Shape your pulse. Shape your image.
TimTX TrueShape is Siemens’ architecture for parallel transmit. The aim of TimTX TrueShape is not to overcome hurdles at 3T such as dialectic shadings. For this, Siemens has introduced TrueForm technology as standard with all 3T scanners since 2007. The aim of TimTX TrueShape is to open up new clinical application fields for MRI. Thus, giving you as our customers, the possibility to broaden your clinical scope and serve more patients in a challenging healthcare economy.
You can see more detail in less time, broaden your clinical scope, and experience greater diagnostic confidence.
TimTX TrueShape can do more than just overcome 3T hurdles
At 3T, dielectric shadings can occur. This means RF distribution can vary according to different body areas and affect image quality. The solution to this problem is B1 homogenization or B1 shimming. Since 2007, Siemens has been offering an anatomy-specific B1 shimming solution as part of TimTX TrueShape, called TimTX TrueForm. This solution has proven itself more than 800 times. It significantly increases B1 homogeneity and thus image quality without additional scan time or a change in workflow. It is standard with MAGNETOM Spectra, MAGNETOM Verio, MAGNETOM Skyra, and MAGNETOM Prisma.
“TrueForm Design leads to increased homogeneity and image quality for all organs. It has made 3T MR imaging clinical routine.”1

TimTX TrueShape also includes a B1 shimming solution, but results have shown that its benefits lie elsewhere.
Patient-specific B1 shimming can be performed with TimTX TrueShape. For patient-specific shimming a B1 map needs to be calculated for each patient. This takes time and changes the scanning workflow. Several field tests have shown that, in most clinical cases, patient-specific B1 shimming provides the same result as TimTX TrueForm, a faster, anatomy-specific approach. The true clinical applications of parallel transmit technology lie beyond simple mitigation of dialectic effects at 3T.
Fully dynamic parallel transmit with TimTX TrueShape
TimTX TrueShape is the first platform in the MR industry to make full use of the dynamic capabilities of a parallel transmit array system. With TimTX TrueShape you are able to independently shape the RF pulse from multiple independent RF sources, to enable new MRI applications and open the door to new, hitherto unexplored, development and research opportunities.
Our first application based on the TimTX TrueShape platform is ZOOMit. By means of sophisticated “dynamic” RF pulses, you can excite a smaller FOV to image a select region specific to your application or clinical question. Broaden your clinical scope with images with greater anatomical details and higher diagnostic quality obtained in less time.
Significantly increased image quality in the zoomed area and shorter scanning times.
TimTX TrueShape enables ZOOMit
- Use syngo ZOOMit to highlight regions, organs, or even features of an organ
- Create an MRI zoom through selective excitation
- The first TrueShape application for clinical use
And, now with TimTX Acceleration2 ZOOMit is brought to a new level, providing 20%3 higher SNR.
“I couldn’t really believe that we are able to excite a smaller field-of-view without getting aliasing artifacts, so I was very impressed! This was great.”1

University Medical Centre, Mannheim, Germany
Collaboration is the key for innovative MRI technologies and applications. Based on Siemens’ large network of innovation partnerships, ZOOMit is the result of fruitful collaboration backed by the pTX architecture TimTX TrueShape. And this is only the beginning of the capabilities of parallel transmit technology. Let’s explore the limits together.
“Parallel transmit holds the promise that we can reduce artifacts in regions of the brain that are very hard to get with standard imaging sequences.”1
