An increasing number of diagnostic X-ray departments are opening their doors for direct referral of patients from general practitioners without the intervention of a clinical consultant before the patient is radiographed. Communication between diagnostic radiologist and practitioner is direct and hence increased responsibility falls upon both. With this in mind we are concerned with two associa...

BACKGROUND Chronic cough in children is a common problem, and sinusitis is a common etiology. The diagnosis of sinusitis is often clinical, but confirmation is thought to require a CT scan due to the difficulty of interpreting a Water's view sinus X-ray. OBJECTIVES The purposes of the study were (1) to examine the frequency of an abnormal sinus X-ray in children with a chronic cough of more t...

The objectives of this study were to document imaging physics parameters associated with mammography physics surveys, and investigate how the choice of tube potential affects average glandular dose (AGD) and x-ray exposure time. Data from 60 mammography units were obtained pertaining to representative values of mAs, exposure time, half value layer, AGD and film density when acquiring phantom im...

Abstract: Different thickness of Cu2S thin films were prepared by vacuum evaporation under a pressure of 10-6 torr at an evaporation rate of 3Å /sec. Cu2S has direct band gap energy and indirect band gap energy at 1.2eV and 1.8 eV respectively. This paper presents the analysis of structural and optical properties of the Cu2S thin film by X-ray diffractometer (XRD) and UV-Vis-NIR Spectrophotomet...

The authors attempted to obtain a quantitative index of X-ray opacity of the maxillary sinus using a digital disposition system. X-ray films of the Waters' view were used for analysis. A cooper wedge was placed on the left side of the subject's face and was simultaneously filmed. The wedge was made of copper plates increased in thickness from 0.2 to 4.0 mm in 20 steps and serving as a calibrati...

tungsten trioxide (wo3) films have been coated on indium thin oxide (ito) conductive glass substrate, using aqueous solution of peroxotungstic acid (pta) by the sol-gel dip coating method. x-ray diffractometery (xrd) analysis confirmed monoclinic and triclinic structure for the film and powdered wo3 respectively. fourier transforms infrared spectroscopy (ft-ir) exhibited the structure of peroxo...

LLE Review, Volume 83 119 Introduction X-ray imaging and x-ray spectroscopy are used in laser– plasma-generated physics research to diagnose conditions in the laser targets. Examples of techniques used to image x-ray emission are pinhole cameras, Kirkpatrick–Baez (KB) microscopes, curved crystal optics, and Wölter microscopes.1–3 All spectroscopic diagnostics rely also on spatial resolution to ...

FIGURE 1 : Chest x-ray film before treatment, showing cardiac enlargement and pulmonary congestion. There is pleural fluid on both sides, and a wedge-shaped shadow in the right mid-lung extending from the mediastinal shadow to the lateral thorax wall. FIGURE 2 : Chest x-ray film nine days later, after treatment with digitalis and diuretics. The “tumor” has disappeared, but there still remains a...
