Currently available screen and retinal head mounted displays have insufficient field of view to fully exploit many virtual and augmented reality applications. Screen based displays suffer from weight and size restrictions as the image sources, electronics, and viewing optics need to be head mounted. Retinal displays need only the scanning and optical delivery components to be head mounted, but ...

Introduction: Mini Computed Tomography (mini-CT) was suggested in biomedical research to investigate tissues and small animals. We present designed and built a mini x-ray computed tomography (mini-CT) for small animals as well as industrial component imaging. Materials and Methods: The system used in this study includes a X-ray tube 20kV to 160kV and a flat pa...

Abstract The Polar Radiant Energy in the Far InfraRed Experiment (PREFIRE) will fill a gap our understanding of polar processes and climate by offering widespread, spectrally-resolved measurements through (FIR) with two identical CubeSat spacecraft. While regions are typically difficult for skillful cloud identification due to cold surface temperatures, reflection bright surfaces, frequent temp...

introduction: conventional methods for diagnosis of external root resorption (err) are based on clinical findings and x-ray observations which are not appropriate for early diagnosis. the present study assessed the effect of different sizes and field of views (fovs) in the diagnosis of simulated external root resorption by cone-beam computed tomography (cbct). methods and materials: in this dia...

conclusion no significant differences were found among observers or voxel sizes, with high az results reported for all groups. results no significant differences were found among observers or voxel sizes, with high average z (az) results being reported for all groups. both intra- and inter-observer agreement values were relatively better for 3d accuitomo 170 images than the images from newtom 3...

Recent improvements in intravascular magnetic resonance imaging techniques mandate an accurate method of monitoring the introduction of MR catheter probes into the vessel of interest. For this purpose, a novel imaging protocol and a display method have been designed. First, a roadmap 3D image data set with standard pulse sequences is obtained using an external imaging coil. Subsequently, using ...

Objective(s): The present study was conducted to examine whether the standardized uptake value (SUV) may be affected by the spatial position of a lesion in the radial direction on positron emission tomography (PET) images, obtained via two methods based on time-of-flight (TOF) reconstruction and point spread function (PSF). Methods: A cylinder phantom with the sphere (30mm diameter), located in...

True 3D CT dataset for treatment planning of an oversized patient is difficult to acquire due to the bore size and field of view (FOV) reconstruction. This project aims to provide a simple approach to reconstruct true CT data for oversize patients using CT scanner with limited FOV by acquiring double partial CT (left and right side) images. An efficient line profile-based method has been develo...
