Respiration Detection

Abstract

An apparatus for detecting respiration including: a signal acquisition unit configured to continuously acquire RGB signals of a subject; and a signal processing unit configured to receive the RGB signals, and determine a respiration phase, amplitude, and frequency of the subject. The apparatus automatically captures respiration signals of the subject and sends them synchronously to a physician in a control room for various types of CT scan without the need to introduce invasive or contact-type equipment. Many scanning protocols involve regions of the body that are affected by respiratory motion, so ensuring that the patient holds his breath in the exposure stage is crucial for image quality. Advanced applications may be provided according to the respiration signals acquired; apart from visualized respiration signals, warnings may be issued to the physician when the patient is unable to hold his breath.
