Precision DL is an innovative deep learning (DL) 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.
Key Benefits and Capabilities:
Precision DL is engineered to provide greater diagnostic confidence and improve patient outcomes by enhancing image quality. It achieves this through several key performance improvements:
- Enhanced Small Lesion Detectability: Provides up to a 42% average increase in small, low-contrast lesion detectability.
- Improved Image Quality: Offers an average improvement in Contrast-to-Noise Ratio (CNR) and Contrast Recovery (CR), with reported improvements of up to 28% and 11% respectively.
- Quantitative Accuracy: Improves feature quantification accuracy by 14% on average.
- Flexible Reconstruction: Allows clinicians to choose from low, medium, or high strength settings to tailor the result to their specific clinical preference.
- Workflow Integration: Works seamlessly with the Omni Legend's AI-enhanced workflow solutions, such as the AI-based Auto Positioning Camera, to improve operational efficiency and patient throughput.
Target Users and Use Cases:
Precision DL is primarily used by nuclear medicine specialists, radiologists, and oncologists in enterprise-level hospitals and imaging centers. Its primary use cases span multiple clinical areas, including:
- Oncology: Enhancing the ability to spot small lesions for early diagnosis, staging, and monitoring of cancer.
- Cardiology & Neurology: Providing high-sensitivity images for procedures involving new and short-life tracers.
- Theranostics: Supporting the diagnostic portion of combined diagnostic and therapeutic interventions.
- Dose Reduction: The enhanced sensitivity and image quality allow for faster scan times and lower radiation doses for patients.
