Digital pathology image analysis algorithms

Confidence starts with clarity

Harness the power of artificial intelligence to remove time-consuming quantification and qualification tasks from your pathology workflow, allowing you to focus on more meaningful tasks.

The uPath image analysis algorithms for pathology decision support extract meaningful information from pathology slide images so that pathologists can quickly, accurately and confidently assess immunohistochemistry and in-situ hybridization. Algorithms in the uPath image analysis algorithm suite provide image analysis of VENTANA slide scanner images stained with a Roche Tissue Diagnostics assay.

In 2011, Roche was the first company to receive 510(k) clearance from the U.S. Food and Drug Administration (FDA) on our first generation image analysis algorithms (i.e., VENTANA Companion Algorithm HER2 (4B5))1. At the time, Roche was the only company in the industry offering a comprehensive portfolio of FDA-cleared image analysis algorithms and digital read applications for the five key immunohistochemistry (IHC) breast markers.2 Since then, the technology has evolved and we have launched whole slide analysis image analysis algorithms including uPath HER2 (4B5) image analysis, Breast3, uPath HER2 Dual ISH image analysis, Breast3, uPath PD-L1 (SP263) image analysis, NSCLC3,  uPath ER (SP1) image analysis, Breast4, uPath PR (1E2) image analysis, breast4 and uPath Ki-67 (30-9) image analysis, breast.4

Roche is invested in aiding the pathologist and will continue to deliver next-generation image analysis algorithms that provide pathologists with more tools to improve efficiency and precision.


Efficient slide evaluation

“A positive resection margin of a melanoma in situ which had been initially missed using remote-controlled microscopy was identified using WSI”.

Dr. Belen Lloveras,

Chief of the Pathology Department


Enhancing precision medicine

“Precision medicine isn’t just about giving a drug to a particular patient; it’s about giving a specific diagnosis to that patient so they can get specific treatment. Roche Digital Pathology helps us to give precision diagnoses.”

Dra. Ma Dolores Lozano Escario, 

Joint Director of the Anatomic Pathology Department

As an innovator of diagnostic solutions, Roche offers your pathology laboratory a robust and reliable combination of instrumentation, medical value assays and a fully integrated digital pathology solution.

Our image analysis algorithms generate accurate, objective, and reproducible results. Trained using a robust and representative data set, they quickly and automatically classify cells and provide assay-specific scoring. By reducing the time spent performing these, and other, tasks, laboratories can free up resources to meet pressing needs and create a highly efficient workflow.
