  • Ultra high-density coil array for a scan range up to 205 cm with no coil repositioning
  • Light-weight, patient-friendly coils enable more flexibility in patient set-up 
4G Accuracy
  • High-resolution imaging from head to toe with high channel coils
  • Fully digital DirectRF architecture with transmit and receive components at the magnet for true signal purity and stability
  • TimTX TrueForm, providing excellent B1 homogeneity at 3T
  • ZOOMit powered by TimTX TrueShape - Zoomed imaging to see the details and making full use of parallel transmit
4G Speed
  • Easier and quicker set-up with improved Tim 4G DirectConnect and SlideConnect coils
  • Tim Dockable Table is mobility done right
  • iPAT3 allowing parallel imaging in two directions for fast data acquisition

DirectRF – fully digital design

Integration of all transmit and receive components at the magnet, enabled by the unique digital-in and digital-out design with fiberoptic cables between the magnet and equipment room.

  • Enabler for real-time feedback loops
  • Higher signal purity and improved stability
  • Enhanced image quality, less noise
  • Easier siting 

Real-time feedback loop

Dynamic feedback control of the RF transmit system for higher temporal stability and power linearity.

  • Exellent signal stability
  • Accuracy and stability in transmission 
Maximum of 84 coil elements in FOV with MAGNETOM Prisma and Head/Neck 642

Tim 4G coils

Tim 4G’s wide coil portfolio includes ultra-high channel coils and enables highest coil element density.

  • Designed for excellent SNR and speed
  • Designed with patient comfort in mind
  • Designed for optimized ease-of-use 

Dual-density signal transfer

Signals from two different coil elements can be sent with different frequencies on a single wire, unlocking the potential for higher density coils. The signals are separated again in the receiver to enable a unique 1-to-1 element /channel relationship.

  • Less signal interference, greater robustness
  • Higher SNR
  • Less and thinner cables enable easier handling of high-channel coils

The precision of Tim 4G enables you to achieve excellent image quality and speed in MRI.

Fast, high-resolution imaging 

enables Siemens unique applications such as CAIPIRINHA for ultra-fast breath holds or TimCT (Continous Table move) for a smooth workflow for large Field of View applications.

Larger and more flexible coverage

Up to 204 coil elements can be used in combination with up to 128 RF channels.

  • The extensive coil portfolio offers extended coverage and more flexibility in scanning diverse body regions
  • Dual-Density Signal Transfer enables a higher number of coil elements, higher SNR and 50% fewer cables

“Siemens again succeeded in setting a new standard of imaging”
(in MSK imaging)

Professor C. Pfirrmann, MD
University of Balgrist, Zurich, Switzerland
Member of Advisory Board Orthopedic Diagnostics

"Our initial experience shows that the images are exceptional, and the handling of the system and the patient will make MRI diagnostics much more efficient in the future. Thus, this opens the horizon for further integration of cutting-edge scientific developments into clinical routine”

Professor Stefan Schönberg, MD
University Medical Center Mannheim, Germany
About MAGNETOM Skyra

"The Skyra is going to change the game again. … because of the way they’ve redesigned the magnet itself, the RF system, the coil technology. All of that combined has allowed us to increase our throughput, and improve, while increasing our throughput, our image quality”.

Bob Day
Chief Technical Officer
Zwanger-Pesiri Radiology, USA
