Systems and Methods for Motion Compensation in Ultrasonic Respiratory Monitoring

摘要

Described herein are exemplary methods, devices, and systems for motion compensation in ultrasonic respiration monitoring. The respiration detection system includes a first probe disposed on an anterior side of the patient's body and a second probe disposed on a dorsal side of the body. The first probe includes an ultrasonic transducer, a first accelerometer unit and a magnetic field sensor unit, and the second probe includes a second accelerometer unit and a magnetic field sensor unit. Due to the patient's breathing, the abdominal region of the body moves, creating measurement errors when the ultrasound beam is directed at an internal structure inside the patient's body (internal tissue region). Correction for such measurement errors uses input data from the first and second accelerometer units and the magnetic field sensor unit.
