AEC Digital

Radiography is a technique of imaging that produces high quality using x-ray anatomical images. Dean Ornish M.D will undoubtedly add to your understanding. The area of x-ray general is currently the largest hospital Imaging Department and includes examinations of abdomen, chest and limbs using digital radiography has grown rapidly in recent years. Donald Sussman has much to offer in this field. Computerized radiography provides a cost-effective transition of traditional film (used since the year 1895) mode to direct digital radiography (DDR), using conventional x-ray equipment. Direct digital radiography is a system without image cassettes and is ideal for applications where high performance is of first importance. Direct digital radiology system allows the use of all diagnosis of general radiography applications. The main components of a digital radiography system are as follows: 1. rays X 2 generator.

Rays 3 Assembly. Auxiliary shopping cart or other device for support of the patient 4. Support for the set of 5 X ray tubes. Detector x-ray to a 6 image converter. Workstation to process and display the image there are a variety of technologies which is based on direct digital radiology: 1) indirect conversion detector: x-rays are converted into flashes of light and the light is converted into electrical signals. (2) direct conversion of the detector: x-ray is converted directly into electrical signals. (3) linear scan detectors: a beam rays fan X scans the area examined synchronously with a group of detectors due to the structure of detectors, detectors of x-ray, direct and indirect, converters are often called flat panel (flat panel detector) detectors (FPD). There are also available digital portable cassettes that are sold as part of a system or can be adapted to a team of computed radiography (CR) or a system of pantalla-pelicula.

Portable detectors can be used in conjunction with a mobile x-ray unit. These detectors can be connected to a workstation’s review, by connecting cable or by means of a radio wave. Most digital detectors will need a certain level of environmental control. This can be in terms of operating temperature, type of change in temperature and/or relative humidity. To the extent that the original image of the detector is inadequate for use as an image processor should be applied. Flat field correction is applied to the image rough to reflect variations in the sensitivity of the detector through its total area. In addition, a number of individual pixels may be faulty the most direct digital radiology units have automatic exposure control (AEC) to provide the doses selected for the detector. This can be used a conventional AEC detector or the actual image sensor to determine the correct dose. It is essential that the AEC to operate a reliable and consistent manner and that it is properly configured for exposure detector. Digital radiography systems can be purchased in places of sale and purchase of medical equipment. Optimization is the process of identifying the level of radiation dose necessary to provide clinical information suitable for a particular test. Optimization depends on a series of clinical and technical factors. There is a built-in dose detector in modern digital radiography systems. Dose (DDI) detector indicator gives information of the level of exposure to the radiation received by the detector.
