Phased arrays are widely configured in high-intensity focused ultrasound (HIFU) platform due to the ability of fast switching focal spot (FS). Nonetheless they cannot yet be used in most of ultrasonography-guided HIFU (USgHIFU) systems because of difficulties in monitoring. To overcome these obstacles, the prototype of a 112-channel phased-array USgHIFU system was designed. The most unique feature...
The appearance of hyperecho is clinically considered as an indicator of tissue necrosis for ultrasonography-guided high-intensity focused ultrasound (USgHIFU). Nevertheless, there is unobservable hyperechoic change in the absence of cavitation or boiling during sonication. A quantitative analysis that could identify post-sonication change in the ultrasound image is proposed for the detection of HIFU-induced...
