The impact of off‐centered positioning on cone beam CT image quality for image‐guided brain SRS treatment
Quantitative analysis of CBCT image quality in phantoms reveals substantial image degradation with larger FOV and off-centered isocenter positioning. The methods in this study provide insights and a framework for refining scatter correction algorithms to achieve precise scatter adjustments. These developments can be used to enhance CBCT image quality and improve target-alignment-accuracy.
