Compressed SENSE
Up to 50% faster MRI scans with virtually equal image quality1
How does Compressed SENSE work?
Compressed sensing is a signal processing technique built on the fact that signals contain redundant information. Watch how in MRI this technique is used to reconstruct a full image from severely under-sampled data (in k-space) while maintaining virtually equivalent image quality.

Features
Increase productivity
If you are looking for ways to increase the utilization of your MR equipment to meet the rising demand for MRI services, Compressed SENSE can be the answer. A full MRI exam performed with Compressed SENSE, for example, can save minutes compared to a conventional MRI. This could free up one or two extra exam slots in your daily schedule, which can result in much higher productivity and shorter waitlists without adding more operator hours.
Reduce scheduling hassles
With Compressed SENSE you can create a buffer to easily handle emergency cases or urgent patients that are referred on the same day. This extra capacity can help you serve patients and referring physicians faster and make daily workflow go smoother for your staff.
Extra time for patients
Most patients approach their MRI exam with a certain level of apprehension or fear of closed spaces that can cause delays and poor results. Compressed SENSE shortens MRI scan times, so your staff can give patients extra attention and reassurance. They can explain what to expect and how to comply with the instructions they receive. This extra personal attention can promote a positive scanning experience, which can build your reputation as a patient-friendly MRI provider.
Shorter breath holds improve patient experience
If many of your patients have difficulty holding their breath during an MRI exam, it can have a big impact on your failure and re-take rates. That can have a knock-on effect across your entire schedule. Compressed SENSE can reduce breath hold times by up to 40%, with virtually equal image quality.1 Hospitals that have implemented Compressed SENSE report a better patient experience thanks to shorter breath holds.
Improve resolution for challenging anatomies
Obtaining high resolution scans can be very time-consuming, so they are difficult to accommodate in a busy department. Patients who are seriously ill or experiencing pain may also have trouble completing these long scans. In fact, Compressed SENSE enables up to 64% improvement in spatial resolution, within the same scan time.1
Create space for more powerful sequences
Thanks to the diversity of 2D and 3D MRI techniques, you can obtain a wealth of information about each individual case if you just have enough time. Compressed SENSE can give you the time and critical details you need to make confident decisions. For example, to obtain high spatial resolution of tiny nerves and vessels for brain and spine examinations, you can now replace 2D MRI scan sequences with faster 3D sequences. Compressed SENSE also gives you room to add extra routine and functional sequences to deepen diagnostic confidence.

“We used to do 2D scans and then you are bound to the imaging plane that was acquired. Now we do 3D imaging of the pelvis, isotropic imaging, and this then enables offline reform adding at any angle that you wish for, so this really helps.”

Frequently asked questions
- What is the technique compressed sensing?
-
Compressed sensing is a signal processing technique built on the fact that signals contain redundant information. Compressed sensing was developed by David Donoho3, while in the same period Emmanuel Candès, Terence Tao et al.4,5 showed the same principles. The initial evidence that image data can be compressed comes from digital photography. The realization that image compression was possible without loss of detail led to the intriguing question of whether this could be turned around: If all the data is not needed to store the relevant information, why should it be acquired?
- What are the clinical benefits of Philips Compressed SENSE?
-
Compressed SENSE creates opportunities to increase productivity, to increase precision and to enhance patient experience.
Compressed SENSE enables acceleration by up to 50% with the same resolution and virtually equivalent image quality as dS SENSE scanning. The time saved can boost productivity by enabling more patients per day.
Compressed SENSE can be used to create images with higher resolution in the same scan time that is currently allotted for exams to increase diagnostic confidence.
Compressed SENSE reduces the time spent in the MR for the patient.
