The advantages of mobile or portable CXR in Covid-19 patients are minimal radiation received compared to CT SCAN, as well as monitoring or evaluating patient diagnoses in the Intensive Care Unit (ICU). CXR in the Anterior Posterior (AP) projection with Covid-19 patients lying supine or sitting in the ICU are usually uncooperative in adjusting the patient's position, resulting in low image quality, thus requiring Digital Imaging (DIP) in an effort to improve image quality. This study used DIP Contrast Limited Adaptive Histogram Equalization (CLAHE) on images of Covid-19 patients in the ICU, and compared pre and post CLAHE on quality and pathological information
