QT Imaging has released version 4.5.0 of its image reconstruction software for its QTI Breast Acoustic CT system.
The update improves spatial resolution in reflection imaging through optimized, spatially varying deconvolution during image reconstruction, the company said. It also introduces enhanced reflection images generated by fusing speed-of-sound and reflection data to provide improved tissue characterization, according to QT Imaging.
The QTI Breast Acoustic CT system is a noninvasive technology that creates 3D breast images without compression, contrast agents, or ionizing radiation, the company noted. Additional software changes include improved image reconstruction for small breasts and more accurate assessment of fibroglandular tissue composition in breasts with implants.
![A normal mammogram confirmed by three-year radiologic follow-up illustrates reader-marked regions of interest (ROIs) during (A) unaided (round 1) and (B) artificial intelligence (AI)–assisted (round 2) reading. Each colored dot represents an ROI for recall by a human reader. Readers could mark more than one ROI per case, represented by multiple dots of the same color. During AI-assisted reading, the AI system displayed three visible prompts: two with suspicion of malignancy scores of 35% (left mediolateral oblique [L MLO] and craniocaudal [L CC]) and one with a suspicion of malignancy score of 10% (right craniocaudal [R CC]), shown as polygonal overlays. Without AI, six of 10 readers (60%) marked a false-positive ROI. With AI assistance, this fell to two of 10 (20%). R MLO = right mediolateral oblique.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/07/2026-07-14-radiology-mammogram-ai-auto-bias.H0bYO8QlWs.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
