Due to the complexity of the HIFU sound field, there has not been a completely ideal method to fully detect the HIFU piezo crystal sound field. The improved radiation balance system and hydrophone have been successfully applied to the measurement of the HIFU field with a sound intensity of 5 kW / cm

The use of HIFU piezo ceramic to treat local tumors, how to enhance the treatment effect and minimize the radiation damage to healthy areas is an important issue. In response to this problem, many researchers have designed and developed some new transducers. Some researchers have proposed to use mul

The current preferred method for curing tumors is still surgical resection. Advances in science and technology have led to the development of open surgery to a smaller trauma. Various interventional is minimally invasive treatment methods, including percutaneous radio frequency ablation and microwav

High intensity focused ultrasound (HIFU) has developed rapidly in recent years and has become a research hotspot in the medical ultrasound engineering field. HIFU surgery is to concentrate the low-intensity ultrasound in vitro into the body through a certain focusing method (acoustic lens, concave s

HIFU piezo for ultrasonc knife has the outstanding advantages of no pain, no surgery, short side effects, short treatment and recovery time, which has become a hot spot in the research of tumor treatment equipment. However, due to its therapeutic effect, it has yet to be extensively clinically teste
