Treatment system, method and device.
Background technique
High intensity focused ultrasound (High Intensity Focused Ultrasound, be abbreviated as HIFU) is in recent years
A kind of effective non-invasive therapy technology of the treatment tumour of rise, HIFU utilize the penetrability of ultrasonic wave, focusing, will be high-strength super
Sound focusing makes focus area in the short time to body tumor tissue under the mechanical effect of ultrasound, fuel factor and cavitation effect
Inner focusing very high heat causes protein denaturation downright bad, so that tumour cell is killed, currently with HIFU ablated tumor in clinic
On wide good, malignant tumour applied to the organs such as prostate, uterus, liver, mammary gland.
There are three types of the HIFU types of focusing: single array element self-focusing, sound lens focusing and phased array focus.Phased array is high-intensitive
It focuses ultrasonic (Phased High Intensity Focused Ultrasound, be abbreviated as PHIFU) and utilizes phased array radar battle array
Column principle generates single focus or multifocal sound field pattern, and then form required shape by adjusting the amplitude and phase of each array element
The focal regions of shape, size complete the conformal heating of orientation of target target tissue, realize ultrasonic focusing and scanning in three-dimensional space, from
Under the premise of without Mechanical Moving energy converter, realize that the three-dimensional of ultrasound focus is mobile.List element transducer HIFU relatively and
Acoustic lens energy converter HIFU, PHIFU can be formed different with the more flexible type of focusing according to specific treatment region
Focal intensities and distribution pattern form single focus or multifocal, and beam path control is more flexible, and acoustic beam is avoided to pass through bone etc.
Barrier makes normal tissue from damage, to greatly improve the ablation efficiency of tumour.
