Laser surgical microscopes should enable uniform illumination of the operative field, and require less luminous energy compared with existing xenon surgical microscopes.

Name: Operative neurosurgery (Hagerstown, Md.)
This article demonstrates surgical techniques of intraoperative fluorescence imaging using indocyanine green, focusing on its application in minimally invasive hepatobiliary and pancreatic surgery. In...
Digital subtraction angiography (DSA) is the gold standard for vascular imaging, but is not easily integrated into a continuous microsurgical environment. Other available modalities for intraoperative...
Laparoscopic cholecystectomy is the standard surgical treatment for patients with benign gallbladder disease. However, bile duct injury continues to be reported as a surgical complication. Intraoperat...
Acute intestinal ischaemia is a life threatening disease. CT scans may be misleading and can complicate or delay diagnosis. In this video we demonstrate that diagnostic laparoscopy with intraoperative...
The use of intraoperative fluorescence has proven to be a useful tool in multiple neurosurgical procedures with a potential utility in treating arteriovenous malformations (AVMs). The aim of this stud...
Aim of this clinical study is to establish a novel technique, the so called intraoperative fluorescence angiography, for kidney graft perfusion visualization during the transplant procedur...
Intraoperative surgical fluorescence microscopy is a useful technique for the surgical resection of glioma. However the accuracy of this method is limited by its too low sensitivity. Fluo...
This is a randomized, controlled, parallel study to determine the difference in post-operative anastomotic leak rate of colorectal anastomosis where colon and rectal tissue perfusion is ev...
The use of fluorescence for real-time evaluation of organ and tissue vascularization and lymph node anatomy is a recent technology with potential for the surgical treatment of cancer. The ...
Main Outcome: To assess the effectiveness of new intraoperative technologies in the resection of intracranial tumors. Design: Prospective observational study. Method: Prospective o...
A light microscopic technique in which only a small spot is illuminated and observed at a time. An image is constructed through point-by-point scanning of the field in this manner. Light sources may be conventional or laser, and fluorescence or transmitted observations are possible.
Microscopy of specimens stained with fluorescent dye (usually fluorescein isothiocyanate) or of naturally fluorescent materials, which emit light when exposed to ultraviolet or blue light. Immunofluorescence microscopy utilizes antibodies that are labeled with fluorescent dye.
Non-invasive method of vascular imaging and determination of internal anatomy without injection of contrast media or radiation exposure. The technique is used especially in CEREBRAL ANGIOGRAPHY as well as for studies of other vascular structures.
Fluorescence microscopy utilizing multiple low-energy photons to produce the excitation event of the fluorophore. Multiphoton microscopes have a simplified optical path in the emission side due to the lack of an emission pinhole, which is necessary with normal confocal microscopes. Ultimately this allows spatial isolation of the excitation event, enabling deeper imaging into optically thick tissue, while restricting photobleaching and phototoxicity to the area being imaged.
A type of IN SITU HYBRIDIZATION in which target sequences are stained with fluorescent dye so their location and size can be determined using fluorescence microscopy. This staining is sufficiently distinct that the hybridization signal can be seen both in metaphase spreads and in interphase nuclei.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
