An assembly of electrically-powered devices designed to treat solid tumours of hard (bone) and/or soft tissue [e.g., liver, kidney, breast, prostate] and/or gynaecological disorders (e.g., uterine fibroid, adenomyosis) through noninvasive or non-surgically invasive localized application of high intensity focused ultrasound (HIFU) or high intensity therapeutic ultrasound (HITU) intended to gradually denature/ablate tissue lesions. It typically consists of a piezoelectric transducer (probe), a water supply/power control unit, operator console and monitoring systems, software, and sometimes a patient table. Optimal patient positioning is achieved using an ultrasound scanner or MRI system.
