Fluorescence Imaging for Rare Cell Detection

Detecting circulating tumor cells (CTCs) remains a significant analytical challenge due to their extreme rarity. Only about 1–10 CTCs are typically present per mL of whole blood, and current technologies often must identify a single CTC among nearly 10 million nucleated blood cells. This rarity drives the need for highly sensitive platforms capable of resolving these exceptionally scarce events.

The Detection Challenge

The AXON Dx imaging systems were originally developed to address the technical challenges of circulating tumor cell (CTC) detection and have evolved into adaptable rare-cell research platforms.

Key Capabilities

AXON Dx imaging systems integrate precision optics, automated scanning, and AI-driven analytics into a unified platform architecture.

Multi-Channel Fluorescence Imaging

High-resolution multi-spectral fluorescence imaging enables simultaneous visualization of multiple biomarkers across the full slide area, providing rich phenotypic data for each detected cell.

Automated Whole-Slide Scanning

Fully automated slide scanning eliminates manual search bias and ensures complete sample coverage, capturing every rare event present in the specimen.

High-Resolution Digital Image Capture

High-fidelity digital capture preserves morphological detail at the cellular and subcellular level, supporting downstream characterization and archiving.

AI-Assisted Cellular Identification

Artificial intelligence driven algorithms identify and classify rare cells — distinguishing CTCs, CSCs, TILs, and circulating endothelial cells from background populations with high specificity.

Structured Data Archiving

All scan data, cell coordinates, and image captures are stored in a structured format for longitudinal tracking, retrospective analysis, and collaborative research workflows.
