New Platform

The one and future PET/CT platform

As a worldwide leader in PET/CT, we are constantly innovating new ways to empower you to make this life-saving technology more helpful for more patients. Given the rapidly changing healthcare landscape, the time has come for an all-new PET/CT platform designed to surpass both your clinical challenges today, and well into the future. We call it Omni because its potential is limitless and we believe it is the future of PET/CT. Every component of Omni is entirely new. It was built on a foundation formed by decades of longstanding technological leadership and clinical collaborations with a wide array of innovative enhancements incorporated at every aspect of the scan experience.
Over the next 10 to 20 years, we see two great needs in PET/CT. The flexibility to scan beyond FDG with new, emerging tracers that can enable different procedures such as the diagnostics portion of theranostics imaging and the capability to accommodate increasing patient volumes. These needs require unprecedented levels of flexibility and capability, allowing you to determine which direction to grow your practice. In order to grant that greater freedom for your team both now and in the long run, we have designed a PET/CT platform with the future in mind.
Not only does Omni feature today’s innovative technology engineered by the team that built the most trusted systems in the industry, its scalable design uniquely positions the platform for future developments in the field of PET/CT imaging. Future-ready capabilities include a multi-directional, upgradable platform design that can possibly expand in each of the core dimensions of PET/CT imaging, including axial field-of-view, digital detector technology, software, CT capabilities and imaging of new tracers.

Technology

See it all. In an all-new digital light.

As PET/CT continues to grow into clinical areas outside of oncology, the need for a PET/CT solution that makes the power and possibility of digital detection more ubiquitous and accessible becomes increasingly more important.

We built Omni Legend from the ground up to harness the power of digital dBGO, an innovative detector material with a small crystal size capable of producing high resolution images and exceptional image quality. This creates a brand-new category of detector technology that delivers more than two times the sensitivity than prior digital scanners,4 enabling fast scans5 at a lower dose.6 The end result is a remarkable design that’s more accessible to more people today and with a detector assembly engineered for future upgrades that allows for axial field-of-view scalability up to 128 cm.

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

This changes everything

The detector material at the core of the Omni Digital Detector takes PET/CT to the next level. Its high density and stopping power along with a 30 mm crystal depth make it possible to achieve an astronomical increase in NEMA sensitivity with up to 46 cps/kBq across a 32 cm axial field-of-view.4 This extreme rise in sensitivity goes beyond just providing for a higher quality image. Along with an exceptionally high NECR curve, it’s what may enable you to image high count rate tracers beyond FDG with the potential to increase the number of procedures your staff can execute, including procedures beyond oncology such as cardiac and neuro imaging.

Software

Enhance your imaging with deep learning

The technological advancements achieved by Omni Legend don’t stop with the hardware. Omni Legend is all-digital and uniquely designed with innovative Precision DL* technology.
More than a new processing technique, Precision DL* is engineered with a sophisticated deep neural network trained on thousands of images made with multiple reconstruction methods. The intent is to provide the image quality performance benefits most associated with hardware-based Time-of-Flight, better contrast-to-noise ratio and contrast recovery7. This combination of Precision DL* and the digital dBGO-based Omni Digital Detector’s ultra-high sensitivity inside Omni Legend enables our vision for the future of PET/CT image quality.
Omni Legend takes the possibilities of Precision DL* even further because it also includes Q.Clear image reconstruction technology (BSREM) and MotionFree, our proven, deviceless respiratory motion correction technology. Q.Clear helps to ensure reliable quantification, while MotionFree operates seamlessly in the background to correct respiratory motion artifacts for all patient types.
All in all, Omni Legend utilizes breakthroughs in deep learning designed to help deliver clearer images and greater diagnostic confidence. And this is all designed to be accomplished with deep learning software. There is no longer a need to invest in hardware to deliver the image quality performance characteristics of Time-of-Flight. With Precision DL*, you get software engineered to provide increased small, low-contrast lesion detectability compared to our conventional Time-of-Flight PET/CT scanner.8
PATIENT EXPERIENCE

Surroundings they can take comfort in

We recognize that patient comfort is important to you. It’s a top priority for us too, which is why we are always looking for new ways to improve the overall PET/CT patient experience. 
 
 
 

We’ve learned that often it’s the little things that make the biggest difference. Like a simple visual distraction or a subtle lighting effect.

With Omni Legend, we’ve added an array of new features to make the scan as relaxing as possible for patients. The system features LED ambient lighting to help create a calming mood as well as a graphic pattern on the upper area of the bore to help in both alleviating stress and reducing movement for nervous patients. These seemingly small details can have a huge impact on improving the patient experience.
One patient who was previously scanned on Omni Legend came back two months later for her next follow-up PET scan and asked if she can have it done on the new system because she knew it would be faster and more comforting with the ambient lighting.⁹
Workflow

Full speed ahead

Operational efficiency continues to be a top barrier to growing PET/CT procedure volumes.10 Omni Legend overcomes this barrier with a collection of intuitive workflow solutions enhanced by AI.
Our innovative Auto Positioning feature creates a hands-free positioning experience by generating a 3D model of the patient’s body, pinpointing the center of the scan range using a deep learning algorithm and automatically aligning it with the isocenter of the bore. With one click, Auto Positioning streamlines patient setup, and most importantly, frees up technologists to focus on making your patients feel more comfortable.
Additional time-saving features include a fast data quality assurance process that saves time with streamlined calibration as well as simplified protocol selection on the gantry touchscreen and a new user interface to enable an easy PET/CT process from start to finish.

Ultra-fast whole-body imaging

The high sensitivity of the Omni Digital Detector combined with a large field-of-view can enable ultra-fast routine whole-body imaging.
