The Critical Need for Precision
Cancer surgery represents one of medicine's most significant challenges: surgeons must remove every cancerous cell while preserving as much healthy tissue as possible, often making difficult decisions that determine patient survival and quality of life. Traditional surgery relies heavily on the surgeon's experience and tactile feedback to distinguish between healthy and cancerous tissue, leading to incomplete tumor removal in some cases or excessive healthy tissue removal in others. Without real-time molecular-level guidance, surgeons face an inherent trade-off between thoroughness and preservation, resulting in variable outcomes that depend on individual expertise rather than standardized, data-driven precision. Our image-guided surgery research addresses this fundamental limitation by providing surgeons with intelligent imaging systems that reveal cancer at the molecular level during operations, enabling complete tumor removal while minimizing damage to healthy tissue and improving consistency across all surgical procedures.

How Image-Guided Surgery Works: Image-guided surgery operates through three integrated components during operations. The camera system uses near-infrared sensors that detect fluorescent signals outside the visible spectrum, mounted on surgical microscopes or handheld devices that display video feeds to operating room monitors. The fluorescent dye is administered to patients before surgery—either as contrast agents that accumulate in tumors through vascular permeability differences, or as targeted probes that bind to specific cancer cell receptors like EGFR—producing fluorescent signals that differentiate cancerous from normal tissue. Data processing algorithms enhance these fluorescent signals in real-time, improving signal-to-noise ratios, defining tissue boundaries, and overlaying fluorescent information onto standard surgical video, providing surgeons with additional visual information about tissue characteristics during tumor removal procedures.
