Abstract
The method of characterizing an ultrasound lesion (T) in organic tissues, the lesion being made by applying high intensity focused ultrasound delivered by a probe having its emission surface presenting a shape that is toroidal, consists in: after a period of at least two days from the end of ultrasound application, acquiring at least one characterization image (Ic) of the organic tissues; detecting the presence of a contrast border (16) in the characterization image (Ic); and from the contrast border (16), determining the extent of the ultrasound lesion.
Claims22
A method of determining an extent of an ultrasound-generated lesion in an organic tissue, the ultrasound generated lesion being made by applying high intensity focused ultrasound delivered by a probe comprising an emission surface having a shape that is toroidal or pseudo-cylindrical, the method comprising:
- acquiring a reference image of the organic tissue prior to applying the high intensity focused ultrasound;
- applying the high intensity focused ultrasound delivered by the probe;
- after a period of at least two days, but less than thirty days, from the end of the high intensity focused ultrasound application, acquiring at least one characterization image of the organic tissue;
- detecting a presence of a contrast border in the characterization image using digital image processing;
- wherein the contrast border is in a form of a line having a light intensity that is greater than a light intensity of surrounding tissue;
- wherein the contrast border corresponds to precipitated calcium;
- and
- determining the extent of the ultrasound-generated lesion from the contrast border after processing the reference and characterization images using digital image processing.
A method of treating and characterizing a biological tissue in a mammal, the method comprising:
- acquiring a reference image of the biological tissue prior to applying high intensity focused ultrasound to the biological tissue;
- applying high intensity focused ultrasound to the biological tissue using a probe comprising an emission surface having a shape that is toroidal or pseudo-cylindrical;
- after a period of at least two days, but less than thirty days, from the end of the high intensity focused ultrasound application, acquiring at least one characterization image of the biological tissue;
- detecting a presence of a contrast border in the characterization image using digital image processing;
- wherein the contrast border is in a form of a line having a light intensity that is greater than a light intensity of surrounding tissue;
- wherein the contrast border corresponds to precipitated calcium;
- and
- determining, from the contrast border, an extent of a lesion in the biological tissue made by applying the high intensity focused ultrasound, after processing the reference and characterization images using digital image processing.
