Product Introduction:

EDUMR Magnetic Resonance Imaging Technology Experimental Instrument(Medical Imaging and Magnetic Resonance Imaging Teaching Device _ Medical Physics and Magnetic Resonance Imaging Teaching Device)It is a small desktop MRI instrument designed specifically for teaching experiments in MRI technology. Experimental courses such as principles of magnetic resonance imaging and magnetic resonance imaging demonstrations can be offered in conjunction with 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. (Medical Imaging and Magnetic Resonance Imaging Teaching Device _ Medical Physics and Magnetic Resonance Imaging Teaching Device)
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

Application Case 1: Experiment on Nuclear Magnetic Resonance Principle

The effect of non-uniformity of the main magnetic field on tissue T2 *

Application Case 2: Magnetic Resonance Imaging Technology Experiment

Magnetic resonance oil-water T1 and T2 weighted imaging

The characteristics of T1 weighted image are: the shorter T1, the stronger the signal; The longer the T1, the weaker the signal. The characteristics of T2 weighted images are: the longer the T2, the stronger the signal; The shorter the T2, the weaker the signal. The above figure shows a comparison of T1 and T2 weighted images of a sample of oil-water mixture.

Application Case Three: Analysis of Relaxation Rate of Contrast Agents
