Abstract

Purpose: In this work, we have focused on fabrication and validation of a respiratory belt that produces respiratory signals from the patient’s abdominal and thorax.

Materials and Methods: A load cell transducer was attached to the belt to create an electrical signal from respiratory movement. It converts a force or load into an equivalent electrical signal or digitized load value. The accuracy of the signals from our respiratory control belt was evaluated according to a comparison with the signals from commercial SOMNO medical device.

Results: The pattern of the signals from our respiratory belt is in good agreement (4%/3mm) with the pattern of commercial SOMNO medical device.

Conclusion: The manufactured respiratory control belt can be used during imaging and radiotherapy procedures for breath control in a patient's abdominal and thorax region.
