MRI - Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a non-invasive diagnostic technology that produces physiologic images based
on the use of magnetic and radio frequency (RF) fields. The MRI system uses powerful magnets to create a magnetic field that forces
hydrogen atoms in the body into a particular alignment (resonance). RF energy is then distributed throughout the patient and disrupted
by body tissue. The disruptions correspond to varying return signals, which, when process, create the image.
Accurate signal processing is key to obtaining high quality images. Analog and DSP products help control the magnetic
and RF energy in the MRI, and delivers the high resolution required to accurately define the area of the patient to be scanned. TI offers
a wide variety of products for MRI systems and equipment manufacturers, including:
