The probe, under robotic control, then launches focused, high-energy acoustic wave to the tumor to warm and eliminate cancer cells. Depending upon the geometric size and acoustic specifications of the transducers used in a HIFU system, the beam of light dimension of a − 6 dB HIFU system at its focal region is normally 1-- 3 mm in width and about 10 mm in length [9] Nevertheless, a 1 cm cancerous lump is detectable and treatable with HIFU. The standard principles underlying the cells damages from HIFU are tissue coagulative thermal necrosis due to the absorption of ultrasound power during cells transmission (thermal effect) and ultrasound-induced cavitation damages [9] The warm produced by HIFU can result in a fast surge in temperature level in the subjected tissue to more than 60 ° C, which brings about prompt and irreparable cell fatality in many tissues when it lasts longer than 1 s [9] Thermal tissue damages due to heat direct exposure relies virtually linearly on the length of the exposure time and exponentially on the rise in temperature [11]
Sagging skin, specifically around the neck, chin, and jawline, can be considerably improved with HIFU treatment. By targeting the deeper layers of the skin, HIFU gives a more info noticable tightening up effect than numerous surface-level therapies. HIFU functions by targeting deep layers in the skin-- it increases brand-new collagen production and collagen regrowth right at the source. It is occasionally called the 'Lunchtime Facelift' as the therapy is quick, extremely tolerable, and has no downtime.| 欢迎光临 炸弹超人 (http://zhadanchaoren.dhlog.com/) | Powered by Discuz! 7.2 |
