R&D of positioning device for magnetic resonance imaging system

2021-12-29

At present, magnetic resonance imaging systems are mostly used for medical examinations. Magnetic resonance imaging is a type of imaging method that does not cause any damage to the human body and is not radioactive. Therefore, pregnant women can also undergo examinations. However, magnetic resonance imaging cannot be performed on patients with pacemakers installed in their bodies, patients with steel nails after orthopedic surgery, or those with intrauterine devices.

When the existing magnetic resonance imaging system is used for examination, many patients may have disabilities or fractures, and most of them cannot lie on the MRI examination table independently for examination. Medical personnel need to assist in locating patients. However, when medical personnel assist patients in lying down, there are still a small number of severely ill patients who are very painful and unable to be assisted in positioning, greatly increasing the difficulty and workload of medical staff, reducing usability and practicality. Therefore, Rich Full Joy proposed the R&D of positioning devices for magnetic resonance imaging systems to solve existing problems.

Rich Full Joy Technical Solution

1.The auxiliary bed board is equipped with uniformly distributed sliding grooves, which are equipped with a rod for transmission. The sliding groove is connected to the first gear rack through the transmission rod. The lower end of the auxiliary bed board is equipped with a motor for transmission, which is connected to the inspection bed. The lower end of the inspection bed is equipped with a leg for support, and there is also a square block for transmission. The outer end of the square block is equipped with a motor for transmission, and the inner end is equipped with a rectangular groove for lifting and sliding of the telescopic transmission block. The square block is connected to the auxiliary bed board through the telescopic transmission block, and the other end of the inspection bed is connected to the magnetic resonance equipment.

2.Using magnetic field sensing technology to perceive the strength and direction of the magnetic field to ensure accuracy during the imaging process.

3.High precision position tracking technology precisely controls the position and direction of the imaging area, achieving real-time monitoring and adjustment functions.

4.The imaging parameter control technology real-time controls the imaging scanning speed, resolution, signal-to-noise ratio, etc. of the magnetic resonance imaging system, improving imaging quality and accuracy.

Rich Full Joy Innovative Points

1.By setting the clamping block, the lower end of the clamping block slides through the sliding block in the sliding groove, thereby adjusting the spacing at the auxiliary bed board and limiting the position of the patient.

2.The clamping blocks are distributed at both ends of the auxiliary bed board, and the transmission is separate, which can provide a certain center axis offset limit according to the specific situation of the patient, improving the practicality of the device.

3.By setting the telescopic transmission block, the square block adjusts the extension height of the telescopic transmission block through transmission, thereby driving the auxiliary bed board to rotate along the rotation axis, facilitating the placement of patients at the auxiliary bed board, effectively reducing the difficulty of medical staff's work and improving work efficiency.
