Motion correction & quantitation accuracy

Improvements to two core pillars of PET/CT imaging

Built upon the strongest foundation of performance

While delivering high NEMA sensitivity and clinical NECR, Discovery IQ Gen 2 also provides improvements to two core pillars of excellent PET/CT imaging - motion correction and quantitation accuracy. MotionFree can provide every patient the benefit of reduced motion in their images, while more accurate quantitation tools will help produce greater image quality for better patient outcomes. Additionally, the re-engineered hardware enhances the technologist and patient experience.

Discovery IQ Gen 2 provides a great opportunity to invest in the world’s most trusted PET/CT platform for your molecular imaging requirements.


High sensitivity to meet your greatest needs

Discovery IQ Gen 2 reinforces what high sensitivity can do for your image quality. Built with a combination of high NEMA sensitivity, high clinical NECR, and outstanding field-of-view coverage, this PET/CT system has exceptional small lesion detectability.

Amongst these impressive capabilities, Discovery IQ Gen 2 also features Smart MAR, which helps reduce metal artifacts, providing significant reduction of streaks and shadows to save time from correcting images. It is imaging in the highest sense, using low dose and faster acquisition times to acquire high-clarity images.
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. As a result, only a small percentage of overall procedures affected receive motion correction. With MotionFree, Discovery IQ Gen 2 assures that every patient gets the benefit of reduced motion during their exams.

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

  • Up to a 30% improvement in quantitation accuracy (SUVmean) compared to non-motion corrected data2

  • Up to a 67 percent improvement in lesion volume measurements3

  • Avoid adding up to 11 minutes to patient setup time compared to an external gating device4
  • Quantitation

    Accurate data points to trusted treatment

    With Discovery IQ Gen 2, your quantitation is no longer limited by the technologies used to produce it. Compared to conventional methods, Discovery IQ Gen 2 uses more accurate and consistent quantitative tools like Q.Clear to support your treatment with precise data points. This allows your SUV measurement to become more than a number. It becomes a tool for trusted clinical discovery, diagnosis and treatment assessment.

  • Up to a 2x improvement in image quality (SNR)

  • Up to a 2x improvement in quantitative SUV (SUVmean)
  • Technology

    Detection at the speed of light

    Discovery IQ Gen 2 comes with the LightBurst PET Detector that reduces scan times and dose amounts in half 5. Combined with the next-generation improvements in sensitivity, motion correction and quantitation, you can expect increases in the image clarity, the speed that you acquire images and the confidence you have in seeing smaller lesions. We paired this innovative detector technology with the Optima™ CT540, which has the equivalent speed of a 50-slice CT with IQE 1.75 pitch booster6 to meet your imaging needs. The LightBurst PET Detector is compatible with advanced digital solutions designed to connect machines, people and data through a portfolio of healthcare analytics applications.

    Healthcare providers need a cost-effective system that has the flexibility to evolve with the demands of its users and accommodate for future growth. Discovery IQ Gen 2 is made for this. It is an accessible, mobile-ready platform designed with a fully-scalable detector ready to meet the clinical needs of all.

    A system designed around you and your patients

    The Discovery IQ Gen 2 improvements don’t stop with high-performance software upgrades. Now with a smaller footprint, Discovery IQ Gen 2 also offers hardware enhancements that may reduce radiation exposure to technologists and improves the user interface for exam reporting. Combined with the latest software upgrades, this allows for a better technologist and patient experience while enabling a powerful boost in PET/CT productivity and performance.


    Give technologists ability to landmark and position patient table from console room

    May reduce technologist radiation exposure and improve workflow⁷

    Table positioning and landmarking from the console

    Improved user interface

    Easy-to-use PET exam reporting and retrospective reconstruction

    Up to six minutes less radiation exposure per day⁸

    Up to two hours of reduced radiation exposure per month

    Up to 10 percent reduction in total scan time⁸

    Scan two more patients each day
    1. Based on PET/CT sales and installation industry data from 2014-2018.
    2. As demonstrated in phantom testing using a typical and fast respiratory model, 18 mm Ge-68 spheres and OSEM reconstruction. Quantitative accuracy improvements are based on SUVmean.
    3. Compared to non-processed (STATIC, no motion-correction) data. As demonstrated in phantom testing using a typical and fast respiratory model, 18 mm Ge-68 spheres and OSEM reconstruction.
    4. Based on clinical practice at University Hospital Zurich, using 5-ring PET/CT with MotionFree and RPM. These results are for illustrative purposes only and represent specific customer experiences; actual results could vary depending on clinical practice and circumstances.
    5. Comparing Discovery IQ Gen 2 5-Ring to Discovery IQ Gen 2 3-Ring
    6. IQ Enhancement (IQE) may reduce helical artifacts which are important for image quality of thin-slice helical scans. CT scanners with this feature can accelerate its helical pitch up to 70% (e.g. 0.562 to 1.75, @ 16 slice) when acquiring the same helical artifact level compared with the same scanner with IQ Enhance disabled. This coverage speed is equivalent to that of a 50-slice wider detector CT scanner at same table speed.
    7. AutoIN may minimize the radiation dose to technologist and time spent to position the patient from the scanning room.
    8. Based on results found at one Medical Evaluation site installation, Tata Memorial Hospital – India. Results may vary.
