MRIjx is mainly used for class display and lab experiments in the majors of modern physics, medical imaging and biomedical engineering. The system features remote control, which allows for students to
do experiments at any time and place. With it's advanced functions and user-friendly design, MRIjx is a specialized experimental instrument of high performance with reasonable price, thus offering great value.
Features:
Characteristic:
MRIjx has three obvious characters: openness, authentic, online teaching function
- Openness. Hardware and software all have high openness.
- Hardware: it can simulate Continuous wave type NMR, and it can be torn down and set up. Fitting with oscilloraph and multimeter, it can practice the Beginning ability and let students be familiar with hardware system.
- Software: the original K space data is openness. So users can do image re-construction experiments. Aim at data processing and signal processing subject, it can offer lots of real and effective data for students and teachers,
consequently the development research of arithmetic optimize and image after-processing can be done.
- Authentic. The interior modules are the same as medical MRI system and core analyzing NMR system for petroleum exploration.
- Online teaching function. For enhance the instrument’s Using efficiency, we designed the online teaching function. Thus the students can operate the machine through internet after class or before class.
The MRIjx is special for teaching experiments, and it fits the develop of modern teaching thought.
