Overview

Precision DL is an innovative deep learning-based image processing software developed by GE HealthCare, and a key component of its Effortless Recon DL portfolio. It is exclusively available on the all-digital Omni Legend PET/CT system. The software leverages an advanced deep neural network, trained using thousands of images from multiple reconstruction methods, including Time-of-Flight (ToF), to deliver image quality benefits traditionally associated with hardware-based ToF reconstruction, but without the need for additional hardware investment. Precision DL is engineered to provide greater diagnostic confidence and improve patient outcomes by enhancing image quality, including increased small, low-contrast lesion detectability, improved contrast-to-noise ratio, contrast recovery, and quantitative accuracy.

The technology processes patient images for enhanced image quality, enabling clinicians to spot small lesions and support more precise and personalized care. It offers flexible reconstruction settings (low, medium, or high strength) to tailor results to specific clinical preferences and integrates seamlessly with the Omni Legend’s AI-enhanced workflow solutions.

What Physicians Need to Know

Key Capabilities
Deep learning image processing software for PET/CT, engineered to provide up to a 42% average increase in small, low-contrast lesion detectability. It improves image quality by enhancing Contrast-to-Noise Ratio (up to 28% average improvement) and Contrast Recovery (up to 11% average improvement), and boosts feature quantification accuracy by 14% on average. Precision DL delivers image quality benefits typically associated with hardware-based Time-of-Flight (ToF) reconstruction without requiring additional hardware. It offers flexible reconstruction with low, medium, or high strength settings to tailor results to clinical preference.
Clinical Utility
Enhances diagnostic confidence and helps improve patient outcomes, primarily used by nuclear medicine specialists, radiologists, and oncologists. Key applications include oncology (early diagnosis, staging, monitoring), cardiology, neurology (high-sensitivity imaging for new/short-life tracers), and theranostics. It enables faster scan times and lower radiation doses for patients due to enhanced sensitivity and image quality, helping to spot small lesions even with very low dose injections.
Integration Options
Exclusively available on the GE HealthCare Omni Legend PET/CT system. It works seamlessly with the Omni Legend's AI-enhanced workflow solutions, such as the AI-based Auto Positioning Camera. Precision DL is part of GE HealthCare's broader Effortless Recon DL portfolio, which includes deep learning solutions for MR, CT, and X-ray. Deployment is on-premise.
Compliance Status
CE marked and received US FDA 510(k) clearance as of May 30, 2023. It was designed under the Quality System Regulations of 21CFR 820 and ISO 13485.
Pricing Model
Enterprise model, typically licensed as a feature or upgrade for the GE HealthCare Omni Legend PET/CT system. Specific pricing is not publicly disclosed and requires direct contact with GE HealthCare.
User Experience
Designed to deliver incredibly clear images and greater diagnostic confidence. Its flexible reconstruction settings allow tailoring results to specific clinical preferences. The tool aims to make state-of-the-art imaging accessible and offers a streamlined, simple solution that enhances technologist efficiency, patient care, and helps reduce potential radiation exposure to medical staff.
Support Quality
GE HealthCare offers support via email, phone, and 24/7 assistance, as part of its comprehensive service for the Effortless Recon DL portfolio. GE HealthCare has extensive industry experience, spanning over 100 years, and a global workforce of approximately 50,000 employees.
Implementation Complexity
Deployment is on-premise and is exclusively integrated with the GE HealthCare Omni Legend PET/CT system. Its nature as an integrated software solution within GE's Effortless Recon DL portfolio suggests a streamlined implementation process within that ecosystem.
Evidence Base
Trained with thousands of PET images using multiple reconstruction methods, including Time-of-Flight. Clinical data with inserted lesions was used to demonstrate improvements in Contrast Recovery, Contrast-to-Noise Ratio, and quantitation accuracy. A clinical reader study involving board-certified radiologists assessed overall image quality and preferences. Non-clinical testing covered quantitation accuracy, contrast recovery, contrast-to-noise ratio, lesion detectability, and dose/time reduction. Studies show consistent improvements in image quality, with High Precision DL exhibiting superior contrast recovery.
Physician Tip

Leverage the selectable reconstruction strength (low, medium, high) to optimize image quality based on specific clinical needs and patient characteristics, particularly for subtle lesion detection or dose reduction protocols. Recognize that Precision DL provides Time-of-Flight-like image quality without requiring hardware upgrades, which can be beneficial for existing Omni Legend users. Utilize the enhanced small lesion detectability and quantitative accuracy for improved confidence in oncology staging, monitoring, and theranostics. Consider the potential for reduced radiation dose and faster scan times, which can improve patient comfort and throughput.

Precision DL is an integral software component exclusively designed for and available on the GE HealthCare Omni Legend PET/CT system. It is part of GE HealthCare's broader Effortless Recon DL portfolio, which aims for a consistent deep learning approach across multiple imaging modalities (MR, CT, X-ray). This tight integration ensures seamless workflow within the GE imaging ecosystem but means it is not a standalone solution or compatible with non-GE PET/CT systems.

Frequently Asked Questions

Precision Deep Learning (DL) can significantly enhance a physician's practice by improving diagnostic accuracy in medical imaging, such as X-rays, MRIs, and CT scans, and by analyzing ECGs for early detection of heart issues. It also aids in creating individualized treatment plans by analyzing genetic and clinical data, and can streamline administrative tasks through workflow automation.
The use of Precision DL in healthcare is primarily regulated under frameworks like Software as a Medical Device (SaMD), requiring adherence to guidelines from bodies such as the FDA and AMA. Crucially, it must comply with patient privacy laws like HIPAA, ensuring secure data handling and transparent communication about AI's role in patient care.
While Precision DL, a subset of AI, offers advanced capabilities in analyzing complex medical data, traditional machine learning (ML) algorithms and statistical models can also be employed. However, deep learning often excels in automatically learning intricate features from large, unstructured datasets, which can be a limitation for conventional methods.
The cost of implementing Precision DL solutions varies widely, from approximately $25,000-$75,000 for patient engagement tools to $150,000-$500,000 for diagnostic AI systems in medical imaging. These costs encompass development, extensive data preparation, regulatory compliance, integration with existing EHR systems, and ongoing model retraining and monitoring.
Key limitations include the need for vast amounts of high-quality, diverse data for training, and the 'black box' nature of some models, which can make their decision-making process difficult to interpret. Risks involve the potential to perpetuate existing healthcare disparities if training data is biased, and the inherent probabilistic nature of AI means it's not always 100% precise, raising concerns about accountability for errors.
Precision DL systems must integrate robust cybersecurity measures and adhere to strict data governance policies to protect sensitive patient information. Compliance with regulations like HIPAA is paramount, involving data encryption, access controls, and regular security assessments to prevent breaches and misuse.
Precision DL is designed to augment, not replace, a physician's intellect, offering tools to analyze data and provide insights that support clinical decision-making. Human oversight remains crucial, as physicians are responsible for interpreting AI recommendations within the context of individual patient needs and maintaining the humanistic aspect of care.
