Multiresolution foveated laparoscope with high resolvability |pdf=|usr=}}{{23811873 }} gab.com Text Multiresolution foveated laparoscope with high resolvability JO: Opt Lett http://www.kidney.de/pget.php?&tw=1&pmid=23811873 #FOAvip A key limitation of the state-of-the-art laparoscopes for minimally invasive surgery is the tradeoff between the field of view and spatial resolution in a single-view camera system. As such, surgical procedures are usually performed at a zoomed-in view, which limits the surgeon's ability to see much outside the immediate focus of interest and causes a situational awareness challenge. We proposed a multiresolution foveated laparoscope (MRFL) aiming to address this limitation. The MRFL is able to simultaneously capture wide-angle overview and high-resolution images in real time; it can scan and engage the high-resolution images to any subregion of the entire surgical field in analogy to the fovea of human eye. The MRFL is able to render equivalently 10 million pixel resolution with a low data bandwidth requirement. The system has a large working distance (WD) from 80 to 180 mm. The spatial resolvability is about 45 ?m in the object space at an 80 mm WD, while the resolvability of a conventional laparoscope is about 250 ?m at a typically 50 mm surgical distance.
