Focused ultrasound treatment system based on ultrasound imaging

A focused ultrasound treatment system based on ultrasound imaging, comprising:

• a focused ultrasound unit, configured to emit focused ultrasound waves to a lesion region for treatment;
• an ultrasound imaging unit, configured to, after the treatment, emit imaging ultrasound waves to an imaging region and receive corresponding echoes, and based on the echoes, form a corresponding vascular blood flow image;
• and
• a region planning and parameter adjustment unit, configured to, based on the vascular blood flow image;
• determine a vascular blood flow network contour of the lesion region;
• determine a vascular density index, a blood flow velocity index, and a blood flow volume index of the lesion region based on the vascular blood flow image, and re-delineate the lesion region according to the vascular blood flow network contour;
• score a lesion state of the re-delineated lesion region according to one or more of the vascular density index, blood flow velocity index, and blood flow volume index to obtain a scoring result, compare the scoring result with an expected result, and
• re-adjust the treatment parameters of the focused ultrasound unit based on a result of the comparison for the next treatment of the re-delineated lesion region,
• wherein the imaging region comprises the lesion region;
• and
• the vascular blood flow image is a microvascular blood flow image, wherein a spatial resolution of the microvascular blood flow image is less than or equal to a wavelength of the imaging ultrasound waves emitted by the ultrasound imaging unit, the spatial resolution and the wavelength each being measured in units of length.
