Abstract

The invention relates to a focused ultrosound therapy combined array element phased array and multifocal shear wave imaging system for focused ultrosound non-invasive surgical therapy, belonging to the technical field of biomedical instrument, in particular to a combined array element phased array transducer used for multifocal focused ultrosound therapy and radial force excitation imaging and also relates to a multifocal plane shear wave imaging system by using the combined array element phased array transducer. In the transducer, the combined array element is formed by compactly placing 2*2 or 3*3 basic matrix array elements in rows according to spherical rectangle mode, all basic matrix array elements in each combined array element are in parallel electrically and share one power driven channel; a basic matrix array element distance is left between the centers of two adjacent combined array elements along at least one direction, and each combined array element is matched with the phase and amplitude of one power driven channel so as to significantly expand the focal scanning area.

Description

technical field

[0001] The invention belongs to the technical field of biomedical instruments, and relates to equipment for focused ultrasound non-invasive surgical treatment, in particular to a combined array element phased array transducer, which is applied to multi-focus focused ultrasound treatment and radiation force imaging excitation; And a multi-focus planar shear wave imaging system using the combined array element phased array transducer. Background technique

[0002] Focused ultrasound surgery (FUS) is a treatment method that focuses ultrasonic energy on deep target tissues in the human body to precisely select thermally damaged target tissues without harming adjacent normal tissues. It is currently mainly used in the non-invasive treatment of tumors treat. Focused ultrasound surgery belongs to the high-energy treatment of therapeutic ultrasound (Therapeutic ultrasound), and the treatment of lower energy in therapeutic ultrasound, such as focusing on bone repair,...
