– Faster image availability enables radiologists to review and interpret QTI breast scans more quickly, supporting earlier clinical decision-making –

– Image fidelity and diagnostic accuracy improvement, in addition to the significant processing speed gains –

QT Imaging Holdings, Inc. (OTCQB:QTIH), a medical device company engaged in research, development, and commercialization of innovative body imaging systems, is pleased to announce its latest image reconstruction software update release, version 4.4.0, which delivers a substantial reduction in the QTscan™ image processing time, improving user throughput and overall efficiency. The software update was developed leveraging NVIDIA’s L40 GPU, powered by the Ada Lovelace architecture.

The U.S. FDA-cleared QTI Breast Acoustic CT™ scanner is the first non-invasive breast imaging technology that provides a true 3D image of the breast anatomy without compression, contrast administration, or harmful ionizing radiation. Despite the processing speed gains achieved via the version 4.4.0 software update, QTscan breast image fidelity and diagnostic accuracy are uncompromised, and image quality remains best-in-class, with a resolution similar to magnetic resonance imaging (MRI).

Designed to meet the needs of busy breast imaging centers, the software update ensures minimal downtime and seamless integration into existing workflows. Accordingly, it enhances scalability for institutions expanding their QTI breast screening programs, ensuring consistent performance across increasing patient volumes.

“This latest software release reflects direct input from radiologists and clinical partners, underscoring our commitment to continuous innovation based on real-world use,” said QTI’s CEO, Dr. Raluca Dinu. “Faster image availability enables radiologists to review and interpret QTI scans more quickly, supporting earlier clinical decision-making. And accelerated processing reduces wait times for results, contributing to a smoother and more reassuring patient journey.”

The QTI team continues to innovate by leveraging proprietary machine learning algorithms not only to accelerate image processing via the version 4.4.0 software update, but also to actively reduce scanning time — a key focus area in ongoing development. Version 4.4.0 is optimized for systems utilizing NVIDIA’s L40 GPUs and remains fully backward-compatible with earlier QTI system hardware, ensuring broad accessibility through scalable, software-driven architecture.
