Abstract

The invention relates to the technical field of ultrasonic imaging, in particular to a numerical control type low-intensity focused ultrasonic excitation and imaging system. The system comprises a detection probe, wherein the detection probe comprises an imaging transducer, and the detection probe further comprises a spherical-crown-shaped focusing multi-array emitter, the imaging transducer is arranged at the center of the focusing array emitter, and a three-dimensional focus is formed when the focusing array emitter performs focusing in vivo. The numerical control type low-intensity focusedultrasonic excitation and imaging system is based on the digital control technology, and three-dimensional focusing is performed through the spherical-crown-shaped focusing multi-array emitter, so that the focusing range is clearer, and the positioning range and the accuracy of the positioning position are increased during focusing positioning.

Description

Technical field [0001] The present invention relates to the field of ultrasonic imaging, and more particularly to a numerical low intensity focus ultrasonic excitation and imaging system. Background technique [0002] The ultrasonic molecular imaging is to construct the target molecule-specific antibody or ligand to the acoustic contrast agent surface, which actively binds to the target area to perform specific ultrasonic molecular imaging. [0003] At present, the ultrasonic molecular imaging is not only used for diagnosis of disease, but the progress of imaging technology has made the diagnosis and treatment of the disease. Therefore, domestic and foreign scholars are loaded into genes or drugs on the surface or inside of the contrast agent, making ultrasonic contrasts into a safe, convenient non-viral vector, targeted release drugs and genes, thereby achieving the purpose of treating diseases. The size of the ultrasonic microvescoal film is comparable to the red blood cells, w...
