Coil
    • QD Head Coil
    • QD Body Coil
    • Joint Coils for Knee, Extremity, etc.
    • Breast Coil
SuperOpenView Software
  • Well-designed human interface, completely operated by mouse
  • Scan, reconstruction, image view, image processing, and filming can be performed in parallel
  • Supports priority scanning with patient pre-registration
  • Secure management of patient information and scan authorization
  • Self defined sequences and sequence list shorten the exam time and make it easy to operate
  • Real-time display of multiple images and multi-sequence image contrasts
  • Easy to switch the images among 5 image cache areas
  • Special image filtering software aims at the special part, direction, sequence and slice thickness.
  • 6 types of filtering
  • Magnify, zoom, rotation, conversion, movement, combination, cut/paste and continuous windowing
  • Measurement of point/line/area and ROI statistic (Maximum, Minimum, standard deviation standard, distance, etc.)
  • Image annotation (Arrow and characters annotation)
  • Cine display
  • MIP
  • MRP
  • Filming:
    • Transmission by DICOM interface
    • Printing Preview
