Real-time spectral imaging in three spatial dimensions.
We report what is to our knowledge the first volume-holographic optical imaging instrument with the capability to return three-dimensional spatial as well as spectral information about semitranslucent microscopic objects in a single measurement. The four-dimensional volume-holographic microscope is characterized theoretically and experimentally by use of fluorescent microspheres as objects.
متن کاملSimulation of a Neutron Detector for Real Time Imaging Applications
Monte Carlo Method is used to simulate a double layer gadolinium-amorphous silicon thermal neutron detector. The detector fabricated in pixel array configuration has various applications including neutron imaging. According to the simulation results, a detector consisting of a gadolinium (Gd) film with thickness of 2-4 ~m, sandwiched properly with two layers of sufficiently thick (-30 ?µm) hydr...
متن کاملReal-time spatial compound imaging in breast ultrasound.
To determine the role of real-time spatial compound imaging in breast ultrasound (US), 38 patients with a total of 50 benign changes (fibroadenomas, cysts, lactiferous duct dilatation) underwent both conventional B-mode US and real-time spatial compound imaging under standardized examination settings. Subsequently, images were reviewed independently by three readers experienced in breast US and...
متن کاملSpatial Visualization in Two vs. Three Dimensions
Several studies (e.g. Kerr, 1987; 1993; Diwadkar, Carpenter & Just, 2000) have asked participants to report the final location of a point after imaginary moves through 2D and 3D arrays. The results suggest that visualizing 3D space is inherently more difficult than 2D visualization, and may even use different brain mechanisms. However, 2D and 3D trials were presented in separate blocks, so part...
متن کاملSpatial learning by mice in three dimensions
We tested whether mice can represent locations distributed throughout three-dimensional space, by developing a novel three-dimensional radial arm maze. The three-dimensional radial maze, or "radiolarian" maze, consists of a central spherical core from which arms project in all directions. Mice learn to retrieve food from the ends of the arms without omitting any arms or re-visiting depleted one...
