A simple device for breath-level monitoring during CT.
Computed tomography (CT) of the chest and abdomen requires well-defined and reproducible breath-holdings. For this purpose, a simple respiration-control device has been developed that enables the patient to monitor breath-holding during successive scans. The patient holds his/her breath at a preselected level using feedback monitoring. The device is easy to handle and suitable for all commercial CT systems.
