New Viewer, Optimized for QT Imaging's Breast Imaging Technology, Simplifies Correlation of Breast Imaging Across Modalities and Over Time, and Supports Future Integration of AI/ML-Based Tools

Product Demonstrations Available at the SBI Breast Imaging Symposium, April 16-19 in Seattle

QT Imaging Holdings, Inc. (NASDAQ:QTI) ("QT Imaging" or the "Company"), a medical device company dedicated to transforming breast health management through innovative, radiation-free imaging technology, today announced the launch of the QTI Imaging-Olea Viewer, developed in collaboration with Olea Medical, a leader in advanced imaging software solutions.

The QT Imaging-Olea Viewer provides a unified platform for viewing multiple breast imaging modalities, enabling clinicians to efficiently correlate findings across imaging sources and monitor patients longitudinally. By reducing reliance on multiple software viewers, the system streamlines workflow, enhances clinical efficiency, and supports more informed patient management over time.

"Integrating quantitative, radiation-free QTscan data with mammography, digital breast tomosynthesis, MRI, and ultrasound in a single intuitive platform improves interpretive efficiency, strengthens diagnostic confidence, and supports a more comprehensive multimodality approach to breast evaluation," said Dr. Bilal Malik, Chief Medical Officer of QT Imaging.

QT Imaging's Breast Acoustic CT™ system leverages advanced ultrasound tomography to deliver true 3D volumetric breast imaging without ionizing radiation or painful compression. Designed to provide quantitative, reproducible imaging data, the technology offers particular clinical value in women with dense breast tissue. Powered by Olea Medical's industry leading visualization framework, the QT Imaging-Olea Viewer enables comprehensive analysis of QT Imaging datasets through advanced 3D rendering, quantitative assessment, and integrated AI/ML capabilities, including future automated lesion segmentation and computer-aided detection applications.

"Our collaboration with QT Imaging shows how advanced software and imaging innovation can seamlessly come together to benefit clinicians and patients alike," said Faycal Djeridane, Founder and Chief Executive Officer of Olea Medical. "By integrating QT Imaging's quantitative biomarkers into our advanced imaging platform, we're enabling a data-rich, cohesive viewing experience that enhances diagnostic efficiency."

The QT Imaging-Olea Viewer will be available for demonstration at the Olea Medical exhibition booth #433 at the SBI Breast Imaging Symposium, being held April 16-19 at the Seattle Convention Center. The QT-Viewer was developed under a QT Imaging and Olea Medical collaboration that was announced in January 2026.
