How OPEN MRI Machines Work
OPEN MRI machines operate on the principle of nuclear magnetic resonance (NMR) technology, which involves the interaction of a magnetic field, radiofrequency waves, and hydrogen nuclei (protons) in the body. This technology allows for the detection of detailed images of the body’s internal structures.
The principles behind open MRI technology involve the application of a strong magnetic field to align the hydrogen protons in the body, followed by the use of radiofrequency waves to disturb the alignment and induce signals that are detected by the MRI machine. These signals are then processed to produce detailed images of the body’s internal structures.
The magnetic field generation process in open MRI machines is critical for producing high-quality images. The magnetic field is generated by a superconducting magnet, which is capable of producing a strong and uniform magnetic field around the patient’s body. This magnetic field is typically produced by a circular coil of superconducting material, such as niobium-titanium, which is cooled to extremely low temperatures to achieve superconductivity.
The Role of Gradient Coils in MRI
The gradient coils in an MRI machine are used to shape and control the magnetic field, allowing for the creation of detailed images of the body’s internal structures. The gradient coils are designed to produce a linear gradient of magnetic field strength, which allows for the visualization of specific locations within the body.
- Gradient Coils Generation: The gradient coils are typically produced using a combination of copper and iron wire, which are wound into a cylindrical shape. The coils are then inserted into the MRI machine and connected to a control system that allows for precise control of the magnetic field.
- Gradient Coils Application: The gradient coils are used to shape the magnetic field, allowing for the creation of detailed images of the body’s internal structures. The coils are designed to produce a linear gradient of magnetic field strength, which allows for the visualization of specific locations within the body.
- Gradient Coils Advantages: The use of gradient coils in MRI machines provides several advantages, including improved image resolution, faster scanning times, and increased patient comfort. The gradient coils also allow for the creation of detailed images of specific locations within the body, which is critical for accurate diagnosis and treatment.

Components of an OPEN MRI Machine
The OPEN MRI machine is comprised of various components that work together to produce high-quality images of the body’s internal structures. These components include the magnetic field, RF coils, and control systems, which are designed to provide a comfortable and safe experience for patients.
The Magnetic Field
The magnetic field is a crucial component of the OPEN MRI machine, responsible for generating the magnetic forces that align the hydrogen nuclei in the body. This field is created by a superconducting magnet, which is a coil of superconducting material that is cooled to extremely low temperatures to minimize electrical resistance. The magnetic field is also strengthened by gradient coils, which are used to adjust the magnetic field strength and direction in various regions of the body.
The superconducting magnet is typically made of niobium-titanium alloys, which have high critical temperatures and high critical currents, allowing them to maintain their superconducting state at relatively high temperatures. The magnet is also surrounded by a cryogenic system, which is responsible for cooling the magnet to its operating temperature.
RF Coils and Transmit/Receive Coils
The RF coils, also known as transmit/receive coils, are responsible for generating the radiofrequency signals that are used to excite the hydrogen nuclei in the body. The signal is transmitted by the transmit coil, while the receive coil captures the returning signal and sends it to the computer for processing. The RF coils are designed to provide high-quality images with high signal-to-noise ratios and minimal artifacts.
There are two types of RF coils: static coils and dynamic coils. Static coils are used for structural imaging, while dynamic coils are used for functional imaging, such as functional MRI (fMRI). The dynamic coils are designed to move and adjust their position during the imaging process, allowing for the acquisition of high-resolution images of the brain and other dynamic processes.
Control Systems and Patient Interfaces
The control systems of the OPEN MRI machine are responsible for controlling the various components, including the magnetic field, RF coils, and gradient coils. The control system includes a computer that processes the data and controls the various components, as well as a user interface that allows the operator to control the machine and monitor the imaging process.
The patient interface is designed to provide a safe and comfortable experience for the patient. The patient is placed inside the machine on a table that is designed to be comfortable and adjustable. The interface includes a system for communicating with the patient, as well as a system for monitoring the patient’s vital signs and ensuring their safety during the imaging process.

Patient Experience
The patient experience is a crucial aspect of an open MRI examination. From the moment a patient arrives at the facility to the completion of the examination, every step is designed to ensure comfort, safety, and accuracy. Understanding the steps involved and the importance of patient preparation can help alleviate anxiety and ensure a smooth process.
Preparation and Comfort
Patient preparation is a vital step in ensuring a successful open MRI examination. This includes:
- Removal of any metal objects, such as jewelry or clothing with metal fasteners
- Explanation of the examination procedure and what to expect
- Assistance with relaxation techniques, such as deep breathing or meditation
The patient will be assisted into the examination room, where they will be positioned on a comfortable bed. The bed will be moved into the open MRI machine, and the patient will be secured with straps to prevent movement during the examination.
Throughout the Examination
During the examination, the patient will be monitored by the technologist at all times. The open MRI machine produces a strong magnetic field, and the patient will be asked to remain still and calm. The examination typically takes 30-60 minutes to complete, depending on the complexity of the scans.
Results and Discussion
After the examination is complete, the patient will be asked to wait while the images are reviewed by the radiologist. The patient will be given the opportunity to ask questions or discuss the results with the radiologist.
