Assessing Radiographic Technologist Precision and its Influence on Patient Exposure Index: Analytical Retrospective Study in a Small Palestinian Government Hospital

This observational retrospective study conducted at Hussein Governmental Hospital in Bethlehem, Palestine, aimed to compare internationally recommended exposure levels with the actual exposure settings employed by radiation technologists. Inclusive of both genders and diverse age groups, the study utilized Toshiba flat panel detectors and closely observed exposures across various radiographic image types. Data analysis, performed using SPSS, included a one-sample t-test, ANOVA, and Pearson correlation. The results revealed that, on average, the current Exposure Index (EXI) did not significantly differ from the recommended standards, indicating the proficiency of technologists. However, deviations were observed in Kilovoltage Peak (kVp) settings, emphasizing the need for technologists to interpret automatic exposure controls accurately. The study found no significant differences in EXI related to image type, gender, or age, affirming the logical correlation between parameters and distinct exposure indices. Notably, a significant relationship was observed between acceptance by technologists and the Deviation Index, suggesting challenges in visually distinguishing accepted and rejected images. This study assesses radiation technologists' adherence to international exposure standards using Toshiba detectors. While overall compliance is observed, deviations in Kilovoltage Peak settings indicate a need for improved control interpretation. The findings contribute to optimizing radiation exposure and image quality in clinical radiography, particularly in resource-constrained settings.
