SYNCHRONISED WITH RESPIRATORY MOVEMENTS ASSESSMENT OF EFFICIENCY OF TREATMENT WITH APPLICATION OF ULTRASOUND CONTRAST SUBSTANCES Russian patent published in 2013 - IPC A61B8/00 G06T7/20 

FIELD: medicine.

SUBSTANCE: invention relates to ultrasound means for diagnostic visualisation. System contains ultrasound probe for obtaining sequence of ultrasound images as perfusion of tissue with contrast substance takes place, multitude of images additionally includes anatomical reference point, showing tissue movement, processor of contrast substance perfusion and image processor, which identifies anatomical reference point and processing images, containing anatomical reference point, separating from processing the images, which do not include it. Method consists in obtaining sequence of ultrasound images of tumour and adjacent to it tissue as perfusion of contrast substance takes place, processing of images to identify tissue movement, with processing of only those images, which have not been subjected to negative impact of tissue movement, in order to determine perfusion parameter, which is a biomarker of treatment efficiency. In the second version of method only synchronised with respiratory movements ultrasound images are selected and normalised parameter of tissue perfusion with contrast substance is separated as related to tumour biomarker.

EFFECT: application of invention makes it possible to increase accuracy in assessment of angiogenesis regression.
