KinetiCor’s state-of-the-art in-bore 3D prospective motion correction technology delivers precision head pose tracking and correction in 6 Degrees of Freedom for the most rigorous of MR applications.
– Optimized for high field MR environments, the technology has been tested to 9.4 Tesla. Customized optics, electronics and enclosures minimize EMI and isolate the camera system for increased tracking accuracy.
– Based on a proprietary optical machine vision motion tracking technology, MR pulse sequences are updated in real-time through an API layer that provides precise pose coordinates to the MR scanner.
See with your own eyes the impact KinetiCor’s motion correction technology by taking a closer look at the uncorrected and corrected images below….it won’t take long to see that the difference is clear.
KinetiCor’s Prospective Motion Compensation system is currently for research purposes only and has not been approved or cleared for clinical use.

Despite continuous improvements in Magnetic Resonance Imaging (MRI) through advances in image quality and acquisition speed, all existing MR examinations are easily compromised by patient movements during a scan. Approximately one in five MRI scans are repeated because of poor image quality due to patient movement; costing the healthcare industry an estimated $2 billion annually.
Problems with patient motion are most often encountered when working with non-compliant patent populations, such as:
– children or infants
– trauma cases
– people agitated by anxiety or pain
– people affected by movement disorders such as Parkinson’s
In extreme instances, images are degraded to the point that they are rendered non-diagnostic or of low diagnostic value. Often, these costly scans need to be repeated, either in part or in their entirety. Sadly, often times patients that need a quality MR the most are the ones where obtaining a clear scan is the most difficult.
– Provide optimized image quality by reducing or eliminating motion-induced blurring and distortion and the potential for misdiagnosis or non-diagnostic exams.
– Reduce or eliminate the need for sedation in populations prone to movement during scans.
– Reduce the need for rescanning and callbacks, equating to an estimated $1 billion in annual healthcare expenses.
KinetiCor Prospective Motion Compensation Advantages
Major commercially available prospective motion compensation methods are relatively slow, offer limited motion correction, consume bandwidth away from scan acquisition and lengthen overall scan time.
Major retrospective motion correction methods also lengthen scan time, cannot correct for through-plane movements.
KinetiCor’s technology does not require any additional scan time, updates scanning parameters in real-time to correct for motion, and works for both 2D and 3D scans.
KinetiCor’s motion compensation technology allows for remarkably accurate scans, with correction for motion as small as normal breathing. Normal breathing accounts for head motion of ~500 microns, meaning KinetiCor’s technology is able to correct for motion and improve image quality in seemingly non-moving, cooperative patients as well as those that move substantially.
Prospective motion correction systems will have a profound impact on the quality and costs of clinical and research MR imaging. Significant savings will be realized by reducing the need to repeat scans and the need to sedate patients to reduce motion during scanning. This system is an extraordinary integration of real-time control of imaging sequences with a novel method for measuring motion. The system has demonstrated remarkable results that are likely to continue to improve with ongoing development.”

From the very beginning of the project back in 2003 we have believed that the prospective motion correction will revolutionize MRI, especially in non-cooperative subjects and patients. It’s been a long way though, until the tracking technology and the MRI methodology has matured to the present point when we were able to demonstrate its real benefits for the image quality. Interestingly, the prospective motion correction has in a way outperformed our expectations, as it not only effectively suppresses the artifacts for the cases with strong motion, but also improves high-resolution acquisitions when no apparent motion is present.”

I consider prospective motion correction technology a major break-through in MRI for clinical and academic applications. In diagnostic imaging it will reduce the number of repeat exams or non-diagnostic results, thus allowing better diagnosis and reducing healthcare costs. In addition, technical advances in MRI lead to ever increasing resolution of MRI images, demanding patients to hold extremely still. The full potential of high resolution imaging will only be unleashed with motion correction technology.”

Prospective motion correction will have a huge impact for clinical MRI. It is the patients who need MRI the most who also move the most during the scan – children or the elderly, or patients who have head trauma, dementia, Parkinson’s disease, or brain tumors. With potential cost savings on the order of $1 billion per year, MRI scans may eventually become less expensive and therefore more affordable, which means more people can benefit from an MRI.”
