Exceptional image quality

Get a clear picture with Aurora

Aurora attains exceptional levels of image quality and scan time with GE HealthCare's exclusive technologies Clarify DL and SwiftScan. Improvements in image quality can help reinforce diagnostic confidence.
Clarify DL

Refocus with Clarify DL and move on from reading around the noise

Image quality has always required a trade-off between removing noise and maintaining contrast. GE HealthCare has a solution that mitigates that trade-off. Clarify DL is Aurora's AI-enabled bone SPECT image reconstruction designed to reduce noise, while retaining signal contrast. Doing so improves contrast-to-noise ratio (CNR) and contrast recovery coefficients (CRC)⁴, which are important factors in lesion detectability. With or without CT, Clarify DL is designed to achieve a new level of image quality performance without having to increase injected dose or scan time. Improved image quality performance may help increase diagnostic confidence.⁵ Clarify DL’s image resolution has been rated as better in 98% of exams.⁶
SwiftScan SPECT

Enable scan time or injected dose reduction by up to 25% while maintaining lesion detectability⁷

SwiftScan SPECT technology combines an exclusive LEHRS (Low Energy High Resolution and Sensitivity) collimator with SPECT Step & Shoot continuous scanning mode to increase sensitivity for improved small lesion detectability⁸.
Evolution

Enable scan time or injected dose reduction by up to 50%⁹

Evolution, Aurora's resolution recovery algorithm, is designed to help overcome conventional NaI imaging trade-offs by modelling the collimator-detector response.

With its 40 mm detector, Aurora achieves twice the detector coverage compared to CTs of other hybrid systems.¹¹ Aurora's 0.35 second rotation speed¹² and 2X detector coverage open up your clinic to performing advanced cardiac procedures.

Aurora's Revolution Ascend expands your CT versatility

Beyond routine CT exams, such as low-dose lung screenings and calcium scoring, Aurora can perform advanced CT procedures like coronary CT angiography (CCTA) and multi-phase CT.

ASiR-V reconstruction using lower dose (up to 82% relative to FBP¹⁰)

This next-level iterative ASiR allows you to lower noise up to 91% at the same dose¹⁰ᵇ and improve spatial resolution up to 2.07X (107%) at the same image noise.¹⁰ᵇ

MaxFOV2 extends the display field of view (DFOV) from 50 cm to 75 cm¹⁴

When body size or positioning causes portions of the patient to extend outside the scan field of view, MaxFOV2's AI algorithm overcomes this, enabling the visualization of the patient's whole anatomy.

Smart MAR delivers excellent artifact-less image quality

Smart Metal Artifact Reduction is designed to help reduce photon starvation, beam hardening, and streak artifacts caused by metal in the body.

SnapShotᵀᴹ Freeze 2–automated intelligent whole-heart motion correction

The SnapShot Freeze 2 algorithm provides up to 6x improvement in motion blur reduction while maintaining high spatial resolution.¹³

Support for high BMI patients

Aurora accommodates a wide range of patient body types

Aurora’s 75 cm-wide CT bore opens up more space to high BMI patients for a comfortable scanning experience. The 75 cm CT display field of view with MaxFOV2 enables the visualization of high BMI patient's whole anatomy.¹⁴

Effortless Workflow

Streamlining from start to finish

Aurora is designed for efficiency, from pre-scan to post-scan. Enhanced by AI, automation and design innovations, it streamlines technologists' workflow, while ensuring a smooth and comfortable experience for patients.

Real-time Activity Curve

Monitor dynamic activity as it happens, gaining valuable insight into radiopharmaceutical uptake-to-clearance.

Extended hybrid imaging range flexibility

Extending the SPECT/CT imaging range out to 185 cm extends the range of patient body types that can be accommodated in the hybrid scanning. This added range allows easier patient positioning.¹⁵

Auto Prescription

Auto Prescription delivers an auto-adjustment of scan settings, balances dose and image quality, and generates reusable, customizable patient profiles.

Smart Plan

Smart Plan automatically provides a start/end scan location and DFOV suggestion for specific anatomies based on scout images to support head, chest, abdomen and pelvis scans.

Aurora brings simplicity to the technologist's day-to-day routine.

Whether it is the touch ruler, or easy and fast collimator exchange, or fast, extrinsic QC, Aurora eliminates unnecessary tasks, time and effort.

3. The statement by the GE HealthCare customer described here is based on their own opinions and experiences and on results that were achieved in the customer’s unique setting. Since there is no typical hospital and many variables exist, such as hospital size, case mix, etc., there can be no guarantee that other customers will achieve the same results.
4. Clarify DL improves contrast recovery coefficient (CRC) up to 82% and contrast to noise ratio (CNR) up to 58% as compared to use of GE bone SPECT factory reconstruction presets for dual head cameras.* CRC and CNR are important factors in lesion detectability. *CRC and CNR demonstrated using digital phantom with inserted lesions of known size, location, and contrast, for AC and NC images.
5. Clarify DL improves dual head cameras’ image quality performance measured by Structures Similarity (SSIM) – up to 8% improvement, Mean Squared Error (MSE) up to 76% improvement, and Peak Signal-to-Noise Ratio (PSNR) - up to 18% improvement, as compared to GE bone SPECT factory reconstruction presets*. Improved image quality performance may help increase diagnostic confidence. *Demonstrated using digital phantom simulations with inserted lesions of known size, location, and contrast, for AC and NC images.

In 127 exams rated by total of 9 physicians, in 98% of the exams, Clarify DL’s image resolution was rated as better than the existing factory reconstruction preset images.* *As demonstrated in clinical evaluation, where each exam was reconstructed with both Clarify DL and the existing factory reconstruction preset and evaluated by 3 of the physicians.
7. Compared to LEHR collimator, with Step & Shoot scan mode (for SPECT). As demonstrated in phantom testing using a bone scan protocol, Evolution processing (for SPECT), and a model observer. Because model observer results may not always match those from a human reader, the actual time/dose reduction depends on the clinical task, patient size, anatomical location and clinical practice. A radiologist should determine the appropriate scan time/dose for the particular clinical task.
8. As demonstrated in phantom testing using a model observer. Compared to using the LEHR Collimator and a SPECT Step and Shoot acquisition.
9. In clinical practice, Evolution Options [9a] (Evolution for Bone, Evolution for Cardiac, Evolution for Bone Planar) and Evolution Toolkit [9b] are recommended for use following consultation of a Nuclear Medicine physician, physicist and/or application specialist to determine the appropriate dose or scan time reduction to obtain diagnostic image quality for a particular clinical task, depending on the protocol adopted by the clinical site.
9a. Evolution Options–Evolution claims are supported by simulation of count statistics using default factory protocols and imaging of 99mTc based radiotracers with LEHR collimator on anthropomorphic phantom or realistic NCAT–SIMSET phantom followed by quantitative and qualitative images comparison.
9b. Evolution Toolkit–Evolution Toolkit claims are supported by simulation of full count statistics using lesion simulation phantom images based on various radiotracers and collimators and by showing that SPECT image quality reconstructed with Evolution Toolkit provide equivalent clinical information but have better signal-to-noise, contrast, and lesion resolution compared to the images reconstructed with FBP/OSEM.
10a. ASiR-V reduces dose by 50% to 82% relative to FBP at the same image quality (Image quality as defined by low contrast detectability.)
10b. In clinical practice, the use of ASiR‐V may reduce CT patient dose depending on the clinical task, patient size, anatomical location, and clinical practice. A consultation with a radiologist and a physicist should be made to determine the appropriate dose to obtain diagnostic image quality for the particular clinical task. Low Contrast Detectability (LCD), Image Noise, Spatial Resolution and Artifact were assessed using reference factory protocols comparing ASiR‐V and FBP. The LCD was measured using 0.625 mm slices and tested for both head and body modes using the MITA CT IQ Phantom (CCT183, The Phantom Laboratory), using a model observer method.
11. As compared to NM/CT 870 DR with Optima 540 CT.
12. 0.35 rotation speed is optional. 0.5 second rotation speed is standard.
13. This is demonstrated in cardiac phantom testing. The reduction in motion artifacts is comparable to a 0.058s Equivalent Gantry Rotation Speed with effective temporal resolution of 29 msec, as demonstrated in mathematical phantom testing.
14. The image quality for the area outside the standard 50 cm scan field does not meet the image quality specifications shown in the technical data sheet and image artifacts may appear, depending on the anatomy scanned.
