Abstract: An intelligent tissue mimicking ultrasonic phantom, which is a temperature-sensitive polymer gel having the following characteristics: acoustic velocity: 1500-1550 m/s; acoustic impedance: (1.50-1.60)×106 Pa·s/m; density: 1.01-1.06 g/cm3; and a denaturation temperature around which there is a reversible phase transformation between the opaque phase and the transparent phase. Said gel can be a polymer of isopropylacrylamide (NIPA). Said ultrasonic phantom has a transparent appearance, and an adjustable thermal denaturation temperature; the thermal denaturation region of the ultrasonic phantom is distinct and has a well-defined boundary; the material of the phantom is stable and deterioration-resistant, and can ensure the consistency of the quality; the phantom is thermal denaturable with the appearance thereof turning white, while the phantom recovers when the heat is removed, such that it can be used repeatedly.

Abstract: An ultrasonic transducer is disclosed, which includes one or a plurality of ultrasonic emitting units. Wavefronts of the ultrasonic waves emitted by the one or the plurality of ultrasonic emitting units are sphere surfaces with uniform radius, and the one or the plurality of ultrasonic emitting units can reflect ultrasound. The one ultrasonic emitting unit is configured to form a spherical resonant cavity, or the plurality of ultrasonic emitting units are configured to form a spherical resonant cavity collectively. An internal cavity of the spherical resonant cavity has a spherical shell shape or a cross-sectional spherical shell shape with a spherical center therein. The ultrasonic waves emitted by the one or the plurality of ultrasonic emitting units are focused on an area in which the spherical center of the spherical resonant cavity is located.
