Figure 3 Principles of the high intensity focused ultrasound therapy system.
The FEP-BY Series High Intensity Focused Ultrasound (HIFU) therapy system has the ability to convey HIFU from an external source deep into tissues with a large convergence angle. The focus is oval in shape, with a short axis of approximately 3 mm and a long axis of 10 mm. Transducers have a multi-element array and concave focusing. The angle of convergence is 80°. The size of the focal point is smaller than 3 mm × 3 mm × 10 mm.
