Optimal Frame Summation for Motion Correction in Sinusoidal Periodic Motion:

Key Points

• This study aims to identify optimal frame summation conditions for correcting body movement during sinusoidal motion in pediatric nuclear medicine.
• Examined motion correction based on inter-frame alignment under sinusoidal periodic movement.
• Assessed the influence of ellipse ratio and centroid stability on image quality.
• Optimal frame summation significantly reduced image distortion compared to standard methods.
• Enhancements in centroid stability improved image quality metrics by 30% (p<0.05).
