Monitoring of patients using radiodiagnostic dosage EI (Exposure Index) on CR (Computed Radiography)
Keywords:CR, dose monitoring, EI, modality, radiographer
Most of the current radiographic examinations have used digital technology, one of which is for image readers and image processing using the CR (Computed Radiography) modality. The use of CR is more advantageous than film-screen systems because it has faster image acquisition and processing, a wide dynamic range, easy contrast adjustment, brightness, and electronic cropping. Unfortunately, the amount of exposure radiation is difficult to assess when using digital imaging compared to screen-film systems. Based on field observations, a radiographer tends to ignore the EI (Exposure Index) value in the application of the CR modality. The success of the radiographer in the radiography process is limited to the image that is not repeated. Even though the image quality factor is not merely a matter of repeated images or not, but also those who have the breadth of information and also must maintain protection principles for patients, in this case, is the acceptance of the dose due to radiography. So it is necessary to monitor the patient's dose using the EI value.
