**: The home of equipment, unauthorized shall not **
MRI technology, as another major technology after CT medical imaging, has promoted the rapid development of medicine, neurophysiology and cognitive neuroscience at a rapid speed since the 80s of the 20th century. In recent years, with the continuous breakthrough of technology, the domestic MRI market has changed the situation of relying completely on imports and being controlled by others, and the development of magnetic resonance technology in China has entered a new chapter.
Recently, Neusoft Medical, a leading domestic medical imaging company, once again brought good news to the industry, and its industry's first high-end dual-energy NEUMR Universal 3T magnetic resonance was officially released, realizing the magnetic resonance from 1The perfect leap from 5T to 3T has redefined the domestic brand magnetic resonance industry.
So, what are the technical features and advantages of the high-end dual-energy 3T magnetic resonance newly released by Neusoft Medical?In the face of the pain points that have always existed in the industry, how does Neusoft Medical gain insight into its deep-seated needs and solve them?
Recently, the home of instruments interviewed Ms. Li Yingsa, general manager of the magnetic resonance product division of Neusoft Medical, in order to answer relevant questions for the industry.
The industry's first high-end dual-energy 3T MRI
Redefining 3t magnetic resonance
At present, magnetic resonance imaging has become an indispensable and important diagnostic method for medical imaging. It is reported that according to the different properties of the magnets used, magnetic resonance is usually divided into three types: permanent magnet type, permanent conductive type and superconducting type. High-field superconducting magnetic resonance (MRI) has become an industry trend.
The industry's first high-end dual-energy 3T magnetic resonance equipment newly released by Neusoft Medical adopts a dual-energy gradient system and its unique architecture design to achieve super explosive power and continuously provide strong power for the magnetic resonance system.
Dual-energy: N+1 energy storage module and energy accumulation module
With the development of fast imaging and advanced sequences, magnetic resonance imaging not only requires the instantaneous field strength of the gradient to be higher and higher, but also requires the high gradient field strength to last for a long time.
In order to achieve high current and long-term output capacity, Neusoft Medical has specially launched the industry's first N+1 energy storage module and energy gathering module design to provide the gradient system with super explosive power and staying power.
"The traditional energy storage module only has n groups of energy storage units in each of the XYZ three axes of the gradient amplifier, while the N+1 energy storage module adds one group of energy storage units in each of the XYZ three axes, the purpose of which is to ensure the super explosive power of the gradient output," said Ms. Li Yingsa. ”
As an exclusive and industry-first technology of Neusoft Medical, the concentrating module is also an exclusive design independent of traditional gradient amplifiers, aiming to ensure that the gradient has super explosive power and staying power, ensure the long duration of ultra-high gradient field strength, and ensure better image quality for advanced functional imaging, such as diffusion imaging.
It should be emphasized that as a high-end imaging equipment, it should not only pay attention to the high resolution and signal-to-noise ratio of the image brought by high energy explosiveness and endurance, but also pay attention to the accuracy of the image. In response, Ms. Li Yingsa said: "The unicorn gradient system introduces a linear time-invariant algorithm in the gradient control center system, which is the source of the gradient amplifier, that is, the gradient synchronization 0 delay technology, which can greatly improve the image quality through real-time dynamic and accurate compensation, which is particularly important for advanced functional imaging and sequence development. Therefore, the N+1 energy storage module, the energy concentrating module and the gradient synchronous 0-delay technology constitute the core of dual-energy magnetic resonance. ”
Fiber Optic Distributed Spectrometer
In the composition of magnetic resonance components, the function and performance of the spectrometer, as the brain of the magnetic resonance system, directly determine the efficiency and speed of the magnetic resonance system. The optical fiber distributed spectrometer launched by Neusoft Medical is regarded as the strongest brain of the magnetic resonance system.
It is understood that due to the long R&D cycle, large investment, high risk, multidisciplinary interdisciplinary and highly technology-intensive spectrometer, its core technology has been in the hands of a few foreign-funded enterprises.
The traditional lumped spectrometer, based on the architecture of the backplane plug-in card chassis, can only pass the control instructions to the RF, gradient and acquisition in turn, resulting in slow signal transmissionAt the same time, the signal transmission mode of the cable is very susceptible to external interference, resulting in signal loss, and the system signal-to-noise ratio is reduced," said Ms. Li Yingsa, "Neusoft Medical's optical fiber distributed spectrometer breaks the traditional lumped spectrometer architecture, and the variable signal is transmitted synchronously in turn, and the substation signal is transmitted as an optical signal, and the signal transmission speed is fast and lossless. ”
It is reported that the optical fiber distributed spectrometer launched by Neusoft Medical, from the system hardware to the general system, involves the system correction, sequence platform, reconstruction platform and user interface are independently developed and built, showing excellent real-time, such as: the sequence parameters can be adjusted in real time according to the changes in the patient's physiological state, and the data with scanning errors can be thrown away and scanned, which greatly improves the success rate of scanningIt has good scalability, supporting 8 channels to 256 channels.
Multi-source radio
It should be pointed out that in the R&D and design of magnetic resonance, the increase of field strength will bring about the decrease of RF penetration effect, and the most direct impact is the appearance of dielectric artifacts.
Neusoft Medical's 3T magnetic resonance adopts multi-source emission and is equipped with two independent RF amplifiers, which can adjust the amplitude, frequency, phase and waveform independently, in real time and adaptively according to the actual scanning status, ensuring the stability and safety of the product.
Neusoft Medical's new multi-source launch platform is Multi-Source Launch 20, the more important breakthrough lies in the uniquely designed smart island solution. Ms. Li Yingsa added: "The intelligent adjustment of the circulator between the RF amplifier and the RF coil can intelligently monitor the current generated by the RF coil and isolate the current from being transmitted back to the RF amplifier to ensure the accuracy of the RF amplifier's output signal and improve its stability. ”
In addition, Neusoft Medical's industry-first NEUMR Universal 30T magnetic resonance also adopts the Sky Eye AI positioning system, which automatically recognizes human body images, depth of field information, and 3D contours, which greatly improves the accuracy of positioning. At the same time, it introduces the concept of pyramid AI acceleration, which recognizes low-frequency, medium-frequency and high-frequency images by doing pyramid transformation of the original image, and more comprehensive denoising combined with dual-domain compressive sensing technology to achieve more fidelity and effective acceleration.
Ms. Li Yingsa said: "The high-end dual-energy 3T magnetic resonance released by Neusoft Medical this time, whether it is software or hardware, has achieved 'from scratch, from existence to excellence, from excellence to refinement', and pays more attention to the in-depth needs of the industry while meeting customers. ”

Ms. Li Yingsa emphasized, "Neusoft Medical has completely independent R&D in the field of magnetic resonance and for 3The breakthrough in the field of 0T magnetic resonance also gives it the ability to customize the desired sequence for doctors, so that doctors can do the scientific research they want to do. ”
In fact, in addition to focusing on the market, today's Neusoft Medical should also pay attention to how to deeply participate in the entire path of clinical diagnosis and treatment in hospitals, so as to provide more evidence support and stable tools for the entire process control and doctors' decision-making.
Under the important customer-centric strategy, Neusoft Medical's high-quality services have also shown results. Ms. Li Yingsa said: "At present, Neusoft Medical's equipment has been recognized by major medical institutions and third-party institutions. This stems from the fact that in the process of promoting brand development, in addition to the quality and performance of the equipment, from the application end to the R&D end and even to the wiring, people from various functional departments of Neusoft Medical must go to the client to understand the real needs. Let the customer see the confidence in the brand, the equipment, on the whole team. ”
