Fluorescence guided surgery (FGS), also called fluorescence image-guided surgery, or in the specific case of tumor resection, fluorescence guided resection, is a medical imaging technique used to detect fluorescently labelled structures during surgery. [1]
Fluorescence imaging is a type of non-invasive imaging technique that can help visualize biological processes taking place in a living organism. Images can be produced from a variety of methods including: microscopy , imaging probes, and spectroscopy .
Even when finally improved and commercially introduced for diagnostic imaging, the limited light produced from the fluorescent screens of the earliest commercial scopes necessitated that a radiologist sit for a period in the darkened room where the imaging procedure was to be performed, to first accustom his eyes to increase their sensitivity ...
Scientists from Purdue University designed and developed OTL38 and licensed it to On Target Laboratories in 2013. [9] [10] The safety and effectiveness of pafolacianine was evaluated in a randomized, multi-center, open-label study of women diagnosed with ovarian cancer or with high clinical suspicion of ovarian cancer who were scheduled to undergo surgery.
During the surgical procedure, the IGS tracks the probe position and displays the anatomy beneath it as, for example, three orthogonal image slices on a workstation-based 3D imaging system. Existing IGS systems use different tracking techniques including mechanical, optical, ultrasonic, and electromagnetic. When fluorescence modality is adopted ...
Endomicroscopy is a technique for obtaining histology-like images from inside the human body in real-time, [1] [2] [3] a process known as ‘optical biopsy’. [4] [5] It generally refers to fluorescence confocal microscopy, although multi-photon microscopy and optical coherence tomography have also been adapted for endoscopic use.
Two-photon excitation microscopy of mouse intestine.Red: actin.Green: cell nuclei.Blue: mucus of goblet cells.Obtained at 780 nm using a Ti-sapphire laser.. Two-photon excitation microscopy (TPEF or 2PEF) is a fluorescence imaging technique that is particularly well-suited to image scattering living tissue of up to about one millimeter in thickness.
In autofluorescence, fluorescence from the eye occurs without injection of the dye. This may be seen with optic nerve head drusen , astrocytic hamartoma , or calcific scarring. Black-and-white photos give better contrast than color photos, which aren't necessary because the filter transmits only one color of light.
