Product Introduction:

EDUMR Magnetic Resonance Imaging Technology Experimental Instrument(Medical Imaging Teaching Equipment _ Magnetic Resonance Imaging Teaching Equipment _ Magnetic Resonance Teaching Experiment Equipment)It is a small desktop MRI instrument designed specifically for teaching experiments in MRI technology. Experimental courses such as nuclear magnetic resonance principles and magnetic resonance imaging demonstrations can be offered in conjunction with physics related majors (such as modern physics, applied physics, radio physics, electronic information engineering, etc.) and medical related majors (such as large medical devices, medical imaging technology, biomedical engineering, etc.); Open laboratory courses on equipment hardware structure can also be offered in conjunction with nuclear magnetic resonance engineering majors. EDUMR can assist in building the following platforms:
1. Teaching demonstration platform;
2. Magnetic resonance imaging experimental platform;
3. Scientific research experimental platform;
4. Magnetic resonance continuing education and further education platform.
Two major characteristics: openness and authenticity.
Openness:Both software and hardware have a high degree of openness.
1. Hardware openness: This is reflected in the ability to simulate continuous wave nuclear magnetic resonance experiments during experimental teaching, engineering training, and classroom demonstrations, as well as on-site disassembly and assembly of hardware structures. Combined with auxiliary tools such as oscilloscopes and multimeters, it can not only exercise students' hands-on ability, but also enhance their understanding of the hardware structure of instruments, which can meet the requirements of modern experimental teaching for students' practical ability;
2. Software openness: mainly reflected in the openness of K-space raw data, which can be used for simulation experiments of image reconstruction. For signal processing and data processing directions, it can provide students and teachers with a large amount of real and effective data, so as to carry out more extensive research on algorithm optimization, image post-processing, and other aspects.
Authenticity:
EDUMR has the same modules as medical magnetic resonance imaging machines, allowing for a real experience of the principles, instruments, and applications of magnetic resonance imaging.
EDUMR can meet users' requirements for teaching experiments and is an experimental instrument that conforms to the development of modern teaching.
Technical indicators:
1. Magnet type: permanent magnet; Magnetic field strength: 0.5 ± 0.08T;
2. Probe coil diameter: 15mm;
3. What is the effective sample detection range? 12.5mm×H20mm；
4. Imaging quality: The linearity (x, y, z directions) of the image is greater than 90%, and the spatial resolution is better than 0.08mm;
Size specifications (length, width, height):
1. Overall appearance: approximately 1685mm × 530mm × 470mm
2. Weight: Approximately 138K in total weight
