The purpose of this study was to quantify the performance and assess the utility of two different types of scanners for radiochromic EBT film dosimetry: a commercial flatbed document scanner and a widely used radiographic film scanner. We evaluated the Epson Perfection V700 Photo flatbed scanner and the Vidar VXR Dosimetry Pro Advantage scanner as measurement devices for radiochromic EBT film. ...

Photon beam dosimetry using Kodak extended dose range (EDR2) radiographic film can provide accurate and high spatial resolution information especially for areas such as IMRT dosimetry where a higher dose level (100-400 cGy) is often required to be delivered for verification. For such dosimetry checks, it may sometimes be useful to place the film in a tank filled with water during irradiation. T...

BACKGROUND AND AIM: The purpose of this study was to evaluate the sensitometric characteristics of Ultraspeed, Ektaspeed Plus and Insight dental radiographic films using manual and automatic processing systems. METHODS: In this experimental invitro study, an aluminum step-wedge was used to construct characteristic curves for D-, Eand F-speed radiographic films (Kodak Eastman, Rochester, USA). A...

The selection and use of any method to be used for radiography depends on a number of considerations, these in general being: a) The size, shape, orientation and distribution of imperfection in the weld. b) The dimensions, geometry and physical properties of the weld and material. c) The radiographic sensitivity required by the Standard, Code or Specification. d) Cost of radiography. e) The loc...

including the Navy’s Fleet Readiness Centers (FRC) are faced with replacing aging chemical and film-based radiographic imaging systems used for non-destructive testing (NDT) (or nondestructive inspection (NDI)) with systems that do not rely on such an approach—so called computed radiography (CR) systems. However there are benefits, requirements, concerns, and challenges associated with implemen...

The degree of angulation of the X-ray beam relative to the radiographic film is a limiting factor in obtaining diagnostic quality flexor view radiographs. The use of an angled cassette tunnel yields an improvement in the quality of the radiographs obtained.

Introduction: Various systems for intraoral digital radiography have been available as an alternative to film–based radiography. In consideration of several advantages of digital radiography such as less patient absorbed dose, manipulation of im‌age quality and elimination of processing, it has been extensively used in different fields of denti‌stry in recent years. The purpose of this study wa...
