MotionFree

First-ever Digital Respiratory Motion Management

At a glance

No need for a gating device

Initiating MotionFree is as easy as selecting a protocol

Up to a 67% improvement

in lesion volume measurements¹

Avoid adding to patient setup time

Up to a 30 percent improvement in quantitation accuracy²

Improve the patient experience

Enable a reduction in total procedure times by up to 11 minutes³

With an easy-to-use, completely digital workflow, MotionFree is the new standard for PET imaging

Respiratory motion can affect your images in ways that you can’t always predict. It can hide small lesions, make staging for treatment difficult and lead to inaccurate SUV and volume measurements. Current solutions are cumbersome and take too long to set up, which means you have to pick and choose which situations to use it in. So, only a small percentage of overall procedures affected by motion receive the benefits of motion correction.

Clinical images

Clear the way for clear images

MotionFree makes it easy for you to keep motion artifacts from interfering with your PET images. Not only does it automatically clear away motion artifacts from every PET image, it also clears away all the workflow barriers that, until now, have made it difficult to get the corrections you want.

Improved lesion conspicuity with ⁶⁸Ga-Dotatate at low doses

Another dotatate exam, with relatively high BMI. Lesion detectability is better, as new lesions are seen with MotionFree when compared to conventional static image. Shape of the liver is sharper and better defined, as well.

Improved lesion conspicuity with ⁶⁸Ga-Dotatate

In this case, MotionFree detected significant respiratory motion from only a single bed. This saves time in comparison to a scan that utilized an external respiratory-correction device. Size and activity of lesions are enhanced with MotionFree respiratory motion correction, and different scan times using MotionFree provided comparable image quality, with both showing improved lesion detectability in the liver area compared to conventional technology.

Improved lesion detectability and flexible workflow

Beds 2-4 selected for motion screening. Only beds 3 & 4 triggered for respiratory motion correction. Retrospectively processed with Th=0 to additionally apply MotionFree to bed 2.

Features

Reassure yourself with MotionFree

The first-ever respiratory motion management solution that doesn’t include a gating device. It’s always actively monitoring respiratory motion in the background of every PET/CT procedure. When it detects an anomaly, it automatically modifies the scan and then integrates what it learns into the final image in real time.

Workflow

A seamless digital setup

Traditional gating devices are clunky, awkward and take up to 11 minutes to set up. Then, once you do finally get it set up, there is always a chance of signal or detection errors, which may lead to repeat exams. MotionFree completely eliminates all of these barriers with a seamless, deviceless experience. It’s one major benefit for you, your patients and your referring physicians and one less thing for technologists to worry about.

Comfort

Take a big weight off their chest

When your patients come in for a PET/CT scan, they’re already under enough stress without having a piece of hardware placed on their chest, or being asked to breathe in a certain way. With MotionFree, you can take that weight off their chest. You can also reduce the total procedure time by up to 11 minutes and give them the freedom to relax and breathe naturally. All while capturing the clearest images possible.

The new way to scan

Technology

The brilliant thing about MotionFree is that it’s always there, even when you don’t think you need it. It gives you the flexibility to choose which bed positions receive motion correction, but it’s always collecting and correcting respiratory motion data in the background.

Always collecting and correcting respiratory motion data in the background.

Even if you don’t have MotionFree selected for a particular bed position, you can always go back and use that data to construct a motion-corrected image. It works for any patient in any clinical situation. You can use it as part of your everyday imaging routine, or you can explore new indications with emerging tracers.

Keep a watchful eye on every breath

MotionFree actively monitors your patient’s breathing pattern using information from the PET coincidence stream.

Traditional gating devices track motion in a single location and direction at the surface of the body

MotionFree measures organ movement in three dimensions. That means it’s aware of even the smallest movements, which is important because every patient has a unique breathing pattern.

Watch animation

It makes informed decisions on the fly

Because MotionFree uses internal data, it automatically detects the effects of respiratory motion and makes real-time scan decisions about when to extend scan durations.

Its decisions are both quick and accurate

You’ll see up to a 30 percent improvement in quantitative accuracy²and up to a 67 percent improvement in lesion volume measurements¹.

Every correction is thought through to the end

By the time a scan is complete, MotionFree has everything it needs to eliminate motion artifacts from your PET images. It fully integrates all respiratory motion corrections into the final image reconstruction.

The end result being, you get the benefit of motion correction in every image.
