What is the Digital gamma radiography equipment?

Gamma radiography equipment is imaging technology that produces high-quality optical anatomic images using. General gamma radiography equipment is currently the biggest part of the hospital imaging units, and it contains the abdomen, the chest and the head of the checks.

Digital gamma radiography equipment usage has increased rapidly in recent years. Calculated on the basis of gamma radiography equipment provided cost-effective transition mode (since 1895) of gamma radiography equipment by traditional polyeteenikalvosta directly to digital (DDR), in order to achieve by conventional x-ray equipment.Direct digital gamma radiography equipment (camera) mode with a tape-less imaging system, and is ideal for applications where suurikapasiteettisia are of paramount importance. directly to the digital gamma radiography equipment system should allow for the use of gamma radiography equipment all General diagnostic applications.

Digital gamma radiography equipment important parts of the system are the following:
1. X-Ray Generator
2. X-Ray Assembly
3. Table trolley or other device supports the patient's
4. support for the x-ray tube Assembly
5. tell-tale, which converts optical image
6. Acquisition workstation can process and display the picture

There is a variety of techniques, including direct digital gamma radiography equipment is based on:
1) Indirect conversion indicator: optical is converted into light and light is converted into electrical scintillations signals.
2) directly to the Conversion of identification: optical signals directly convert electrical.
3) Linear Scanning Detectors: the fan with the jib adjusted to an x-ray checks to see if any of the examined area synchronously with the departure of the indicators.

The indicators on the structure of the expenses to be paid directly and indirectly to convert the x-ray detectors are often called flat panel indicators (FPD).Also, portable digital cassettes available, sold as part of the system, or may not be retrofitted to existing CR or film/screen space. Portable detectors can be used in conjunction with the x-ray with a mobile unit.Review of the status of the work may be combined with such detectors through recordings of the radio link.

The biggest part of the digital indicators have some level of control of the environment. This can be in terms of operating temperature range, temperature and/or relative humidity rate.

The detector of the original image is likely to be suitable to operate; Image processing is applied to the Flat field correction is used. [1] [2], as a general rule, the raw image to the account of the variations of the detector response throughout the entire region, in addition to the amount of the individual pixels. [1] [2] may be faulty.

The majority of the units of gamma radiography equipment directly to digital will receive automatic exposure control (AEC) gives the detector of the selected dose. This uses the conventional AEC-detector or a true picture of the detector to determine the correct dose levels are used. [1] [2] it is important that the AEC acts as a reliable and consistent manner and that it is correctly configured to the exposure of the detector.

Optimization is the process for the purpose of identifying the radiation dose level should provide adequate clinical data in particular for review. Optimization depends on a number of clinical and technical factors.

Modern digital gamma radiography equipment systems is funding "the tell-tale for the dose indicator. Detector dose indicator (DDI) gives a level of exposure to radiation received by the detector. [3] [4] this is useful for monitoring that exposure is the correct region in order to make the best possible image quality, and the company's QA.
