1,5 T Super-Conductive MRI System
The i_Space 1.5T system is a medical diagnostic magnetic resonance system. The system composed by 1,5 T Super-Conductive magnet, patient table, 8 channels spectrometer, gradient system, digital RF transmitting & receiving system and imaging workstation.
Why do we suggest WDM 1.5T system?
1. Advanced design of magnet, which features “zero” helium boil-off, short bore and high homogeneity (please refer to the magnet
specification).
2. Optical fiber transmitting minimizes loss of signal and greatly increase SNR.
3. Mobile device remote control and review (Optional).
Magnet
Brand new i_Space 1.5T magnet presents the latest technology of short bore and “zero” helium boil-off. 60cm open bore design combining with ultra-short bore length of 150cm will effectively relieve patient from anxiety and emotional distress. Very low helium consumption will save huge cost of maintenance.

Patient table
The patient table is used for positioning the patient with corresponding RF receiving coils to the iso-center of the magnet for the scanning of MR.
The patient table unit includes two parts: patient table and positioning system. The fully automatic patient table is easy for patient to access and positioning. Laser positioning system combined with LCD display screen, helps doctor to position patient simply and
quickly.

Digital RF system
The flat quadrature transmitter coil is integrated in the pole pieces providing a strong uniform field. The 20 kW RF power amplifier allows short pulses to be used, ensuring the execution of fast imaging sequences available now and those of the future.
o Operating Frequency: 63.87MHz
o Transmitting Power: 20KW
o Acquisition Band Width: 1MHz
Phase Array RF Coils
The i_Space 1.5T RF coils provide excellent signal to noise ratio, due to presence of low noise pre-amplifiers in all elements of the coils and other receiver coils, ensuring proper enhancement of the signal. Intelligent Coil Identification System makes sure the connected coil is in normal condition.
o Coil Design: Phase Array coil
o RF Coils: 6 independent receiving coils
