What Is TIM in MRI and How Does It Differ from TIM + DOT?

When choosing an MRI system it can be difficult to decide what features and options you need. For example, you may wonder whether you want an MRI with Total Imaging Matrix (TIM) or a Daily Optimization Throughput (DOT) upgrade, or even both.

But, what is TIM in MRI and what is DOT in MRI?

TIM means that the MRI is fully digital and that it is optimized to create incredible images with top quality resolution. The DOT upgrade in MRIs is a feature meant to make everyday exams easier through personalization.

In this short and simple blog post, we explain the TIM and DOT systems in more detail. This is to ensure that you have the best conditions for choosing the right system for you. 

We walk you through everything from the benefits of these features to examples of great TIM and DOT MRI machines.

MRI Matrix Coils

When buying a TIM MRI, it is important to ensure that the machine has matrix coils as well. This is because matrix coils are what supports the TIM feature in such a way that together they provide high quality imagery. 

The matrix coils have many elements and a larger matrix. More elements essentially means that the system has more channels and thus more connectors. 

Overall, this means that there will be a higher density of pixels. This provides better spatial and temporal resolution. So, you get better image quality and SNR.

Remember that not all coils are TIM — that is, they are not all matrix coils. To get the full benefit of TIM you need a matrix coil. Thus, you need to be aware of your needs before purchasing your next system.

If you are interested in finding a TIM MRI, you can look into Siemens systems. All machines from Siemens from 2004 and up are total imaging matrix systems.

As we mentioned earlier, it is also possible to get your hands on an MRI machine that has been upgraded with DOT technology.

The Siemens Magnetom Avanto 1.5T and the Siemens Magnetom Essenza 1.5T MRI’s can both be manufactured with DOT, or be DOT upgraded. 

This means that both systems can be either upgraded from TIM to TIM and DOT, or they can come with both of these features.

Finally, there is another point to consider when looking for your next system. All DOT upgraded machines are TIM, however not all TIM machines are DOT upgraded. 

Of course, it is possible to get systems that have both features, you just need to keep an eye out for it to avoid any unfortunate situations.

Sum up

Now that we have gone over all the important points about ‘what is TIM in MRI?’ and ‘what is DOT in MRI?’, let us sum up.

  • What is TIM in MRI (Total Imaging Matrix)?

    This technology in Siemens MRIs is highly convenient for everyday operations thanks to its integrated coil system that allows you to easily do full-body scans in no time at all.

    This is because there is no need for repositioning of patients during exams.

    Also, you can be sure that the image quality in the TIM systems is impeccable, which further supports doctors in making confident diagnostics.

  • What is DOT in MRI (Daily Optimization Throughput)?

  • What MRIs have TIM and DOT features?

This rounds up this short blog post. Hopefully, now that you know the answer to what is TIM in MRI and what is DOT in MRI, you feel more prepared for your next MRI purchase.
