Design outcomes

Primary

MeasureTime frame
The newly developed photoacoustic endoscopic probe can classify different tissue pathological conditions in colorectal mucosa by utilizing the distinct optical absorption properties of biomarkers such as collagen, NADH, elastin, and FAD. These biomarkers allow the probe to distinguish between normal, adenomatous, and carcinomatous tissues. Integrating machine learning into the system further enhances diagnostic accuracy by recognizing complex patterns in the spectral data, offering a non-invasive, real-time tool for early detection and improved treatment of colorectal cancer.Timepoint: Three years

Secondary

MeasureTime frame
This study has the potential for translation into clinical practice.Timepoint: 5 years
