TimDeliver exceptional quality and speed in MRI. With Tim.

AllCoilsOff

In 2003, Siemens launched Tim integrated coil technology, changing MRI forever. Featuring excellent image quality and fast acquisition speed, this proven technology has been installed over 9000 times to date. Tim's extended coverage means no repositioning for multiple exams, and more exams per day.
The newest generation - Tim 4G - is setting new benchmarks.

Delivering 4G Flexibility, 4G Accuracy and 4G Speed.

  • Up to 204 coil elements. Up to 128 RF channels.
  • Exceptional SNR and image quality with high channel coils and the unique RF architecture enabling DirectRF for true signal purity.
  • Excellent image quality with up to 40%1 reduced scan times. 
4G Flexibility

4G Flexibility

  • Up to 204 coil elements with up to 128 independent RF channels for higher SNR and speed
  • 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

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

4G Speed

  • Easier and quicker set-up with improved Tim 4G DirectConnect and SlideConnect coils
  • Tim Dockable Table is mobility done right
  • iPAT2 allowing parallel imaging in two directions for fast data acquisition

All digital-in/digital-out. With MAGNETOM.

Features & Benefits

Tim 4G's unique architecture:
The only fully digital MRI.

Tim 4G systems deliver exceptional image quality by optimizing the entire signal chain. The integrated coil technology is more than just high-channel coils – it is a completely digital RF architecture with a unique DirectRF design.

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 64

Tim 4G coils

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

Clinical Benefits

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

MRI - Technologies - Tim - Patient Comfort

Patient Benefits

Tim 4G ensures patients enjoy the most comfortable scan experience.

Maximized patient comfort:

  • Tim 4G coils are light weight and flexible in use for increased patient cooperation and satisfaction.
  • Patient-friendly coil design (e.g. “holes” in the Body 18 coil for breathability)
  • Innovative open design makes it easier to handle immobile patients
