摘要：
PURPOSE: A method and apparatus for forming multiple focal points with an ultrasound transducer array are provided to remove grating lobes with forming the focal points when operating a high intensity focused ultrasound (HIFU) apparatus, thereby shortening the treatment time of the HIFU apparatus.CONSTITUTION: A method for forming focal points for ultrasound treatment includes: a step of selecting at least one candidate focal position among the focal positions of a region in which ultrasound for the treatment is irradiated a step of determining whether or not negative pressure is generated in the focal position excluding the selected candidate focal position in which the focal point of the ultrasound is formed and a step of determining the candidate focal position, in which the negative pressure is not generated, into a group of the focal position to which the ultrasound is irradiated. An apparatus forming focal points for the ultrasound treatment includes a candidate focal point determining part (102), a focal point formation determining part (103), and an optimal focal point determining part (104).COPYRIGHT KIPO 2013[Reference numerals] (101) Object point determining part (102) Candidate focal point determining part (103) Focal point formation determining part (104) Optimal focal point determining part (106) Memory (107) Interface (108) Irradiating determining part (109) Optimal focal point storing part초음파 트랜스듀서 어레이의 다중 초점 형성 방법 및 장치가 개시된다. 이와 같이 개시된 방법 내지 장치에 따르면, HIFU장치의 동작 시 그레이팅 로브(Grating lobes) 현상을 없애면서 여러 개수의 초점을 동시에 형성하여 HIFU장치를 이용하여 치료시 병변의 주변에 장기의 손상을 방지할 수 있다.
