Shims are essential components in MRI systems that ensure the magnetic field is uniform, a critical factor for producing clear and accurate images. There are two main types of shims:
‍
‍Active Shims: These use electromagnetic coils to generate a "corrective" magnetic field.  Think of them like adjustable magnets within the MRI system.  Active shims were popular in older GE models (like the Signa 1.5T Infinity, Excite, HD, and HDxt) and are still found in some newer ones (like the Signa 1.5T Explorer).
‍Pros: Easy to adjust using a Shim Power Supply or a modern MPS (like our MPS2.0).
‍Cons: The magnetic field can drift over time, requiring re-shimming every 2-3 years.

‍Passive Shims: These are thin metal plates strategically placed within the MRI scanner during installation. They are manually adjusted to fine-tune the magnetic field.  Most MRI manufacturers now primarily use passive shimming in their systems.
‍Pros: Once properly adjusted, they rarely need further attention, offering long-term stability.
‍Cons:  Adjusting them requires a specialized and expensive tool called a Shim Camera, and the process itself is time-consuming.

That depends on your service contracts and who bears the cost of helium refills! Active shims might require more frequent adjustments, potentially leading to more service calls and helium consumption.  However, passive shims require a significant upfront investment in a Shim Camera.  Carefully consider these factors when evaluating your service needs and contracts.

Digit Systems provides tools and expertise for both active and passive shimming, including our MPS2.0 which offers integrated active shim control.  We can help you optimize your MRI service operations regardless of the shim technology you encounter.

A Ramp Power Supply, like the MPS2.0 from Digit Systems, is used to control the flow of current to the superconducting magnet in an MRI system. This precise control is essential for safely ramping the magnet up or down during installation, maintenance, or in emergencies.  Our MPS2.0 offers advanced features such as auto-ramp function, multi-OEM compatibility, and integrated active shimming, making it a valuable tool for MRI service providers.

Digit Systems specializes in providing high-quality MRI tools and services, including Ramp and Shim solutions, to MRI service companies. We offer a comprehensive range of products designed to improve efficiency, safety, and accuracy in MRI maintenance. Whether you need a new Ramp Power Supply, assistance with shimming, or other specialized tools, Digit Systems can help you optimize your service operations.

The MPS2 offers several advantages over traditional ramp power supplies, including:Ultra-compact design: Improved portability between service sites and countries.Multi-OEM compatibility: Supports compatible GE, Siemens, and Philips MRI systems.Integrated active shimming: Streamlines active shimming on compatible GE LCC magnets.Auto-ramp function: Simplifies ramping procedures and helps reduce human error.Enhanced safety features: Supports safe and reliable ramping operations.Faster job completion: Helps reduce ramping time and helium consumption.
