However, regardless of these many advantages, we must be aware that digital imaging also has its downsides. • The silver lining can function a quality control instrument for proper collimation. • The ability to electronically collimate a picture after acquisition carries the chance of shedding necessary information. • The ability to electronically collimate an image after acquisition carries the danger of overexposure. • The ability to electronically collimate a picture after acquisition might serve to enhance distinction in the area of interest.
Publication of those circumstances and pictures has been accredited by the institutional evaluate board. In this article we describe the use of electronic collimation as a publish-processing method and illustrate both its usefulness and potential drawbacks. The capacity to publish-course of digital pictures to seemingly optimum pictures has triggered direct suggestions in technical elements to become misplaced.
Loss of this feedback results in a scarcity of optimisation of technical factors, thereby causing unnecessary high ranges of radiation exposure . However, the identical values as in analogue imaging still maintain true . We ought to attempt to maintain the dose low and typically even settle for suboptimal photographs so long as they provide us with the necessary data. This is particularly a topic of concern in paediatric imaging, as youngsters are more weak to the stochastic results of ionising radiation due to a better cell turnover in developing organs and due to their longer life expectancy .
The change from screen-movie radiography to digital imaging has supplied us with many benefits, to which we have rapidly become accustomed. Images are immediately obtainable throughout the whole hospital instantly after acquisition, pictures can be shared amongst hospitals easily, and images may be archived and retrieved without loss of quality. Digital publish-processing methods may suppress artefacts and noise, and serve to increase sharpness and distinction, thereby bettering picture high quality.

Although we don't at present produce honeycomb collimators, we do provide some custom requirements and designs for nuclear purposes for customized analysis projects.
