 Cellvizio Lung Mauna Technology Confocal microscopy is the standard tool for ultrahigh resolution imaging in biomedical research. Mauna Technology has developed a 1.4mm diameter Alveoflex Confocal MiniprobeTM which can be deployed down the working channel of a standard bronchoscope. Elastin is the main in vivo fluorophore, and images are acquired by gentle contact, providing microstructural detail of the alveolus on multiple tissue layers. Because the system takes advantage of the natural fluorescence of the lung tissues, no patient preparation is required.
