SEMCAD X MRI

SEMCAD X MRI SOLUTION provides a unique software platform for magnetic resonance imaging (MRI) scanner design. The new platform seamlessly integrates powerful new tools for radio-frequency (RF) array design and post-processing, and is the first software of its kind to combine all the tools needed to design RF-phased arrays into a single user friendly program. MUSAIK™ is one key element enabling the user to evaluate simulated array coil designs and assess their parallel imaging capabilities. Equivalent analysis is available for experimentally obtained raw data, allowing accurate design verification for a range of different design processes or to evaluate simulation model fidelity.

Key Applications

• fast and accurate RF field, exposure and SAR calculations
• optimization of field uniformity and SAR for single channel and multi-channel MRI systems
• MRI safety
• analysis of multi-channel MRI data using various signal reconstruction techniques with either simulated or experimental input data
• genetic optimization of RF/microwave structures
