1/3/2024 0 Comments Radiation exposure x ray![]() In digital imaging, a lack of collimation or discarding apparently non-useful images can lead to a need for repeat imaging and increased patient exposure. For instance, studies have shown that the use of automatic exposure control (AEC) can significantly reduce patient dose. A high benefit/risk ratio for radiological procedures is to a large extent dependent on correct procedure selection, proper technique, and quality control. There are several ways of reducing radiation exposure of patients and minimizing risk without compromising the health benefits of a radiological procedure. Techniques such as virtual collimation and pulsed fluoroscopy decrease patient dose with either no effect or only a slight degradation in image quality. What are some of the methods of reducing radiation exposure? What can X-ray techs do to follow the ALARA principle and ensure the safety of their patients? High-dose mode is associated with an improvement in image quality but is associated with a high radiation dose to the patient. Similarly, magnification improves spatial resolution and image quality but may lead to an increase in skin dose. In digital fluoroscopy, an increase in the number of images per exam reveals greater diagnostic information but is associated with an increased dose. ![]() But, exposure to ionizing radiation can be harmful to patients. ![]() A fluoroscope with an overcouch configurationÄigital imaging techniques provide important information to healthcare professionals.
