How do I adjust SNR?

The relative Signal-to-Noise Ratio (SNR) shown in the Blue Indicator Box in the Corsmed MRI Simulator, is calculated based on key MRI physics parameters. These include Field of View (FOV), slice thickness, and other contributing factors.

To adjust the Signal-to-Noise Ratio, modify parameters such as:

• Increase Field of View (FOV): A larger FOV increases the amount of signal acquired, improving SNR.
• Increase Slice Thickness: Thicker slices capture more signal and raise SNR.
• Increase Number of Excitations/Averages (NEX/NSA): Acquiring more averages improves SNR at the expense of scan time.
• Choose optimal coil: Use coils with higher channel counts or best fit for the anatomy to get better SNR.
• Adjust Bandwidth: Lower receiver bandwidth can increase SNR, though it may increase artifacts.
