1. A method of treating varicose veins by application of high intensity focused ultrasound (HIFU), the method comprising the steps of:
identifying a larger segment of a vein which is non-functional, the larger segment of the vein which is non-functional having a plurality of sections including at least one first non-functioning section and at least one second non-functioning section, and identifying the at least one first non-functioning section of the segment of the vein which is to be treated; and
treating the at least one first non-functioning section to be treated by applying high-intensity focused ultrasound (HIFU) emitted from a treatment head to the at least one first non-functioning section without treating the at least one second non-functioning section, of the plurality of sections neighboring the at least one first non-functioning section to be treated, with the high-intensity focused ultrasound (HIFU)
wherein at least one of a number, a length, a location, a characteristic LEED value, a treatment power, and/or a fluence of the first non-functioning section is defined, based on ultrasound imaging data, prior to the step of treating the first non-functioning section
the at least one first non-functioning section to be treated is treated so as to occlude the at least one first non-functioning section.
