confirmed reference values of tissue-equivalent materials within a root mean square error of 1%. The AI-supported extended field-of-view reconstruction showed better agreement with ground-truth than the conventional algorithm, even if large phantom parts were located outside the scan field-of-view (Figure 2). Multi-phase respiratory 4D reconstructions showed displacement errors below 1mm for a sphere moving in scan direction.
