Digital PET that’s everything we promised. And more.

The promise of digital PET is precision across the entire imaging experience. Discovery MI has been delivering on that promise for years with one of the highest NEMA sensitivities of any ToF PET/CT system in the industry. This premium PET/CT also brought you clearer images with our MotionFree digital respiratory motion management solution and the accurate quantitative measurements of Q.Clear. Now, with Discovery MI Gen 2, we are taking the promise of digital PET even further. As the next generation of the world’s first digital PET/CT, Discovery MI Gen 2 will allow you to image and see even more. With a scalable FOV capable of an impressive 30 centimeters of digital detection coverage, this system delivers an exceptionally high sensitivity of 30 cps/kBq. Further enhancements include a CT designed to allow TrueFidelity deep-learning image reconstruction to enable image sharpness and improved noise texture¹. Additionally, AutoIN is our remote landmarking and table positioning feature that helps reduce your technologists’ exposure to radiation by allowing patient positioning from the console. The goal of Discovery MI Gen 2 is clear: to provide you with a premium digital PET/CT capable of enabling the next generation of clinical applications, so you can continue pushing the boundaries of your research and your clinical work.

DIGITAL DETECTORS

Digital detection, remastered

The LightBurst Digital Detector is a key component of what made Discovery MI the leading digital PET system. This innovative digital PET detector technology combines a small lutetium-based scintillator crystal array with a Silicon Photomultiplier (SiPM) block design for significant improvements in sensitivity, scan times, and required dose levels compared to similar ToF technology. Discovery MI Gen 2 provides next-level digital detection with an axial FOV scalable up to 30 centimeters and the corresponding potential to reach even greater levels of sensitivity.

SENSITIVITY

What does one more detector ring give you? A whole lot.

Not every PET detector ring is built the same. Each row of the Discovery MI Gen 2 LightBurst Digital Detector adds five centimeters to your total field of view, unlocking another layer of capability and performance. With the option to scale from 15 centimeters of coverage all the way up to 30 centimeters, you can expect the flexibility needed to decide how best to meet your immediate clinical needs, while also protecting your investment for the future.

Focus on what is most important.
High sensitivity per cm.

In PET imaging, sensitivity is everything. It affects your ability to detect small lesions, your scan length and dose amounts. Discovery MI Gen 2 can expand all the way up to 30 centimeters of coverage, providing a 50 percent increase in peak NECR³, as well as exceptional system sensitivity that reaches 30 cps/kBq. Ultimately, this translates to a system that delivers significant improvements in scan times or dose amounts.

WB Dynamic IQ Protocol

A whole new way to scan

Static whole-body PET/CT imaging provides a simple snapshot of radiopharmaceutical concentration, but to truly understand how tissue is behaving, you have to account for time. With whole-body dynamic imaging, you can see the difference between tracer activity that’s simply trapped in tissue versus highlighting actual malignancies. However, capturing this level of information takes time. Discovery MI Gen 2 delivers the FOV and the sensitivity necessary to enhance whole-body dynamic acquisition. It allows you to capture as much detail as possible in fewer bed positions. With Discovery MI Gen 2 and WB Dynamic IQ Protocol⁴, you have a powerful new tool that provides you with the ability to better identify regions of metabolic activity and increased tracer uptake rate⁵.

DIAGNOSTIC CT

See precisely what you need to see

​

Revolution™ EVO Gen 3 brings the precision of diagnostic CT to digital PET. Clearly see details as small as 0.28 millimeters with the enhanced spatial resolution of the Clarity Imaging Chain. Work around metal implants by virtually eliminating streaks and shadows from metal artifacts with Smart MAR. Then, take your CT experience even further on a system designed for TrueFidelity, our latest innovation in CT image reconstruction technology that uses a deep-learning based reconstruction engine to combine the low-dose CT you expect with the image texture you want.

TrueFidelity

For years, low dose was the benchmark for image quality by which every CT image was held. We helped set the standard for low-dose imaging back in 2008 by introducing the industry’s first iterative reconstruction technology capable of lowering dose. Over the years, the benchmark has changed. While dose is still important, radiologists are looking for an image texture reminiscent of the text-book quality images they studied in medical school. To that end, we’ve introduced Deep Learning Image Reconstruction, what we feel is the future of image quality. It uses artificial intelligence to combine the low dose of iterative reconstruction with a “classic-looking” image texture.

A CT that keeps getting better

TrueFidelity is available through Smart Subscription, the industry’s first subscription-based service for advanced applications. Smart Subscription helps solve the oldest challenge with buying imaging equipment: every time you buy a new system, you’re locked in to its capabilities even as new capabilities become available. Smart Subscription overcomes this challenge by making it possible to automatically keep your system up to date. So, for the first time, you can expect your hybrid CT to keep improving for as long as you have it.

EXPERIENCE

Plan on making an entrance by leaving the room

​

AutoIN gives your technologists the ability to landmark and position the patient table from the console in the control room. This improves the imaging workflow. By keeping technologists at the console, AutoIN helps reduce exposure to radiation as well as limits contact with contagious diseases.

MOTION CORRECTION

Clear the way for clear images

Respiratory motion negatively affects about half of all PET/CT procedures. Current gating solutions are cumbersome and take too long to set up, which puts you in the difficult position of having to pick and choose which situations to use it in. As a result, only a small percentage of overall procedures affected by motion receive the benefits of motion correction. However, with MotionFree, Discovery MI Gen 2 assures that every patient gets the benefit of reduced motion during their exams for exceptionally clear images.

MotionFree

MotionFree is the first-ever digital respiratory motion management solution that completely eliminates the need for a gating device. It continually monitors respiratory motion in every PET/CT procedure, and when it detects an anomaly, it automatically modifies the scan and then integrates what it learns into the final image in real time. MotionFree is the new standard for PET imaging and an essential tool for better outcomes.

QUANTITATION

Accurate data points to trusted treatment

Imagine a system that has everything you’ve come to expect from the most advanced digital PET, including quantitative accuracy. With Discovery MI Gen 2, you can. Our plan for Discovery MI Gen 2 is to no longer limit your quantitation by the technologies used to produce it. By using quantitative tools, like Q.Clear, that are more accurate and consistent compared to conventional methods, this system is designed to support your treatment with precise data points. What this means is your SUV measurements are able to become more than just a number. They become tools for trusted clinical discovery, diagnosis and treatment assessment.

Q.Clear

Since its introduction, Q.Clear (BSREM) has delivered fast and efficient quantitation readings for confident diagnosis and precise treatment response assessment by providing up to two times improvement in both PET quantitation accuracy (SUVmean) and image quality (SNR). For this reason, Q.Clear is a critical component of Discovery MI Gen 2.

​

A new generation of digital PET

Discovery MI Gen 2 is designed for a new generation of digital PET imaging. Our goal is to expand your clinical perspective with up to 30 centimeters of coverage, system sensitivity of up to 30 cps/kBq, trusted Q.Clear quantitation, and the proven clarity of MotionFree images. By combining next generation digital PET technology with an efficient technologist experience and the potential for deep-learning based CT image reconstruction, the promise of the digital PET experience is stronger than ever.
