23 Jul Harmless temperature measurement device based on B-ultrasound focused in ultrasound field
Abstract
The invention relates to a nondestructive temperature measuring device based on type-B ultrasound in a focused ultrasound sound field, which belongs to the technical field of biomedical engineering. The nondestructive temperature measuring device comprises a combined probe consisting of an HIFU transducer probe and a type-B ultrasonic probe, a thermocouple thermoprobe, a positioning board for the thermocouple thermoprobe, and a water tank. The thermocouple thermoprobe is positioned on a focal region part of a heating organism through the positioning board for the thermocouple thermoprobe; the positioning board for the thermocouple thermoprobe is fixed at one end of an upper cover of the water tank; an opening of the water tank is opened upward, the lower part of the water tank is provided with a round opening, and the water tank is fixed with the HIFU transducer probe; and the binding site of the water tank and the HIFU transducer probe is provided with a waterproof rubber ring. The combined probe allows a type-B ultrasonic image to better reflect the focal region changes; the positioning board for the thermocouple thermoprobe can help to accurately position the focal region on an organism tissue to be heated; and the nondestructive temperature measuring device has the function of detecting a true temperature field in an organism in real time accurately. The nondestructive temperature measuring device has the advantages of small volume, simple implementation, and convenient operation.
