HyperSense for high definition in a fraction of the time. Images acquired on SIGNA Architect.
To develop HyperSense, the researchers and engineers in GE Healthcare’s labs used an imaging technique that has been in the MRI research community for about ten years. Compressed Sensing (CS) as it’s called allows for an enormous acceleration of data acquisition in MR, but it had yet to be leveraged in this way for reduction of scan time or increased resolution.“Think of it like acquiring one piece of a larger puzzle. From that one piece, you can make assumptions about what the other pieces would look like so you can understand what the image is before the puzzle is complete,” said Atkins. “The neighboring pieces are likely to look similar. Therefore, by gathering multiple puzzle pieces (or raw data) you can put the whole puzzle together much faster.” [caption id="attachment_11105" align="alignnone" width="690"] HyperSense, the innovative software application, can be applied to most 3D applications for sequences in the brain, head & neck, spine, MSK, abdomen and pelvis[/caption] Faster scanning for patients means less time in the scanner. It also can help improve efficiency for clinicians and hospitals. With the pressures in the current healthcare environment, effective use of scanners can have significant savings. Oftentimes with new imaging techniques, quite a bit of extra training is required to ensure those operating the scanner know how to properly use the new technique. “Our techs love it, the software is very easy to use and doesn’t require a lot of extra thought or training,” comments Atkins. “There are constantly new [MRI] sequences and the physics of MRI is fascinating,” said Atkins. “I’m an MR person so I’m biased but it’s such a fantastic technology that can be so powerful. As we can image faster, [MRI] is going to only get better.” To date, over 10,000 exams have been conducted on HyperSense around the globe since it was introduced at the end 2016 and the number rapidly grows every day. **HyperWorks by GE Healthcare is a grouping of purchasable imaging applications (HyperSense, HyperCube and HyperBand) which can deliver higher spatial resolution images or reduced scan times on all body parts. 1.
