Single-Use Duodenoscopes and Duodenoscopes with Disposable End Caps
REPORT ON EMERGING TECHNOLOGY Single-use duodenoscopes and duodenoscopes with disposable end caps Prepared by: ASGE TECHNOLOGY COMMITTEE Arvind J. Trindade, MD,1,* Andrew Copland, MD,2,* Amit Bhatt, MD,3 Juan Carlos Bucobo, MD, FASGE,4 Vinay Chandrasekhara, MD, FASGE,5 Kumar Krishnan, MD,6 Mansour A. Parsi, MD, MPH, FASGE,7 Nikhil Kumta, MD, MS,8 Ryan Law, DO,9 Rahul Pannala, MD, MPH, FASGE,10 Erik F. Rahimi, MD,11 Monica Saumoy, MD, MS,12 Guru Trikudanathan, MBBS,13 Julie Yang, MD, FASGE,14 David R. Lichtenstein, MD, FASGE, (Chair, Technology Committee)15 This document was reviewed and approved by the Governing Board of the American Society for Gastrointestinal Endoscopy. Background and Aims: Multidrug-resistant infectious outbreaks associated with duodenoscopes have been documented internationally. Single-use duodenoscopes, disposable distal ends, or distal end cap sealants could eliminate or reduce exogenous patient-to-patient infection associated with ERCP. Methods: This document reviews technologies that have been developed to help reduce or eliminate exogenous infections because of duodenoscopes. Results: Four duodenoscopes with disposable end caps, 1 end sheath, and 2 disposable duodenoscopes are re- viewed in this document. The evidence regarding their efficacy in procedural success rates, reduction of duode- noscope bacterial contamination, clinical outcomes associated with these devices, safety, and the financial considerations are discussed. Conclusions: Several technologies discussed in this document are anticipated to eliminate or reduce exogenous infections during endoscopy requiring a duodenoscope. Although disposable duodenoscopes can eliminate exog- enous ERCP-related risk of infection, data regarding effectiveness are needed outside of expert centers. Addition- ally, with more widespread adoption of these new technologies, more data regarding functionality, medical economics, and environmental impact will accrue. -

“Digital Single Lens Reflex”
PHOTOGRAPHY GENERIC ELECTIVE SEM-II DSLR stands for “Digital Single Lens Reflex”. In simple language, a DSLR is a digital camera that uses a mirror mechanism to either reflect light from a camera lens to an optical viewfinder (which is an eyepiece on the back of the camera that one looks through to see what they are taking a picture of) or let light fully pass onto the image sensor (which captures the image) by moving the mirror out of the way. Although single lens reflex cameras have been available in various shapes and forms since the 19th century with film as the recording medium, the first commercial digital SLR with an image sensor appeared in 1991. Compared to point-and-shoot and phone cameras, DSLR cameras typically use interchangeable lenses. Take a look at the following image of an SLR cross section (image courtesy of Wikipedia): When you look through a DSLR viewfinder / eyepiece on the back of the camera, whatever you see is passed through the lens attached to the camera, which means that you could be looking at exactly what you are going to capture. Light from the scene you are attempting to capture passes through the lens into a reflex mirror (#2) that sits at a 45 degree angle inside the camera chamber, which then forwards the light vertically to an optical element called a “pentaprism” (#7). The pentaprism then converts the vertical light to horizontal by redirecting the light through two separate mirrors, right into the viewfinder (#8). When you take a picture, the reflex mirror (#2) swings upwards, blocking the vertical pathway and letting the light directly through. -

Shape recognition and pattern recog- nition are one of the most important tasks in the image processing. Crime scene photographs should always be in focus and there should be always be a ruler be present, this will allow the investigators the ability to resize the image to accurately reconstruct the scene. There- fore, the camera must be on a grounded platform such as tripod. Due to the rotation of the camera around the camera center there exist the distortion in the image which must be minimized. -
Photographic Equipment Guidelines the Farm Lodge Lake Clark National Park, Alaska
Photographic Equipment Guidelines The Farm Lodge Lake Clark National Park, Alaska by Jim Barr Professional Nature, Adventure Travel, and Outdoor Sports Photographer President, American Society of Media Photographers, Alaska Chapter Photography Guide, The Farm Lodge, Lake Clark National Park Introduction. Here are some general and specific equipment suggestions for photo tour participants. These start and build from “ground zero”, so just blend this information with the equipment that you already have. Equipment is important, but...the old cliché “cameras don’t take pictures, people do” really is true. So don’t put too much emphasis on the equipment. We’ll help you get the most out of what you have. On the other hand, a bear’s face would need to be within two or three feet of the lens for a frame- filling National Geographic quality close-up with a small point-and-shoot or cell phone camera. Not healthy for the photographer (or the bear), and not too likely to happen. The right tools do help. Keep size, weight, and portability in mind. You’ll be traveling to Port Alsworth on a small plane, and deeper into the bush each day on an even smaller one. Space is limited. We’ll also be doing some walking. Bears will require a mile or so of light hiking each way. On landscape days we may hike further and sometimes over rougher terrain, but you can leave heavy wildlife gear at the lodge or in the airplane. We do have options that limit the walking necessary, but there will always be some. -
HASSELBLAD INTRODUCES the H6D-400C MS, a 400 MEGA PIXEL
Press information – for immediate release Gothenburg, Sweden 16 Jan 2018 HASSELBLAD INTRODUCES THE H6D-400c MS, A 400 MEGA PIXEL MULTI-SHOT CAMERA Building on a vast experience of developing exceptional, high-quality single and multi-shot cameras, Hasselblad once again has raised the bar for image quality captured with medium format system. Multi-Shot capture has become an industry standard in the field of art reproduction and cultural heritage for the documentation of paintings, sculptures, and artwork. As the only professional medium format system to feature multi-shot technology, Hasselblad continues to be the leading choice for institutions, organizations, and museums worldwide to record historic treasures in the highest image quality possible. With over 10 years of digital imaging expertise, the latest Multi-Shot digital camera combines the H6D’s unrivalled ease of use with a completely new frontier of image quality and detail. This new camera encompasses all of the technological functions of Hasselblad’s H6D single shot camera, and adds to that the resolution and colour fidelity advancements that only Multi-Shot photography can bring to image capture. With an effective resolution of 400MP via 6 shot image capture, or 100MP resolution in either 4 shot Multi-Shot capture or single shot mode, the Multi-Shot capture requires the sensor and its mount to be moved at a high-precision of 1 or ½ a pixel at a time via a piezo unit. To capture Multi-Shot images the camera must be tethered to a PC or MAC. In 400MP Multi-Shot mode, 6 images are captured, the first 4 involve moving the sensor by one pixel at a time to achieve real colour data (GRGB- see 4 shot diagrams below), this cycle then returns the sensor to its starting point. -
