Medical Imaging
Designing MRI EquipmentMagnetic resonance imaging (MRI) is a medical imaging technique using radio waves and magnetic fields to create detailed cross-sectional images of internal organs and structures within the body. Widely used in patient analysis and medical diagnosis, MRI often reveals different information about bodily structures than can be visualized using other imaging methods such as X-ray, computed tomography (CT) or ultrasound.

Our medical solutions portfolio is aligned to help you deliver innovative implantable device therapies, diagnostics and monitoring solutions enabling better patient care and quality of life. Contact your local Microsemi sales office today to find the right technologies and products for your medical imaging design needs. Component Clocks: RF Oscillators for MRI EquipmentMagnetic resonance imaging (MRI) equipment requires a local reference oscillator, in order to serve as a source for all the RF components in the multiple MRI circuit boards. Microsemi's Rubidium MAC (Miniature Atomic Clock) is ideal for medical imaging applications to serve as this local reference oscillator.Rubidium MAC Advantages for MRIs
SiC Diodes/FETs for MRI Power Conversion
Silicone Carbide (SiC) Schottky Diodes and MosFETs offer superior dynamic and thermal performance over conventional silicon power diodes and MosFETs. The table below summarizes the advantages of SiC vs Si power discretes.

Non Magnetic TVS: Data Integrity in MRIsData lines are susceptible to transient surges, and TVS arrays are typically used to suppress these transient surges. In MRIs (large magnetic field) the material used to construct TVS arrays can also be affected, reducing their effectiveness. Traditional TVS Arrays use the copper alloy A194 to make leads stiffer, which is unacceptable in harsh magnetic environments. Microsemi's Non-Magnetic TVS arrays use a different alloy, with 0% iron content, and full compatibility with MRIs. In order to deal with the inherent higher flexibility of the non-magnetic alloy, compared to Iron, Microsemi's non-Magetic TVS arrays use a QFN143 package, which is 100% compatible with the traditional SOT143. In a QFN143 package, the epoxy case prevents the leads from bending. All USBQNM504xxx TVS Arrays support 500W (8/20us pulse), protecting a single line. Non-Magnetic TVS array selection table
