This study explores the relationship between objective and subjective image quality, using the detectability index ($d^{\\prime}$) as a quantitative performance metric. A 3D-printed anthropomorphic abdominal phantom was used to assess how variations in tube voltage, current, slice thickness, and reconstruction kernel affect image quality. Signal-to-noise ratio, contrast-to-noise ratio, and edge sharpness were evaluated alongside radiologist assessments. A strong correlation between $d^{\\prime}$ and subjective quality confirmed $d^{\\prime}$ as a reliable predictor of visual image perception. Multiple linear regression identified $d^{\\prime}$, object size, and the peak spatial frequency of the noise power spectrum as independent predictors of perceived quality. These results support the integration of $d^{\\prime}$ into routine CT image quality evaluation, helping to align technical image parameters with clinical expectations and improve protocol optimization.<\/jats:p>","DOI":"10.1093\/rpd\/ncaf191","type":"journal-article","created":{"date-parts":[[2025,12,23]],"date-time":"2025-12-23T12:48:59Z","timestamp":1766494139000},"page":"338-345","source":"Crossref","is-referenced-by-count":0,"title":["Evaluating
