Accelerometer-Based Method for Extracting Respiratory and Cardiac Gating Information for Dual Gating during Nuclear Medicine Imaging

Figure 8

Assessment of correlation between the ADR and reference respiration signal shows a high correlation in regard to respiration cycle duration across normal breathing (a), slow-paced breathing (b), and fast-paced breathing (c).

(a) Correlation of the respiratory cycle duration (normal breathing)

(b) Correlation of the respiratory cycle duration (slow-paced breathing)

(c) Correlation of the respiratory cycle duration (fast-paced breathing)
