Nowadays, the demand for 3D models of historical monuments is continuously growing in the field of archaeological and architectural applications. Currently, the two main sources that can provide detailed and reliable 3D surface models are Photogrammetry through image-based modeling and Terrestrial Laser Scanner through laser scanning techniques. Among the plenty of works so far presented the us...

The structure of 2-amino-6-(4-methyl-l-piperazinyl)4-(tricyclo[3.3.1.13,7 ]dec1-yl)1,3,5-triazine was refined using data collected at three different temperatures [room temperature (293 K), 150 K and 85 K] with the use of an image-plate scanner in an attempt to study the effect of temperature on the disorder of the adamantyl group. It is demonstrated that the data collected with the rotation me...

PURPOSE Acquisition of laser range scans of an organ surface has the potential to efficiently provide measurements of geometric changes to soft tissue during a surgical procedure. A laser range scanner design is reported here which has been developed to drive intraoperative updates to conventional image-guided neurosurgery systems. METHODS The scanner is optically-tracked in the operating roo...

A new hand-held laser range scanner is introduced that can capture multi-view range images of an object and integrate the images without registering them. The scanner uses a reference double-frame that acts as the coordinate system of the object. Range images captured from different views of the object are in the coordinate system of the double-frame and, thus, automatically come together. A si...

Background: The HU linearity is an essential parameter in a quantitative imaging and the treatment planning systems of radiotherapy. Objective: This study aims to evaluate the linearity of Hounsfield unit (HU) in applying the adaptive iterative dose reduction (AIDR) on CT scanner and its comparison to the filtered back-projection (FBP).Material and Methods: In this experimental phan...

I. Introduction With rapid progress of memory chip, image processing LSI, and personal computers (PC), cost-effective PC-based image processor is sufficiently realizable. This paper describes Video Workstation, a newly-developed video ~rocessing system, that features both a high-speed image processing board which contains a microprogrammable VLSI chip, and multimedia processing. The system cons...
