Magnets are widely used in medical equipment, and their diversity and importance cannot be ignored. Here are some main application examples:
Firstly, in magnetic resonance imaging (MRI), magnets play a crucial role. MRI equipment uses superconducting magnets to generate a strong magnetic field, which can cause energy level transitions in atomic nuclei (usually hydrogen atoms) in the human body, thereby releasing energy signals. After these signals are received by the device and processed by the computer, high-resolution images of the internal structure of the human body can be generated. During this process, the magnet not only provides the necessary magnetic field environment for MRI, but also its stability and uniformity are crucial for image quality
Secondly, magnets are also widely used in medical equipment such as insulin pumps, ventilators, and blood separators. The insulin pump uses a magnet to stabilize its operation, ensuring that patients can receive insulin treatment stably. In a ventilator, magnets may be used to provide power to certain components or maintain their stability to ensure the normal operation of the ventilator. The blood separator utilizes the characteristics of magnets to separate different components in the blood, which helps in the diagnosis and treatment of diseases
In addition, magnets are also used in technology to improve daily life under certain conditions. For example, in cochlear implants, magnets are used to fix the head of the cochlea in order to effectively transmit sound to the internal cochlea. In the field of dentistry, magnets are used to assist in preserving dentures and improving the quality of life for patients. For people who use prosthetics, magnetic prosthetic suspension systems help maintain the position of the prosthetics, improve overall comfort, and reduce the maintenance needs of the prosthetics.
