ABSTRACT
Respiration-induced displacements of organs greatly affect the safety and efficiency of high intensity focused ultrasound (HIFU) tumor therapy system. The key to solve this problem is accurate, real-time detection of respiratory signals. The present study gives a new design of an interface compatible non-contacting respiratory signal detection system using the method of irradiating the laser beam onto certain region of the surface of human body that is intensely influenced by the breathing movements (mostly the breast or the dorsum) at a certain angle, and meanwhile using a camera to acquire information from the location of the laser projection. Then we can draw a curve of the location of laser projection versus time base, that is the respiration curve. This respiratory signal detection method is non-contacting, interface compatible and easy to be integrated into the treatment system.
