Type: article

Abstract: PURPOSE: ), and size-specific dose estimates (SSDEs) from CT images, addressing limitations of conventional console-displayed values that provide only averaged values across scan regions. METHODS: , with Radimetrics software. Agreement was assessed using intraclass correlation coefficients (ICCs) and Bland-Altman analysis. RESULTS: (0.267). For chest/abdomen CT, however, Scanner B showed consistently high agreement, with ICC values ranging from 0.884 to 1.000. CONCLUSION: The developed ImageJ macro provides accurate, transparent, and low-cost open-source solution slice-specific CT dose estimation that correlates well with commercial systems while offering superior spatial resolution. This automated method overcomes the limitations of traditional dose reporting by providing detailed slice-by-slice dose variations, which are often overlooked in average summary values, allowing for more accurate and clinically meaningful dose assessments. CLINICAL SIGNIFICANCE: This tool supports detailed dose evaluation across scan regions, helping optimize protocols and enhance radiation safety. Its slice-specific approach is especially useful in anatomically complex areas and research, offering clinicians more precise dose information to guide patient care.
