Technical Principle
Clinical Benefits

Powered by cutting-edge deep learning technology, Ultra EFOV (Ultra Extended Field of View) redefines the boundaries of imaging—capturing the entire bore-size view with remarkable clarity. It unveils additional anatomical structures, enhances skin contour definition, and delivers seamless image continuity at the SFOV (Scan Field of View) edge — so you always capture what matters.

Ultra EFOV uses a deep learning model to learn the differences between high-quality, bore-size gold-standard images and simulated truncated images beyond the SFOV. With a training dataset of over 500,000 images, the model is capable of restoring missing anatomical details outside the SFOV, eliminating truncation artifacts, and delivering clearer, full field-of-view images.

Ultra EFOV maintains HU deviations within ±20 HU across the extended FOV range from 50 cm to 82 cm. Its deep learning-based model effectively compensates for HU drift at EFOV boundaries, enhancing the image quality of both soft tissue and bone.
