X-ray machines are equipped with collimators that permit adjustment of the size of the beam to fit the dimensions of the world being radiographed. Radiographic examinations have to be carried out with correct respect for radiation safety procedures. In addition, proper collimation is required for digital reconstruction algorithms to work correctly. Scatter radiation can also be the major supply of radiation exposure to operators, so proper collimation is essential to decrease this threat. Veterinarians most incessantly use nuclear drugs imaging to investigate the lungs, kidneys, liver, thyroid, and heart, although different portions of a pet’s body may be studied with this method. This decreases the quantity of scatter radiation generated, improving picture distinction and element. The exposure elements used in modern x-ray methods are considerably decrease than those used up to now however can still lead to injury. As digital imaging technologies become more prevalent, it’s essential for veterinary practices to adhere to regulatory tips and implement best practices.

In many display systems, the algorithm could be altered to provide enhancement of varied options of the image. In both techniques, the data produced are processed by a computer, which generates the picture on a monitor based on a beforehand determined processing algorithm that is specific to the region being radiographed.
