Identifying GFP-transgenic animals by flashlight.
In recent years, GFP has proven to be a valuable tool in many biological systems. Wild-type GFP has a major absorption in the UV region at 398 nm and a minor absorption in the blue region at 475 nm (3). Recently, several groups have independently carried out amino acid modifications of the GFP protein and have optimized these optical characteristics (6). For a comprehensive review on the photop...
متن کاملProgress Towards a Clinically Useful Sonic Flashlight
We have demonstrated a new method of displaying ultrasound images in situ within the patient, using a half-silvered mirror attached to the ultrasound transducer. The mirror reflects the ultrasound image from a flat-panel monitor (also attached to the transducer) so that the virtual image occupies its actual location within the patient. The observer sees the ultrasound image merged with a direct...
متن کاملLaser Needle Guide for the Sonic Flashlight
We have extended the real-time tomographic reflection display of the Sonic Flashlight to a laser guidance system that aims to improve safety and accuracy of needle insertion, especially for deep procedures. This guidance system is fundamentally different from others currently available. Two low-intensity lasers are mounted on opposite sides of a needle aimed parallel to the needle. The needle i...
متن کاملFlashlight as a Process Tracing Method
Flashlight is an open source process-tracing tool that records mouse movements in real time during an information search task (Schulte-Mecklenbeck, Murphy & Hutzler, 2011). Using this tool, acquisition behavior and visual attention can be recorded in an unobtrusive way with a wide variety of different stimuli. Because of the structure of the stimuli in Flashlight, information acquisition behavi...
متن کاملPeripherally inserted central catheter placement using the Sonic Flashlight.
The Sonic Flashlight is an ultrasound (US) device that projects real-time US images into patients with use of a semireflective/transparent mirror. The present study evaluated the feasibility of use of the Sonic Flashlight for clinical peripherally inserted central catheter placements, originally with the mirror located inside a sterile cover (n = 15), then with the mirror outside (n = 11). Succ...
