ThinkSono, a U.K. company developing artificial intelligence (AI) software to diagnose deep vein thrombosis (DVT) on ultrasound, is to receive funding from Bayer as part of its Grants4Apps Accelerator program.
One of four digital health start-up companies selected for Bayer's 2017 Grants4Apps Accelerator initiative, ThinkSono leverages deep neural networks and portable ultrasound scanners to help healthcare professionals diagnose DVT at the point of care. The company has backing from a team of clinicians, engineers, and investors from Berlin and London as it develops a platform for ultrasound analysis and diagnosis of vascular diseases, according to Bayer.
All four start-ups -- ThinkSono, Aparito, Oratel Diagnostics, and Sky Labs -- receive 50,000 euros in financial support, and have already moved into the G4A Accelerator premises at Bayer's pharmaceutical division headquarters in Berlin. The companies will be mentored and supported there by Bayer senior managers and external experts until late November, Bayer said.















![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.auntminnieeurope.com/mindful/smg/workspaces/default/uploads/2026/07/2026-07-14-radiology-mammogram-ai-auto-bias.H0bYO8QlWs.jpg?auto=format%2Ccompress&fit=crop&h=112&q=70&w=112)
