uEXPLORER®

The World’s First Total-Body PET/CT

JUMP TO

Born to Explore

The uEXPLORER is an ultra-high-resolution digital PET/CT with a 194cm axial PET field of view (FOV) that enables the entire body to be scanned in one bed position. The system offers total-body dynamic scanning, which enables ultra-low patient doses and produces ultra-high image resolution, changing the way whole-body PET/CT imaging has traditionally been performed. With total-body coverage and unprecedented sensitivity, uEXPLORER is able to capture dynamic changes to radiotracer distribution with ultra-high temporal resolution. Take healthcare applications and scientific research to the next level with uEXPLORER.

194 cm Axial FOV

Ultra-large coverage by 564,480 crystal elements.

176 cps/kBq System Sensitivity*

Unrivaled sensitivity for superior image quality.

*Measured with a 70 cm NEMA NU-2 phantom.

2.9 mm NEMA Spatial Resolution

Functional images with anatomical details.

91 Billion LORs

No radioactive sources are required for automatic daily QC, reducing radiation exposure to the operator. Periodic full QC supports both liquid 18F and solid 68Ge sources.

Innovation

194cm Axial FOV

564,480 crystal elements, unit-based design and gapless assembly achieve total-body coverage and minimize accumulative system error, bringing high spatial resolution and precisely fused images.

40 x Sensitivity Improvement

With 194 cm axial FOV, uEXPLORER is able to capture orders of magnitude more γ photons. The innovative cross coincidence technology enables signal acquisition across adjacent units, which gives 30 to 40-fold overall sensitivity boost over conventional PET/CT systems. Ultra-high and uniform sensitivity can now be achieved with the total-body coverage, covering all vital human organs.

Integrated-Light-Guide Digital Detector

SiPM technology increases photoelectric conversion efficiency to reduce signal loss, yielding vast improvements in image quality. Ultra fine microscopic crystals significantly enhance image resolution.

Fast Data Processing for Image Reconstruction

uEXPLORER applies a state-of-the-art hardware platform in combination with parallel data processing architecture for fast and high quality image reconstruction.

Benefits

Functional lmages with Anatomical Details

Ultra-high resolution and sensitivity.
High count statistics enables small voxel reconstriction.

Fast Total-body Imaging

The thyroid nodule with high uptake is clearly visible on scan as short as 30 seconds. The fast imaging improves patient comfort and reduces motion artifacts.

Imaging with Reduced Tracer Dose

0.2mCi tracer for a 100kg patient. Much lower dose (0.002mCi/kg) than the typical dose (0.08~0.15mCi/kg).

Imaging Tracer Distribution for Longer

Scanned at up to 6.5 half lives post injection.Potential to observe radiopharmaceutical distribution over an extended period of time.

Total-body Dynamic Imaging in One Single Bed

Clear visualization of tracer distribution throughout the entire body including blood/organs/tissues over time.

Possibilities

Improved Lesion Detection

Improved lesion detection of tumor micro-metastases.

Cell Tracking & Function

Efficacy evaluation of stem cell therapies and cancer immunotherapies*.

New Pharmaceuticals Development
