Pixel-driven computation of parallel and fan-beam projections of a digital image based on pixel-representation using a new formula

Comput. Methods Programs Biomed., 2022
BACKGROUND The computation of the projections of a digital image - modelled as a superposition of square pixels - is essential in several algorithms in computed tomography, and also in many machine vision applications.

Investigation of Buildup Region and Surface Dose: Comparison of Parallel Plane Ion Chamber, Treatment Planning System, and MC Simulation

Nuclear Technology, 2021
In these days, Monte Carlo (MC) simulation is a method that can calculate the radiation dose that occurs in an environment in the most accurate way. The correct measurement of the dose occurring on the patient’s surface is of great importance to estimate

Interference of two diverging beams reflected from a plane parallel plate: stationary fringes with characteristic stable period.

Applied Optics, 2020
We investigated interference fringes due to superposition of diverging light waves reflected from the two sides of a plane parallel plate. A non-localized fringe pattern of high contrast was obtained as a function of incident angle when we used a ...

A Reconfigurable Variable-Stiffness Parallel Beam for Compliant Robotic Mechanisms Towards Safe Human Interaction

Volume 8A: 45th Mechanisms and Robotics Conference (MR), 2021
To co-work with humans, robotic mechanisms need to have variable stiffness with high rigidity for performance and low compliance for safe interactions.

Design, fabrication and characterization of an electrical-explosively actuated MEMS flyer-accelerator inserted with parallel bridge foils

, 2020
Parallel bridge foils (PBF) with four strip foils, which is derived from traditional single bridge foil (SBF), was designed to study the effect of convergence and collision of plasmas and shock waves on driving flyer.

Research on array laser tilt correction technology based on composite sensing

Other Conferences, 2023
In order to achieve accurate superposition of array lasers in the far field and ensure the quality of the array laser synthetic beam, it is required that the array laser sub-beams point in the same direction, i.e., there is no tilt aberration between the
