Report

Secondary spectrum after shieldings in x-ray rooms

Background: Calculating the characteristics of radiation emerging from radiation shielding to determine the level of safety in protected areas has been a widely studied topic in Radiation Protection due to its importance for the protection of the pub

Report

A model for studying the detectability of X-ray images using the representation of images in the primary visual cortex

Autor: González-López, Antonio

It is well known that the visual information represented in the simple cells of the primary visual cortex V1 is spatially localized, orientation-sensitive and bandpass-filtered. In addition, the visual information represented is subsampled. On the ot

Report

Detectability assessment of an x-ray imaging system using the nodes in a wavelet packet decomposition of a star-bar object

Autor: González-López, Antonio

Purpose: Using linear transformation of the data allows studying detectability of an imaging system on a large number of signals. An appropriate transformation will produce a set of signals with different contrast and different frequency contents. In

Report

High frequency residues: a new set of signals for detectability studies of an X-ray imaging system

Autor: González-López, Antonio

A new set of signals for studying detectability of an x-ray imaging system is presented. The results obtained with these signals are intended to complement the NEQ results. The signals are generated from line spread profiles by progressively removing
