Occurrence of cr artifacts and remedial measures taken in a tertiary hospital

Background: Computed radiography which can capture a latent analog images, which is been then digitized in the Reader. During the translation process there is a chances were artifacts can be produced in the image which can result in non-clinically acceptable for diagnosis. Aim: The aim of this study is to evaluate the CR artifacts, with frequency of occurrence and the types of artifacts occurring with remedial measures. Materials and Methods: Sampling was done by convenience sampling method considering inclusion and exclusion criteria and a sample of 550 was taken frequency of images with artefact and without artefact was calculated Further the artefacts were categorised in two groups as Image processing artefacts and Image Acquisition artefacts and their frequency of occurrence was calculated and statically analyzed. Result: Out of 550 images with artefact were 184 (33%) and without artefact was 366 (67%). Among 184 images with artefacts, 102 images were with image acquisition artefacts which form 55.4% and 82 images were with image processing artefacts which form 44.5% of total images with artefacts. Conclusion: Appropriate periodical maintenance and QA may be helpful to produce optimum quality image and quality patient care, decreasing CR artefacts and avoiding repeat radiographs thus optimizes the radiation exposure to patient and radiographer.
