GE HealthCare has obtained FDA 510(k) clearance for True Definition DL, a deep learning–based image reconstruction technology designed to improve spatial resolution in CT.

The tool is intended to support high-resolution imaging across applications including pulmonary, musculoskeletal, and inner ear exams.

True Definition DL uses a dedicated neural network to enhance image detail while reducing artifacts. The approach aims to address long-standing trade-offs in CT imaging, where higher resolution has typically required increased radiation dose, longer scan times, or limited coverage. According to GE HealthCare, the system enables high-resolution imaging of structures such as small airways, pulmonary nodules, and trabecular bone without compromising acquisition speed or dose efficiency. The technology also supports a 1024 matrix display and can produce chest images in under one second.
“Image quality matters in healthcare; because when imaging performance is aligned with the specific diagnostic task, it plays a critical role in improving accuracy, enabling earlier detection, and guiding appropriate patient care,” said Chad Rowland, executive director, global premium CT and photon counting, GE HealthCare.

The clearance comes as demand for diagnostic imaging continues to grow alongside rising rates of chronic disease. Imaging volumes are increasing globally, placing pressure on radiology departments to deliver faster exams while maintaining diagnostic accuracy. Deep learning reconstruction methods have gained traction as a way to improve image quality and processing speed compared with traditional techniques.

True Definition DL builds on the company’s earlier deep learning offerings, including TrueFidelity DL and True Enhance DL. Those technologies focus on noise reduction, image texture preservation, and contrast enhancement in both single- and dual-energy CT imaging.

Dr. Stefanie Bitschnau, a radiologist at Radiomed, said the added resolution may support evaluation of small anatomical structures. “In chest imaging, this level of detail is particularly valuable for assessing small airways, supporting earlier and more confident evaluation of interstitial lung disease,” she said.

GE HealthCare said the new tool will be available on its Revolution Apex and Revolution Vibe CT platforms, including both new systems and upgrades.
