QT Imaging Holdings Inc. has launched its latest QTviewer, version 2.8. QTviewer stores and displays the QTscan images generated by the company’s U.S. Food and Drug Administration-cleared QTI Breast Acoustic CT scanner, 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.

Key features of QTviewer 2.8 include:

1. Effortless, Stateless DICOM (Digital Imaging and Communications in Medicine) Viewing: QTviewer 2.8 enables instant access to QTscan studies without a preconfigured database—ideal for remote reads, portable drives, or low-resource environments. This also supports direct PACS (Picture Archiving and Communication System) integration where available.
2. Real-Time Lesion Doubling Time Analysis: Integrated tool allows clinicians to assess lesion growth within the standard reading workflow—enhancing disease progression monitoring or treatment response. Unlike conventional methods, QTI’s technology enables fully quantitative, volumetric analysis without the need for contrast agents or ionizing radiation.
3. New RGB Visualization Modes: Enables interpretation of both anatomical structures and quantitative data, supporting diagnostic and research use cases alike. The RGB mode incorporates speed of sound mapping, providing additional visual representation of tissue composition and imaging findings, an essential capability for advancing our research into lesion characterization and AI-driven classification.
4. Advanced Multi-Series Comparison: Radiologists can now view multiple series from the same study in parallel windows, improving anatomical and temporal comparisons.
5. Optimized Viewport Layouts for Radiology Workstations: Vertical orientation and multi-monitor support improve ergonomics and diagnostic clarity for stackable and long-axis views.
6. Secure License Management for Enterprise Use: PC-based license key verification ensures secure, compliant deployment across hospital and academic systems.
7. Improved Stability and Usability: Backend upgrades streamline loading, enhance compatibility, and support quick launches from file associations or command line.
8. Reinforced Diagnostic Workflow: QTviewer 2.8 provides automatic recognition of image types, such as speed-of-sound, attenuation, and reflection, ensuring seamless workflow and consistent interpretation.

“This is an exciting time for our team as we enter into a period of anticipated rapid growth, driven by continuous innovation like our recent release of image reconstruction software, version 4.4.0, which delivers a substantial reduction in the QTscan image processing time, improving user throughput and overall efficiency, and this enhanced generation of QTviewer,” QTI Chief Science Officer Dr. Bilal Malik said. “By providing radiologists and clinical partners with a growing portfolio of enabling, intuitive support tools, QTI aims to expand access to medical imaging while ensuring superior patient experience and improving health outcomes.”

Transforming QTI into a precision imaging AI company is a key pillar of the company’s growth strategy. The QTI team continues to innovate by not only developing proprietary AI/ML tools designed to accelerate image processing and reduce scanning time, but also conducting AI/ML projects which will be viewed/integrated in the QTviewer in the future.
