ZOOMit powered by TimTX TrueShape

ZOOMit is the first clinical application for parallel transmit technology. Powered by Siemens' parallel transmit architecture, TimTX TrueShape, ZOOMit uses dynamic excitation pulses to achieve selective field-of-view (zoomed) imaging, without aliasing artifacts. Imaging is faster, with less susceptibility artifacts and geometric distortions. Zoom into your image to appreciate the smallest details, to improve diagnostic confidence and expand research possibilities.

 With ZOOMit, you can: 

  • Image only your selective volume of interest; 
  • achieve faster, higher-resolution imaging,with less susceptibility artifacts and distortions; 
  • Gain additional 20% SNR1 with TimTX Acceleration2
  • Detect and evaluate smaller lesions, especially in areas prone to susceptibility artifacts, for increased diagnostic confidence, 
  • Broaden the scope of clinical MR imaging 
  • Unlock the door to new research opportunities.

Features & Benefits

With ZOOMit you can zoom into the anatomy and shape your image according to the region of interest. This enables the highlighting of regions, organs, or features of an organ.

Overall benefits of the the parallel transmit application ZOOMit

  • Increase in diagnostics confidence
  • Open up new MR imaging fields
  • Expand research possibilities
  • And, now with TimTX Acceleration2 ZOOMit is brought to a new level, providing 20% higher SNR1


ZOOMit is currently enabled for DWI, BOLD and T2 SPACE 3D imaging. 3D imaging like MSK, spine or brain profits the most from the ZOOMit induced scan time reduction. Diffusion based imaging profits from the significantly increased image quality.

ZOOMit can dramatically reduce scan time.In this comparison between conventional and zoomed imaging, scan time is reduced by 45% while maintaining the same high resolution.

Quality of DWI is especially crucial when this technique is used for the
detection of smallest lesions of high susceptibility (e.g.skull base, spine, abdomen, pelvis), or when quantification of diffusion restriction is required.

ZOOMit gives exactly that:
Significantly increased image quality in the area of interest. In this example of an MR diffusion in the prostate, the zoomed images have much less distortion and better delineation of tumor borders.

“The conventional DWI sequence in the Head & Neck is very challenging. With TimTX TrueShape, we achieve the same spatial resolution but with shorter echo trains – so we have less distortions.”3

excitation stripe

It is a well-known phenomenon in MR imaging that if the field-of-view (FOV) is smaller than the object, aliasing (foldover artifacts) will occur. This is not an issue in the readout direction, since it can be overcome by frequency oversampling. But oversampling in the phase-encoding direction comes at a cost: longer scan times. This makes the use of phase oversampling unfavorable or impossible in many cases.

With ZOOMit, similar to an optical zoom of a camera, only a reduced FOV in phase-encoding direction (‘stripe’) is excited (see figure below). Consequently, there will be no signal from the non-excited regions and only the small stripe needs to be encoded.
The result: Acquisition time can be reduced while maintaining spatial resolution, or the spatial resolution can be increased - or a combination thereof.

TimTX TrueShape

ZOOMit is based on TimTX TrueShape, Siemens’ architecture for parallel transmit (pTX) technology. This technology uses two indepedent transmit channels for fully dynamic RF excitation. Only TimTX TrueShape and ZOOMit together provide selective excitation within a user specified FoV. TimTX TrueShape is designed to break ground for a broad range of new MRI applications. ZOOMit is the first TrueShape application.
