The VIO System is intended to acquire, store, retrieve, display and transfer in vivo images of tissue - including blood vessels, collagen, pigment, stratum corneum, hair shafts or follicles, solar elastosis, atypia, and epidermal disarray - in and through epidermis for review by physicians to assist in forming a clinical judgment. Physicians who interpret VIO System images must have dermatology medical qualifications with skin histology assessment training.

The VIO System (REF V-1000) is a light-based in vivo microscope intended to provide images of skin tissue for review by physicians to assist in forming a clinical judgment. The device does not provide image analysis or diagnostic information. The VIO System uses a handheld reflectance confocal and multiphoton microscope that contacts the skin and optically scans at a depth where most skin conditions originate, without disrupting the tissue. The VIO System delivers low power laser light of a single wavelength (780 nm infrared, Class 1M) into the skin in brief pulses. The resulting signals are acquired while imaging the skin and each signal is assigned to one of four (4) channels: RCM (Reflectance Confocal Microscopy), SHG (Second Harmonic Generation), 2PS (2-Photon Autofluorescence Short), and 2PL (2-Photon Autofluorescence Long). For each image capture, the VIO System combines the four (4) channels to display a single, multi-color image on the VIO System, referred to as "Tetrachrome™." Three (3) view modes are accessible to the user on the VIO System: Standard View, Superficial Zoom, and Deep Zoom. Acquired images are not stored on nor analyzed by the VIO System. The images are saved on a USB flash drive, which is used to transfer images to a commercially available DICOM viewer for interpretation by a physician.
