What MRI Machine Do
An MRI machine creates detailed images of internal organs, soft tissues, and bones using strong magnetic fields and radiofrequency signals. Hospitals and diagnostic centers use MRI systems to diagnose neurological, orthopedic, cardiac, and oncological conditions without ionizing radiation.
An MRI machine uses a powerful magnet and radio waves to produce high-resolution images of the human body without X-ray exposure.
What MRI Machine Do
An MRI system aligns hydrogen protons inside the body using a strong magnetic field.
Radiofrequency coils send pulses that disturb this alignment.
The system measures the energy released when protons realign.
A computer converts this data into cross-sectional images.
Radiologists interpret these images for clinical diagnosis.
MRI scanners rely on hydrogen proton alignment and radiofrequency signals to generate diagnostic images.
Main Components of an MRI Machine
Superconducting Magnet
The magnet creates a constant magnetic field measured in Tesla.
Common strengths include 1.5 Tesla and 3 Tesla.
Gradient Coils
Gradient coils control spatial encoding.
They allow slice-by-slice image formation.
RF Coils
RF coils transmit and receive radiofrequency signals.
Different coils exist for brain, spine, knee, and cardiac imaging.
Computer and Console
The console processes signals into images.
Radiologists control scan parameters here.
Types of MRI Machines Used in India
1.5 Tesla MRI
Hospitals use this as the clinical standard.
It balances image quality and operating cost.
Examples include Siemens Magnetom Essenza and GE Signa Explorer.
3 Tesla MRI
This system provides higher resolution images.
Neurology and research centers prefer it.
Examples include Siemens Magnetom Skyra and Philips Ingenia.
Open MRI
Open MRI improves patient comfort.
It suits claustrophobic and obese patients.
What MRI Machine Do in Clinical Practice
MRI scans detect soft tissue abnormalities with high accuracy.
Doctors use MRI for early disease detection.
Neurology
MRI identifies brain tumors, stroke, epilepsy, and multiple sclerosis.
Orthopedics
MRI visualizes ligaments, cartilage, spine, and joints.
Cardiology
Cardiac MRI evaluates heart structure and function.
Oncology
MRI helps detect, stage, and monitor tumors by providing high-contrast soft tissue images without radiation exposure.
Installation Requirements for MRI Machines
MRI installation needs a dedicated shielded room.
RF shielding prevents external signal interference.
Hospitals require stable power supply and HVAC systems.
Magnetic safety zoning follows IEC and AERB guidelines.
Typical room size ranges from 600 to 800 sq ft.
Floor load capacity must support heavy equipment.
Safety and Compliance Standards
MRI systems follow IEC 60601 safety standards.
Indian facilities comply with AERB safety norms.
Hospitals enforce magnetic safety protocols.
Staff screen patients for implants and metallic objects.
