Digital radiography is a form of X ray imaging , where digital X ray sensors are used instead of traditional photographic film. Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer and enhance images. Also less radiation can be used to produce an image of similar contrast to conventional radiography. Instead of X ray film, digital radiography uses a digital image capture device. The gives advantages of immediate image preview and availability elimination of costly film processing steps a wider dynamic range, which makes it more forgiving for over and under exposure as well as the ability to apply special image processing techniques that enhance overall display of the image. Detectors There are two major variants of digital image capture devices flat panel detectors FPDs and high density line scan solid state detectors. FPDs are further classified in two main categories 1. Indirect FPDs . Amorphous silicon a Si is the most common material of commercial FPDs.

unsourced date December 2011 Merge Neutron imaging date August 2011 Neutron radiography is the process by which film is exposed by first passing neutrons through an object to produce a visible image of the materials that make up the object. It is primarily used in scientific investigations. History The neutron was discovered by James Chadwick in 1932. The first demonstration of neutron radiography was made by Hartmut Kallmann and E. Kuhn in the late 1930s they discovered that upon bombardment with neutrons, some materials emitted radiation that could expose a photographic film. The discovery remained a curiosity until 1946 when low quality radiographs were made by Peters. The first neutron radiographs of reasonable quality were made by J. Thewlis UK in 1955. Around 1960, Harold Berger US and John Barton UK began evaluating neutrons for investigating irradiated reactor fuel. Subsequently, a number of research facilities were developed. The first commercial facilities came on line in the late 1960s, mostly in the US and France , and eventually in many other countries including Canada , Japan , South Africa , Germany , and Switzerland . Neutron imaging Neutron imaging is the process of making an image with neutrons. The resulting image is based on the neutron attenuation properties of the imaged object, and these attenuation properties distinguish neutron and X ray images. Attenuation of X ray s is proportional to density denser materials stop more X rays whereas neutron absorption is not. Some light materials such as boron strongly absorb neutrons while many commonly used metals allow most neutrons to pass through them.

This is a seminal publication of the Faculty of General Dental Practice Faculty of General Dental Practice UK of the Royal College of Surgeons of England . The publication marked the standardisation of dental radiography and now provides the dental profession with a set of evidence based medicine evidence based criteria in order to minimse radiation exposure to dental patients and staff. Key recommendations were in the area of bitewing radiography where intervals between bitewing Screening medicine screening radiographs checking for dental caries between teeth were recommended based on patient risk of disease. The patient is considered to be either High, medium or low risk of dental decay. The interval between bitewings is recommended to be either 6, 12 or 18 months plus accordingly. The effect of this has been to ensure that via a process of clinical governance and clinical audit , the number of radiation exposures to patients is minimised, while allowing clinical decisions to be made based on good radiographs, improving patient outcomes. The second edition of Selection Criteria for Dental Radiography has been fully revised and updated. Several sections have been updated in light of new evidence and research findings while others, such as the use of digital radiography, have been expanded to reflect an increasing use in general dental practice. These selection criteria also conform to the Ionising Radiation Medical Exposure Regulations 2000, and help practitioners form a sound basis for clinical decisions.

Orphan date July 2009 The computed tomography dose index CTDI is a commonly used radiation exposure index in Computed tomography X ray computed tomography and is reported by the CT manufacturers to scan personnel for each exam. Definitions It is defined by the US Department of Health and Human Services HHS as the average dose imparted by a single axial acquisition to a standard 100 mm pencil chamber dosimeter inside a PMMA phantom over the width of 14 CT slices math CTDI frac 1 nT int 7T 7T D z dz math where math n math is the number of slices acquired, math T math is the slice thickness and math D z math is the radiation dose measured at position math z math along the scanner s main axis. This equation is often used in a modified form math CTDI 100 frac 1 nT int 50 mm 50 mm D a z dz math . The dose absorbed in air math D a z math can be conveniently assessed with a 100 mm standard pencil dose chamber. Typically, the dose distribution within the body cross section imparted by a CT scan is much more homogeneous than that imparted by radiography, but in still somewhat larger near the skin than in the body center. Therefore, a third measure, the weighted CTDI was introduced math CTDI w frac 1 3 CTDI 100 central frac 2 3 CTDI 100 peripheral . math Similar measures with yet wider chambers are useful for CT systems with large numbers of detector rows. ref refGeleijns2009 Geleijns 2009 ref Notes reflist 2 References cite id refRothenberg2000 Rothenberg, LN and Pentlow, KS 2000 .

orphan date December 2007 Computed Corpuscle Sectioning is a general method for determining the volume, profile area, and perimeter of a slab section of any computer modeled three dimensional object in any orientation and at any position. It was originally developed as a model of cell nuclei in a tissue section in conjunction with the Reference Curve Method for correcting ploidy measurements by image analysis in a tissue section, but it is useful for evaluating any algorithm that corrects ploidy measurements for the effect of sectioning. Computed Corpuscle Sectioning has obvious pertinence to stereology , but has not been exploited in that field.

No footnotes article date April 2009 Computed Tomography Laser Mammography CTLM is the trademark of Imaging Diagnostic Systems, Inc. IDSI, USA for its Optical tomography optical tomographic technique for female breast imaging. This medical imaging technique uses laser energy in the near infrared region of the spectra, to detect angiogenesis in the breast tissue. It is optical molecular imaging for hemoglobin both oxygenated and deoxygenated. The technology uses laser in the same way computed tomography uses X Rays, these beams travel through tissue and suffer attenuation. A laser detector measures the intensity drop and the data is collected as the laser detector moves across the breast creating a tomography image. CTLM images show hemoglobin distribution in a tissue and can detect areas of Angiogenesis surrounding malignant tumors, that stimulate this angiogenesis to obtain nutrients for growth.
