Siemens' unique technologies
- Tim 4G: The 4th generation of proven Tim (Total imaging matrix) technology provides a maximum number of 204 channels3 with up to 128 independent receiver channels that can be used simultaneously for the accuracy you need.
- Dot: The next movement in MRI. Dot is a new way of scanning in MRI – a better way. Dot scanning uses a suite of customizable engines. Allowing the user to personalize exams according to patient needs, build in step-by-step user guidance, and automate MRI exams – either "out of the box" or based on the institution's standards.

- TimTX TrueShape: Is Siemens’ parallel transmit architecture. It features selective excitation to highlight regions, organs or features of an organ leading to increased image quality and faster scanning. Builds the foundation for unique parallel transmit applications, like syngo ZOOMit, the first zoom function in MRI.
Magnet technology
MAGNETOM Prisma offers benchmark magnet homogeneity (typ. 1.1 ppm @ 50 cm DSV (diameter spherical volume)) and magnet reliability.
Field strength | 3 Tesla |
Bore size | 60 cm |
Magnet length | 198 cm |
Helium consumption | Zero Helium boil-off technology |
Gradient system
MAGNETOM Prisma comes standard with the XR 80/200 gradient system, the strongest gradients in the industry. The combination of the excellents gradients together with Tim (Total imaging matrix) enables the most demanding applications.
It offers largest anatomical coverage with a FoV up to 50 cm.
Gradients | Maximum amplitude of 80 mT/m @ a slewrate of 200 T/m/s, Simultaneously on all three axes |
RF technology
Tim’s revolutionary all digital-in/digital-out design Direct RF allows for higher SNR and improved stability. All transmit and receive components are located at the magnet.

- Optical links between magnet and equipment room to achieve high RF stability and low noise
- Transmit and receive components are integrated in the magnet housing
- Dual-Density Signal Transfer enables ultra-high density coil designs by integrating key RF components into the local coil
Siting and installation
MAGNETOM Prisma allows for a fast installation. It requires only 33 m2 floor space. No dedicated computer room is required for the electronic cabinets.
System length | 213 cm |
System weight (in operation) | 13 tons |
