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.
