Mammography vendor Fischer Imaging has hired imaging industry veteran Gerald Knudson as CEO. Knudson replaces Louis Rivelli, who will be advising Fischer on operational matters during a transition period, according to the Denver-based vendor.
Knudson has been serving on Fischer's board since 2000. As the firm works to promote its SenoScan full-field digital mammography system (FFDM) and market growth in screening mammography procedures, it will focus on expanding its direct sales force in both the U.S. and Europe, Knudson 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.auntminnie.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)
