Background: One method for the radiation therapy of rectal cancer is to set patients supine and treat them with volumetric modulated arc therapy (VMAT). The posterior skin dose is of concern due to undesirable bolusing from mounting surfaces the pati...

Background: Interpretation of radiographs is prone to diagnostic errors. Artificial intelligence (AI) has shown promising results in fracture detection, although systematic evaluation of software updates remains limited. This study compares the diagn...

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide. Pulmonary function tests (PFTs) and quantitative indices (QIs) of computed tomography (CT) are typically used to diagnose COPD. The purpose of this work was t...

Breast cancer remains a major global health challenge, with treatment access further constrained during the COVID-19 pandemic, particularly in resource-limited settings. This study evaluates the in vitro effects of hypofractionated versus conventiona...

We compared scatter correction (SC) in single-photon emission computed tomography (SPECT) images using effective scatter source estimation (ESSE) and the triple-energy window (TEW) method. We acquired ^99mTc and ¹²³I images of brain, myocardial, and p...
