Description
Technical Field
The utility model relates to a medical ultrasonic testing technology field specifically is a calibrating device of supersound appearance.
background
in high intensity focused ultrasound treatment, temperatures at the focal site can reach 60 ℃ to 90 ℃, while normal tissue is generally not more than 45 ℃ and up to 46 ℃ resistant to heat, which requires precise control of the shape and location of the focal zone. The key link of the HIFU technology is to precisely control the phase of the ultrasonic beam emitted by each array element, namely, the focus tissue in the human body can be precisely positioned on the premise of considering the nonuniformity of the human body structure. The clinical findings show that due to the non-uniformity of human tissues, when a focal point is deep, the focusing effect of the ultrasonic beam is not very accurate, and the propagation direction of the ultrasonic beam around the focal target area changes nonlinearly, which results in the change of the temperature field distribution around the focal target area, that is, the ultrasonic beam is not focused on the focal target area, and the actual focal point shifts or defocuses (a large focusing region is formed instead of forming a focal point), that is, the focal region is not at the focal point, or the volume of the focal region is large. Such a result often results in the inability to completely eliminate the tumor and the potential for unnecessary damage to normal body tissue surrounding the target area, and thus the particular size of the focal zone in which the ultrasound is focused is important.
