Respiratory level tracking with visual biofeedback for consistent breath-hold level with potential application in image-guided interventions
This study aimed to present and evaluate a new respiratory level biofeedback system that helps the patient to have a consistent breath-hold level. The results showed an increased reproducibility of breath-hold expiration level in healthy volunteers, indicating a potential for eliminating targeting errors during lung image-guided procedure.
